4. Welding Feature Safety

1. Eye and Ultraviolet Radiation Hazards

Welding generates visible and invisible radiation, which can pose risks to welders. The high-power laser beam’s interaction with the material being welded can create plasma, emitting ultraviolet radiation and “blue light.” These emissions can lead to conjunctivitis, photochemical damage to the retina, and skin reactions similar to sunburn. Welders exposed to UV light without adequate protection may experience permanent eye damage.

2. Skin Hazards

Welders are at risk of skin damage from infrared and ultraviolet radiation during welding. These types of radiation can cause skin burns, increase the likelihood of skin cancer, and promote premature skin aging. Welding sparks can also lead to burns. Laser material processing can cause parts to become extremely hot even after the cutting process has ended. It is essential to use appropriate personal protective equipment to avoid potential burns. To prevent skin damage, wear protective clothing such as heat-resistant gloves, hats, leather aprons, and other flame-resistant garments. Button up sleeves and collars.

3. Fire Hazards

The heat and sparks generated during welding can ignite or explode flammable materials near the welding area. Only perform laser welding in areas clear of combustible materials. Never weld containers that contain, or are assumed to contain, flammable or combustible materials. Ensure fire extinguishers are easily accessible and nearby, and have personnel trained to use them.

4. Smoke and Fume Hazards

Welding “fumes” can consist of fine particles and gases produced by the combination of welding materials, filler materials, shielding gases, paint, coatings, chemical reactions, and air pollutants. Welding fumes can negatively impact the lungs, heart, kidneys, and central nervous system. To mitigate these risks:

  • Keep the head away from the smoke while welding. Always work in a well- ventilated area to ensure safe breathing conditions.
  • Implement a fume extraction system to remove vapors, particulates, and hazardous debris from the welding process area.
  • Use a respirator in confined spaces or other situations where it may be required.
  • Conduct regular air monitoring to determine the level of noxious fumes in the welding area.

5. Cylinder Safety Measures

A gas cylinder poses a risk of explosion if it is damaged or situated close to the welding zone. To ensure safety, place shielding gas cylinders in a secure location where they are not susceptible to impact or damage, and maintain distance from sources of heat, sparks, or flames. It is essential to store the cylinders in an upright position and fasten them securely to a stationary stand. Utilize a functioning regulator specifically designed for the intended gas and pressure. Additionally, verify that all hoses and fittings are appropriate for their intended application and are in optimal working condition.

6. Important Safety Notice for Outbound Security Indicators:


It is crucial to be aware that when the power  supply (PS)  is activated,  the laser is in a hazardous state. Every necessary precaution must be taken to prevent accidental exposure to direct and reflected beams. Both diffuse and specular reflections can lead to severe retinal or corneal damage, potentially causing permanent eye damage. Class 4 laser beams may also pose fire and skin damage risks when handling equipment or being in its vicinity. Ensure that all personnel wear appropriate personal protective equipment (PPE), including safety gogglesand helmets with face shields.

1. Secondary radiation hazard

During the welding process, both visible and invisible light radiation are generated. The interaction between the high-power laser beam and the target material being welded can result in the production of ultraviolet (UV) light and plasmas that emit “blue light.” These radiations can lead to various health issues, such as conjunctivitis, photochemical damage to the retina, and sunburn-like reactions on the skin.

Welders who are exposed to these invisible UV rays without appropriate safety measures are at risk of incurring permanent  eye damage. Even a short exposure   to the UV rays during welding can lead to symptoms like blurred vision, burning, tearing, eye pain, and irritation — often described as a sensation similar to having sand in the eye.

2. Precautionary Measures for Welding Protection and Minimizing Risks in Welding Processes


◎ To safeguard your eyes from harmful conditions during welding, it is crucial to wear appropriate personal protective equipment! Employing a combination of a mask, gloves, welding helmet, and laser safety glasses can effectively mitigate the effects of wind speed and equipment noise. During welding operations, ensure that you are wearing anti-noise earplugs to achieve optimal protection throughout the laser welding process. Welding helmets also shield welders from risks such as heat splatter, metal fragments, and sparks. All individuals in the vicinity of laser welding activities must also be equipped with proper personal protective gear.

◎ Hazards during welding —– Wear personal protective items!


◎During welding processes, be mindful of potential hazards and take necessary precautions. Ensure that all combustible and flammable materials are kept at  a  safe distance from the welding area, as heat and sparks produced during welding may result in fires or explosions. Limit laser welding  operations  to  designated areas free of combustible materials.

Avoid performing welding tasks on containers holding flammable or combustible substances. When the contents of containers are uncertain, treat them as  potentially dangerous. Additionally, always keep a fire extinguisher nearby, and ensure that all welding personnel have undergone comprehensive training in fire extinguisher usage.

3. Dangers of Reflected Beam in Welding Process


◎Beware that during the welding process, numerous secondary laser beams, known as “specular reflections,” can be generated at various angles  near  the laser’s output aperture. Specular reflections occur when the main laser beam reflects off the surface it is directed at, and can be produced due to the interaction between the laser beam and the treated part.  Although  these secondary  beams are not as powerful as the laser’s total emitted energy, they are potent enough to cause harm to the eyes, skin, and surrounding materials.

