AC DC

Ultra-stable arc even at 5A–250A

Perfect weld bead on aluminum, stainless steel, copper alloys

Built-in HF start – no contact tungsten contamination

Foot pedal included for real-time current control in pipe fabrication

Pulse TIG Welder

The MASTERTIG-320CT supports AC TIG, DC TIG, Pulse TIG, MIX TIG and DC MMA processes. Advanced AC waveform control provides adjustable AC frequency, balance and amplitude, allowing welders to precisely control arc concentration, cleaning action, heat input and penetration.

The MASTERTIG-400CT is designed for light industiral which is 400A@60% Duty Cycle.

Slow thick-plate welding and fast tungsten consumption? The MASTERTIG-500CT's MIX TIG technology significantly reduces tungsten consumption while achieving deeper penetration and clean weld seams. 500A high current, 3-phase industrial power—ideal for pipe fabrication and heavy structural components.

The ALUTIG-250HD has full TIG functions including DC TIG, AC TIG(four AC wave shapes) and Unique MIX TIG processes.
