PUWU 205Amp AC/DC Aluminum TIG Welder, 6-in-1 Multiprocess Welding Machine, AC TIG/DC TIG/AC Pulse/DC Pulse/MMA/STICK/SPOT TIG,110V/220V Dual Voltage, Square/Triangular Wave ACDC Welder Machine — Open-Box, 14% Off

6-in-1 TIG Welder：AC TIG, DC TIG, AC Pulse TIG, DC Pulse TIG, MMA/Stick and Spot TIG. From precision stainless steel TIG to heavy aluminum fabrication, it provides smooth, stable arcs and professional results across multiple materials.AC TIG is used in finesse welding various aluminum, magnesium alloys, and other metals. DC TIG provides low-temperature control. You need precise welding for various types of steel: stainless steel, carbon steel, copper.

Nine Different Waveforms：The welder has nine different waveforms more popular for DIYers.For general welding,sine wave and square wave are usually used.Triangular wave reduces the heat input effectively, so the weld forms rapidly. It is easy for thin metal welding.Different waves can be used for welding different metals such as carbon steel, stainless steel, copper, thin plate, alloy, magnesium and aluminum up to 1/4" (6 mm) and mild steel up to 3/8" (10 mm). Perfect for fabrication, repair, automotive, and workshop projects requiring clean, durable joints.

Smart Control & Operation：Features a high-frequency TIG start, adjustable pulse frequency, and digital parameter display for easy fine-tuning. Built-in Hot Start, Arc Force, VRD, and Anti-Interference systems ensure steady ignition, minimal spatter, and safer operation.

Dual Voltage & Safety System：It is a 110/220V dual Voltage welder for flexible use anywhere. Multi-layer safety design includes overheat/offload shutdown, Class-F insulation, and anti-static coating for extended machine life and operator protection.Compact and portable design—(18.3"×14.1"×8.6", 25.1lb)—makes it easy to move between worksites or store without taking up space.

Complete Accessory Package:Includes the PUWU PM-ACDC 205PRO welder, a 2m electrode holder with red 35-50 connector, a 2 m ground clamp with black 35-50 connector, a 3m WP-17 TIG torch, a 3m transparent mesh gas hose, an argon regulator, a foot pedal（only controls power on/off ）, 2 hose clamps, a welding mask, a steel brush, a U.S. power cord with conversion cable, and a PUWU instruction manual for easy setup and operation.

The PUWU PM-ACDC 205PRO is a 205Amp AC/DC Aluminum TIG Welder, 6-in-1 multiprocess TIG welder designed for precision, versatility, and reliability. It supports AC TIG, DC TIG, AC Pulse, DC Pulse, and MMA/Stick，Spot tig welding, allowing seamless transitions between aluminum, stainless steel, and carbon steel projects.Powered by advanced IGBT inverter technology, this welder ensures smooth arcs, deep penetration, and efficient power use. It can weld up to 1/4 inch (6 mm) aluminum and 3/8 inch (10mm) mild steel—ideal for automotive repair, metal fabrication, and industrial maintenance.The intuitive digital control panel offers precise parameter adjustments for current, pulse frequency, and gas timing. High-frequency TIG start enables clean ignition without contamination, while built-in Hot Start, Arc Force, VRD, and Anti-Interference features ensure stable performance and operator safety.With dual-voltage(110V/220V) capability, the machine automatically matches the input power for consistent output across different sites. Multi-layer protection systems—including overheat and overload shutdown, Class-F insulation, and anti-static coating—guarantee long-term durability.Despite its professional power, the PM-ACDC 205 PRO is compact and portable (18.3"×14.1"× 8.6", 25.1lb), making it easy to transport and store. Each unit comes with a complete accessory package, including TIG torch, foot pedal, argon regulator, electrode holder, ground clamp, and more — ready for use right out of the box.Professional, powerful, and precise — the PUWU PM-ACDC 205 PRO is your all-in-one solution for high-performance TIG and Stick welding on steel and aluminum.
