MetaTig 400 ACDC

Features:

• AC/DC TIG (GTAW) + MMA (Stick) welding – versatile for aluminum, stainless steel, mild steel, and other alloys

• 400A maximum output current – suitable for medium to heavy-duty industrial TIG welding

• Advanced AC waveforms (Square, Sine, Triangular, Mixed) – allows optimized aluminum welding with better cleaning action and penetration

• Pulse TIG function – precise heat input control, reduces distortion, improves bead appearance

• High-frequency (HF) start and Lift-TIG ignition for easy arc striking

• Full digital control system – accurate setting of current, voltage, AC balance, frequency, and pulse parameters

• Job memory storage – save and recall welding programs quickly

• Excellent arc stability in both AC and DC modes, with low spatter and smooth weld beads

• Optional water-cooled TIG torch system for continuous high-current applications

• Built-in safety protections: over-voltage, under-voltage, overload, and overheat protection

• Robust industrial design with easy mobility (wheels + cylinder rack)
