ARCPEX 200A AC/DC TIG Aluminum Welder with MIX TIG, 5-IN-1 220V Professional Pulse TIG/Stick Welder, 60% Duty Cycle, 100% Copper Accessories, Easy-Setting MCU & 12-Pin Foot Pedal for Pro Fabrication
The ARCPEX TIG200P is a professional-grade 200A 5-IN-1 AC/DC MIX TIG welder built for welders who demand precision on aluminum, steel, stainless, titanium, and exotic alloys. Featuring exclusive MIX TIG technology, Easy-Setting MCU with Auto-Memory, 12-pin foot pedal interface, and 100% pure copper accessories — professional performance made accessible.
MIX TIG automatically alternates between AC and DC current, delivering deep penetration + oxide cleaning simultaneously on 1/4" aluminum plates. Achieve X-ray quality stack-of-dimes beads that standard AC-only or DC-only welders cannot produce.
💾 EASY-SETTING MCU — Auto-Memory for Beginners
The MCU Digital Interface simplifies complex settings with a high-contrast display. The Auto-Memory Function saves your successful parameters — find your perfect settings once, and the machine remembers them forever. No more re-dialing every session.
🪤 100% PURE COPPER — Not CCA
Includes a 100% Pure Copper 300A Earth Clamp and 200A Electrode Holder. Pure copper promotes a more stable, softer arc that is easier to strike and maintain — especially important for beginners. Outperforms cheap CCA cables for safer, long-duration welding.
🔥 60% DUTY CYCLE — Built for the Workshop
60% Duty Cycle @ 200A (25°C) and 40% @ 40°C. This industrial-grade thermal efficiency, powered by stable 220V input, allows for extended work sessions on heavy-duty car restorations, farm repairs, and fabrication runs without overheating interruptions.
🎯 HF START — Zero Tungsten Contamination
High-Frequency arc initiation starts the arc without touching tungsten to the workpiece — eliminating contamination and producing consistent professional-quality welds from the first strike. Essential for clean aluminum TIG work.
🦶 12-PIN FOOT PEDAL — Zero-Interference Control
The 12-pin professional remote socket promotes zero-interference signal transmission — far superior to common 5-pin connectors. Enables ultra-smooth, real-time amperage adjustment for precise puddle control on thin 1mm stainless steel and aerospace components.
