Optimizes arc ignition performance for hard‑to‑strike welding electrodes.
Adjustable to select optimal dynamic characteristics of welding arc.
Automatically lowers current for quick release when electrode sticks to workpiece.
Intelligent thermal protection prevents machine damage caused by overheating.
Efficient cooling system accelerates heat dissipation and extends service life.
Safeguards internal components against unstable input voltage surges.
Compact lightweight structure, easy to carry and suitable for outdoor operation.
Low idle power consumption, improves energy efficiency during long working hours.
Power Features:These fan-cooled, 2PCB IGBT inverter power sources automatically provide optimal start and stop parameters based on the set welding current.
MMA Welding:A wide current range makes these DC machines suitable for general purpose, stainless steel, and cellulosic electrodes.
Hot Start:Hot Start provides temporary current boost to significantly improve arc striking even with the most difficult electrodes.
ARC FORCE:Arc Force allows operators to choose the best arc dynamic characteristics for superior welding control.
ANTI-STICK:Anti-Stick automatically reduces the current so the electrode can be easily removed if it sticks to the workpiece.
TIG Welding:These DC Arc machines enable precise TIG welding on mild steel or stainless steel using an optional gas-valve torch.
VRD (Voltage Reduction Device):VRD safely reduces the open-circuit voltage during idle periods to protect the operator until welding commences.
