As a high-precision, high-efficiency industrial processing tool, the performance and lifespan of a laser welding machine portable directly affect production efficiency and welding quality. The stability and durability of such equipment depend largely on standardized daily operation and routine maintenance. Based on years of industry experience, Foster Laser, a professional laser equipment manufacturer, has compiled a set of practical and professional maintenance recommendations to help customers prolong the service life of their equipment while ensuring welding quality and operational safety.

First Proper Storage After Use to Avoid Hidden Risks

✨Vertically Hang the Welding Gun for Storage

After use, the welding gun should be stored vertically rather than being placed flat on the ground or a workbench. Horizontal placement may lead to dust and metal debris settling on the optical components. Even small particles in the air can cause lens contamination, resulting in energy density abnormalities that lead to "lens burn" failures. After each operation, the scale tube should be wiped with a lint-free tissue soaked in anhydrous ethanol, following a single direction to clean off any welding slag or spatter. This prevents carbonization buildup at high temperatures during the next operation.
✨Neatly Coil Armored Cables – Never Pull or Drag
During or after welding, never pull or drag the armored cables or move the machine by its cables. The cables should be properly coiled and stored to prevent damage from compression, excessive bending, or stress concentration at joints, which could compromise the optical fiber, power line, or signal transmission stability.

Second  Routine Cleaning and Regular Maintenance

📢Scale Tube Cleaning
It is recommended to clean the scale tube every two days using tissue or clean cloth to remove welding residue and spatter, which helps maintain optical path quality and efficient heat dissipation.
📢Regular Filter Maintenance
Air filters in the cooling system or air inlets should be cleaned weekly, or more frequently depending on usage. This prevents dust buildup that can obstruct airflow and impair internal heat dissipation, ultimately extending component life.
Three Electrical Safety and Proper Connections

✅Separate Grounding for Laser Welding and TIG Welding Equipment
Laser hand held welding machines and TIG welders must use separate grounding systems. Sharing the same ground can cause electrical interference—especially from the high-frequency signals generated by TIG welding—which may affect the laser control system, disrupt pulse signals, and accelerate aging of the main control board components. This also reduces the risk of voltage fluctuations damaging the laser power supply, which could lead to system instability or even component failure.
✅Correct Handling and Movement
The laser welding machine for steel should only be moved by pushing its base or using proper lifting methods. Never drag the armored cable or control cables to relocate the machine, as this may loosen or damage internal wiring.
Fourth Do Not Overlook Environmental Factors
In environments with high dust or humidity, auxiliary protective measures—such as machine covers or dust shields—should be used.
When the equipment is not in use for an extended period, power it down completely, store it in a dry, well-ventilated space, and perform periodic power-on self-checks.

As a high-value precision tool, the stability and longevity of laser welding equipment depend on meticulous maintenance. Foster Laser remains committed to providing not only high-performance products but also comprehensive after-sales service and technical support. By following the above recommendations, customers can significantly extend the service life of their laser welding machines, reduce failure rates, and boost production efficiency.