Take extra precautions when working with highly reflective metals, such as aluminum and copper, as they may  cause some of  the beam energy to reflect  away from the target weld site. Moreover, specular reflection can pose a threat to the operator if any part of the beam is reflected from more than  one  surface. Ensure that you are aware of the anticipated specular cone  for each machined  part, and avoid looking at or placing any part of your body within the expected specular cone.


◎Operators and observers must always remain vigilant about potential reflections. If the laser settings are not configured correctly to ensure the target portion melts, increased reflection may result.

To ensure safe operating conditions, follow these steps:

  1. Choose the suitable mode based on the material and thickness;
  2. Select the right nozzle according to the joint geometry.


  • To ensure safety, equipment operators are advised to use only the jet nozzle tip. For the part number of Maxphotonics nozzle tip kit, refer to the table in Figure 6-1. Replacement nozzle tips can be purchased as needed.
  • For the proper angle and position of the welding gun, consult Figure 6-1.

4. Hazard of Welding Smoke


◎ Beware of the dangers of inhaling welding smoke!

Welding “smoke” encompasses a mixture of fine particles and gases that are created during the welding process. This smoke originates from the materials being welded, filler materials, shielding gases, coatings, paints, chemical reactions, and air pollutants. Exposure to welding fumes can negatively impact the lungs, heart, kidneys, and central nervous system. The laser interaction with target materials like plastics, metals, and composites may cause them to evaporate, producing toxic and hazardous smoke and fog which are often invisible but pose serious health risks. Performing welding tasks in enclosed spaces with poor ventilation is extremely dangerous, as toxic smoke and gas concentrations can quickly build up, leading to coma or asphyxiation. The ultraviolet light emitted during welding reacts with oxygen and nitrogen in the air, producing ozone and nitrogen oxides, which can be lethal at high concentrations. Shielding gases used in welding can displace air and cause harm or even death.

  • To prevent exposure to hazardous fumes during welding, keep your head away from the fume source and always work in a well-ventilated area.
  • Implement smoke extraction systems to capture and remove dangerous fumes, vapors, particles, and debris from the welding workspace.
  • Review and adhere to the safety data sheets and warning labels for all welding materials being used.
    • In confined spaces and other high-risk situations, the use of respiratory  protection may be necessary.
    • Regular air monitoring should be conducted to ensure that hazardous smoke levels are kept in check within the welding environment.

5. Cylinder safety


◎Be cautious that gas cylinders may explode if damaged or located close to the welding zone. It is crucial to protect and position them in a secure area, away from potential hazards such as impact damages, heat, sparks, or flames. Ensure that cylinders are stored in an upright position and securely fastened to a fixed bracket. Utilize a compatible regulator designed for the necessary gas and pressure requirements. Additionally, confirm that all hoses and fittings are appropriate for the intended purpose and maintained in good working condition.

Chapter 6 – Operation Guide

1 – Notice

◎ Please refer to Chapter 4 “Detailed Specifications” to select a suitable power supply. To select an appropriate power supply, kindly refer to Chapter 4 “Detailed Specifications.

◎ To ensure the peripheral working environment of the laser meets safety

requirements, consult Chapter 2 “Safety Information.

◎ Prior to laser welding, please wear the provided soundproof earplugs for your protection.

2 – Electrical Power Connection Guidelines

  1. The laser’s power input line must be connected to a single-phase alternating current (220VAC) using a 25A industrial power source.
  • It is strictly prohibited to connect the power cord directly to a household electrical outlet.
  • Ensure that the power cord is connected to the  appropriate  voltage  and phase: L=220VAC, N=0VAC, and PE=ground. Verify that the wiring is correct before operating the machine, and never neglect the PE connection.

For enhanced safety, Maxphotonics strongly recommends connecting a 32A circuit breaker (air switch) in series between the power supply and the laser. Ideally, position the power supply near the device’s power supply unit for easy disconnection.

If you have further questions about the power connection, kindly consult Chapter 4, “Detailed Specifications,” to ascertain the product’s electrical specifications. To ensure safety, only qualified personnel familiar with electrical safety and wire connections should carry out electrical connections. Additionally, wiring must  adhere to all national and local regulations

3 – Electrostatic Grounding Process

It is essential to ensure a secure and reliable connection between the laser housing’s grounding nut and the ground using a grounding wire, in order to prevent any potential damage to the laser due to static electricity.

As illustrated in the wiring diagram:

Attach one end of the grounding wire to the ground stud:

Connect the other end of the grounding wire securely to the outdoor grounding pole.

4 – Securely Lock the Connection

Ensure a Secure Connection Before Activating the Laser

Prior to switching on the laser, it is crucial to attach the safety lock to the loop interface of the laser device. During laser preparation, fasten the other end of the safety lock (alligator clip) onto the workpiece. This ensures that the alligator clip and the welding head form a complete loop, allowing the laser to function properly and output laser energy safely.

