Applicable in welding carbon steel, stainless steel, nickel alloy, and various acidic and alkaline electrodes.
Multi-purpose model, capable of welding root cleaning and welding repair;
High arc energy, fast and high-quality gouging;
Full series support carbon arc gouging function and ST2-630 can gouge carbon rod up to 12mm.
1)Remote Control Adjustment Function
One-touch switching between main machine and remote control module;
Common parameters are able to be regulated such as welding current and arc force current;
Especially suitable for long-distance, high-altitude, or narrow-space operations. It eliminates time-consuming task of "walk, adjust, return to weld," and improve working efficiency.
2)Available with Wired or Wireless Remote Control Module
Wired remote control module: Equipped with a seven-pin control cable for stable signal transmission and shielded communication cable for strong anti-interference capability, could be used in complex working condition;
Wireless remote control module: Wireless mobility is more convenient, and signal transmission via power cable allows for communication distances up to 100 meters.
Equipped with VRD (Vibration Reduction Device) anti-electric shock protection function
VRD is 15V, effectively reducing the risk of electric shock for welders and protecting their safety.
