PAW LHM Series |
IGBT Plasma Welding Machine
|
|
|
|
 Applied for precision welding, high-speed welding, metal remelting, surfacing, hot spray for low carbon steel, high alloy steel, low alloy steel, stainless steel, copper, aluminum, nickel, titanium, molybdenum, tungsten, palladium, rhodium and their alloys.
Suitable for tiny-beam PAW, melting PAW, small-hole PAW, TIG, MMA, etc.
LHM-500 can be used for CAGC.
High welding efficiency, high speed as three to ten times than TIG welding. |