5 – Safely Secure the Gas Connection

The welding head is cooled by inert gas, which requires maintaining optimum gas purity and air pressure. Typically, nitrogen and argon serve as shielding gases. The shielding gas purity must be 99.99%, and the input gas pressure should range from 80Kpa to 500Kpa. For an effective welding process, it’s essential to use a pressure- reducing valve with a flowmeter (nominal flow rate of 25L/min) to accurately control the airflow.

Connect the 6mm outer diameter gas pipe to the Gasin port, and adjust the gas flow rate to 15-20L/min. Choose the normally open gas valve mode (found in the advanced settings interface) to regulate the gas flow.

6. Due to the different equipment configuration (wire feeding machine differences) and welding methods (wire feeding speed, air  pressure, degree  of  deflection, welding  Angle) adopted  by different  customers,  this  data is  for reference only.


Please refer to the above process parameters for stack welding, fillet welding, lap welding, etc.

14. How To Use The Fish Scale Function

Method 1: Enable the fish scale pattern on the home page

The fish scale pattern has built-in default parameters, so you don’t need to set them. Simply turn on the switch:

  1. Firing time: 150ms
  2. Interval: 40ms

For optimal fish scale effects, use the wire feeding machine parameters and set the wire feeding speed according to 7-10.

Method 2: Access the Professional mode.

In the Settings, set reasonable firing duration and interval times:

  1. 1.Ignition duration: 150ms (this parameter affects the size of the welding striatum)
  2. 2.Interval time: 40ms (this parameter affects the interval between two striatum) Fish scale pattern welding (In this mode, only the laser is turned off during the interval, and other settings such as on/off time do not affect or take effect) Simply set the spot welding duration and interval to produce the fish-scale welding effect. Note: It is recommended to use fish- scale pattern welding at 50% power. If it is necessary to use fish-scale pattern under high power, do not use a large welding angle and use appropriate positive defocus (gun barrel scale: +2 to +4 range) to increase gas flow and reduce welding splash. This can prolong the service life of the protective lenses.

In the wire feeder parameters, select “pulse”:

  1. Pulse period: 140ms
  2. Pulse wire feed speed: 10mm/s
  3. Pulse smoothness: 20%

Note: When using the pulse mode for the wire feeder, set the laser light output to continuous mode.

15. Product Accessory Inspection and Cleaning Guide

1. Inspecting Product Accessories:

To clean the tip protection mirror window, gather the following equipment:

  • Powder-free rubber gloves or finger cots
    • Lint-free fiber cleaning cloth and cotton swab
    • Optical grade alcohol (purity >99.5%)
    • Light source (flashlight or mobile phone indicator)
    • Masking tape
    • Microscope


◎ Before using this product, please check the cleanliness and integrity of the protective lens. Operating with a dusty or damaged protective lens may cause damage to the welding torch head (focusing lens, extension tube, etc.) and affect welding quality.

◎Unauthorized disassembly of the gun head and laser products will void the Maxphotonics warranty.

◎ Please wear powder-free gloves or finger cots when cleaning the product in a dust- free environment. Maxphotonics is not responsible for tip damage due to improper operation or incorrect cleaning procedures.

◎ When cleaning, the concentration of alcohol should be greater than 99.5%.

2. Cleaning Steps Follow these procedures to clean and maintain the laser welding machine:

  • Turn off the laser switch and disconnect the power supply;
  • Rotate the locking screw on the protective mirror housing from the gun head  and pull out the mirror holder (sealed with clean masking tape to prevent dust from entering). Use an optical cleaning cloth dipped in alcohol to wipe the entire protective mirror window surface;
  • Hold the window in the left hand and place it under the microscope (20x magnification);
  • With the right hand, adjust the focal length of the microscope so that the protective lens surface is clearly visible;
  • Carefully examine the protective lens surface. If dust or tiny particles are present, use a cotton swab to clean them:

① Dampen a cotton swab with alcohol, shaking off any excess;

② Position the cotton swab on the dust location on the lens under the microscope;

③ Gently wipe the dust with the swab, moving it towards the edge of the lens, and replace the swab after use;

④ After cleaning all debris, verify cleanliness under the microscope.

  • Insert the cleaned protective lens into the lens holder;
  • Place the protective lens holder into the gun head’s lens cavity seat and fasten the locking screw on the lens holder shell to secure the lens holder in place..


◎ Do not reuse lint-free cotton cloth or cotton swabs..

◎ Do not touch the welding torch head’s protective lens with your fingers.

◎ Do not blow directly on the lens surface with your mouth as this may introduce new debris.

◎ Do not touch the cleaning swab’s tip with your fingers..

◎ Remember to clean the protective cover and sleeve when replacing them.

◎ When using compressed air, avoid blowing debris directly at the surface, and

instead use a side-blowing technique.

◎ If the protective lens holder cannot be immediately reinstalled, seal the lens cavity shell with textured paper
