Lightwelder20 Portable Laser

LIGHTWELDER20 PORTABLE LASER

The most powerful portable laser welder on the market.

5 TIMES FASTER THAN TIG!

Laser welding is a revolutionary process. 5 times the speed of TIG, but with ¼ the distortion and heat input. It requires low skill levels and is a semi automated process when using our wire feed system for speed control. Perfect welds become fast and easy.

2kW VERSION – POWER TO RULE THEM ALL

Having an extra 33% more power allows welding up 6mm with full penetration in one pass, far quicker and with far less distortion than MIG or TIG.
Nothing beats Lightwelder20. 33% more power than the others, yet still far cheaper. Truly unbeatable value and capabilities. Lightwelder20 is the latest generation in laser welders, with very high efficiency and cooling via a refrigerant heat pump. This makes it truly portable, reduces maintenance, AND saves on argon and electricity bills compared to TIG. Aluminum welding is a key strength due to our high power and high power density which are only matched by welders costing twice as much

UNBEATEN EFFICIENCY, VALUE AND WELDING SPEED

Our portable laser welder, Lightwelder20, has 2000 Watts of output power. It is very similar to the well-known, more expensive competitor, but our laser output has higher power AND higher power density than their standard and mid range models. This allows us to weld aluminum twice as fast, while costing far less.
Lightwelder20’s class leading efficiency means less power consumption, and less heat buildup. This avoids overheating and the premature aging that others can experience. Duty cycle is not a problem, with 100% duty cycle at 40°C. High efficiency also means it consumes less than 24 Amps at 220V AC, as measured with a current clamp.
Competing air cooled laser welders use an inferior cooling technology (heat pipes or simple convection) and suffer from a reduced duty cycle in hot weather.

SAFETY NOTES

1. Laser welders are Class IV lasers. They can start fires and burn skin at close range but are also dangerous to the eyes for at least 100 metres, so special safety measures are required. We provide guidance on safety, but because safety is so important our safety acknowledgement must be signed before shipping and using the laser welder.
2. You must purchase and use our safety glasses and laser welding helmet with this machine. In any case these are the best value on the market, with high and known protection levels, so you should be using them anyway.
