ARCCAPTAIN TIG Welder AC/DC 200A – 7-in-1 Multi-Process with Pulse (110V/220V)

Meet the ARCCAPTAIN TIG Welder AC/DC 200A with Pulse — a versatile 7-in-1 multi-process powerhouse designed for DIYers and pros working with aluminum, steel, copper, and more. Its range of modes and intuitive controls opens up project possibilities from delicate aluminum panels to robust steel assemblies, all in a compact, portable package.

7-in-1 welding versatility

This unit handles DC TIG, DC Pulse TIG, AC TIG, AC Pulse TIG, AC Pulse TIG Square, AC Pulse TIG Triangular, Stick (MMA), and Spot welding. AC TIG modes are optimized for aluminum and other non-ferrous metals, while DC TIG provides precise heat control for ferrous materials.

• AC TIG for finesse aluminum welding and oxide removal
• DC TIG for precise heat control on stainless steel, carbon steel, and copper
• Stick/Spot for strong joints on thicker sections
• Square/Triangular pulses reduce heat input and warp for delicate or tight-tolerance parts

Display, control, and precision

The machine features a large LED display for clear monitoring and adjustment of welding parameters. You can set Pre-flow, Initial current, Up-slope, Peak current, Base current, Down-slope, Crater current, Post-flow, Pulse duty, AC frequency, AC balance, and Pulse frequency. The 2T/4T/Spot TIG torch modes and optional foot pedal (not included) support varied workflows.

• 0.5 mm – 5 mm aluminum and 0.5 mm – 10 mm steel capacity
• 2T/4T/Spot welding torch control for different welding styles

Reliability and portability

Powered by an MCU digital control system and IGBT-based design, the ARCCAPTAIN TIG Welder maintains stable output while staying relatively light at about 12 kg. It is designed for easy transport and on-site work and supports both 110V and 220V inputs for flexible power options. A five-year quality service commitment backs the product, reflecting the brand's support and confidence in long-term use.

In practical terms, you might tackle automotive panels, bike frames, aluminum scaffolding, or repair joints on non-ferrous components. The combination of precise control, programmable parameters, and diverse waveform options helps you explore different welding approaches with less guesswork. While outcomes depend on technique, material condition, and setup, many users find the 7-in-1 design expands what you can attempt in a single session.
