* Unique auxiliary balancing DC reactor makes smooth arc and realize high speed welding. * Solid Core /Flux Core and Arc selection function * Line voltage compensation keeps welding parameters constant even when input voltages change ± 10%. * Cooling system operates only when needed. Reduces excess noise and contaminants drawn into the machine. * Thermal overload protection automatically shuts down the system to prevent High repair costs. * One-knob adjustable function. * Power efficiency, the machine automatically shut Of for more than 4 minutes stand by. * Digital meter for presetting or monitor welding voltage or Amperage. * Superior welding and reducing spatter.
