The TIG-400P ACDC, TIG-350P ACDC-W, and TIG-400P ACDC-W deliver versatile AC/DC TIG and MMA welding for steel, stainless, and aluminum. Featuring sine/triangle/square waveforms, precise pulse control (DC: 0.2–500Hz, AC: 0.2–200Hz), and torch modes (2T/4T/4T2/SPOT), these inverters optimize bead quality and heat management. Industrial durability (60% duty cycle, IP21S/F-class insulation) pairs with parameter memory, 6-pin amperage pedal control, and air/water cooling for demanding workshop reliability.
Advantages
Key Features
Inverter-based TIG series using 20-30kHz IGBT tech; compact, energy-saving. Multifunctional: WSM, DC TIG, pulsed TIG. Precise slow-start/decay control; superior arc stiffness & HF ignition success.
System Specs
60% duty cycle at max output; constant current characteristic. Exceeding cycle risks overheating and damage.
Setup Rules
Avoid dust/metal powder, corrosive gas. Op. temp: -10°C~40°C; storage/transit: -25°C~55°C. Max 15° tilt. Dry & ventilated (<90% RH), no sun/rain. Windshield weld zone. ≥20cm wall clearance; ≥30cm machine spacing.
