Troubleshooting Guide
IssueLikely CauseSolution
Machine Does Not Power On: No mains power, blown fuse, faulty switch: Check supply, reset breaker, test switch
No Laser Output: Interlock not engaged, dirty lens, wrong settings: Check interlocks, clean lens, reset parameters
Weak or Unstable Arc: Low power, dirty workpiece, poor grounding: Increase power, clean metal, secure clamp
Plasma Torch Won’t Ignite: Low air pressure, worn tip, bad trigger: Ensure 4.5–6 bar pressure, replace parts, check trigger wiring
Excessive Dross (Plasma): Wrong speed, worn tip, bad air pressure: Adjust speed, replace tip, reset pressure
Machine Overheating: Duty cycle exceeded, clogged vents: Let cool, observe duty cycle, clean vents

Quick Tips & Notes
EWELDL150 is ideal for thinner material and light fabrication
EWELDL200 offers higher output for thicker jobs and longer duty cycles
Keep torch angle between 5–15° and maintain steady hand movement
Clean work surfaces before every weld
Replace consumables regularly for consistent results
Frequently Asked Questions (FAQ)
What materials can the laser welder handle?
It is compatible with carbon steel, stainless steel, aluminium, and galvanized steel.
Does it support both continuous and pulsed modes?
Yes, it supports both continuous wave and modulated (pulsed) operation for versatility.
What shielding gases should be used?
Pure argon or nitrogen depending on the material being welded.
How fast does it weld compared to traditional methods?
Welding speed is 3–5 times faster with up to 35% electro-optical conversion efficiency.
What is the max thickness it can weld?
Up to 4 mm on carbon steel and stainless steel; 3 mm on aluminium with the 1500 W version.
What safety features are built-in?
Includes a ground clamp interlock—laser only fires when the clamp is connected and the gun is triggered.
What maintenance is required?
Replace the protective lens monthly and copper nozzle every 3–5 months, depending on use.
Can it be used for all weld joints?
Yes, suitable for butt, lap, and corner welds.
Is it safe for 24-hour operation?
Yes, the machine supports continuous use for industrial applications.
