Double reverse star style main circuit, T-reactor. Optimize direct current T-reactor, so that is works steady whatever low current and high current, not much splash, and good looking joint.
Slowly wire feed when generating of arc, preset welding wire diameter, welding current, matching the welding specification automatically. Easy operate.
Compensate automatically, fit electricity grid wave. Fill the arc pit automatically when end welding. Still work steady when the output electric line is 50M.
Surface is acidized, phosphated, static blasting painted. Paint film is glabrous, solid, corrosion resistant and never break off.
