As a high-precision, high-efficiency processing tool, the stable operation of a laser welding machine directly impacts product quality and production efficiency. While equipment longevity
depends in part on manufacturing quality, it is equally influenced by daily operating habits and maintenance practices.
Drawing on years of industry experience, Foster Laser has developed a practical maintenance guide to help users improve equipment stability and significantly extend service life.
First Standardized Operation and Proper Storage to Prevent Hidden Hazards
Hang the Welding Torch Vertically to Avoid Lens Damage
After each use, the portable laser welding machine handheld torch should be hung vertically rather than laid flat on surfaces. Horizontal placement may allow dust to settle on the
focusing lens, increasing the risk of “burned lens” due to laser energy concentration. It is recommended to use lint-free wipes with anhydrous ethanol to clean the inner wall of the scale tube in
a single direction, removing welding spatter and debris to avoid carbonization during the next operation.
Coil the Armored Cable Neatly to Prevent Damage
During and after operation, avoid pulling or dragging the armored cable or machine. Instead, coil cables neatly to prevent crushing, excessive bending, or physical stress that could damage fiber
optic lines or power cables, affecting laser transmission and system stability.
Second Routine Cleaning and Scheduled Maintenance to Ensure Stable Performance
Scale Tube Cleaning
Wipe the scale tube every two days to remove welding residue. Regular cleaning prevents carbon buildup, maintains beam path integrity, and supports efficient heat dissipation.
Air Filter Maintenance
Air cooling systems and air inlet filters should be cleaned weekly (or based on usage frequency). Blocked filters can lead to poor heat dissipation, risking premature failure of internal
components.
Third Proper Electrical Connection to Ensure System Safety
Separate Grounding for Laser and TIG Welders
Automatic laser welding machine and TIG welder must not share the same grounding system. High-frequency interference from TIG welders can be transmitted through shared ground lines,
potentially disrupting laser control signals and accelerating wear of electronic components.
Correct Equipment Handling
Never move the machine by pulling cables or armored conduits. Use the base structure or dedicated transport handles to prevent internal cable loosening or breakage.
Fourth Environmental Considerations to Optimize Operational Stability
In dusty or high-humidity environments, use protective enclosures or dust covers to shield the equipment.
If the machine will be idle for an extended period, shut off power, store it in a well-ventilated, dry space, and run periodic self-checks.
Maintain a stable power supply to prevent voltage fluctuations that could impact the laser power supply or trigger system faults.
Handheld mini metal optical laser welding machines are high-value, precision tools, and every detail of their maintenance contributes to extending their lifespan. Foster Laser is
committed not only to delivering high-performance equipment but also to providing comprehensive maintenance advice and technical support.
