Application

The series gas protection welding machine uses thyristor to control current output and input thread speed of welding machine. Adjustment of welding machine in series is smooth and stable. Welding machine is even and special, mainly used for welding CO2, MIG and MAG. Welding material includes: low alloy steel, high strength steel, stainless steel and aluminum, etc. Performance of welding machine is better, and welding machine has such function: emptily load, high voltage and slowly input thread, which make attract-arc power be over 95%. Without cable of remote control device, improving maneuverability, reduce break-thread trouble, having conversion enginery current and voltage respectively are adjusted or unified easily. Any beginner or specialized worker can use it with facility.
