MT200-ACDC

CK Worldwide MT200-AC/DC Compact AC/DC TIG Welder

The CK Worldwide MT200-AC/DC is a compact professional AC/DC TIG welding system designed for both precision fabrication and light industrial production work. It combines dual-voltage capability (110V / 220V) with a high-frequency arc start, pulse control, and square-wave AC output, making it suitable for welding aluminum, stainless steel, and mild steel.

Built for portability and performance, this unit is commonly used by fabricators, maintenance technicians, and advanced hobby welders who need a machine that balances power, control, and compact size.

Source specifications confirm it delivers up to 200A output on 220V, with advanced TIG functions such as AC frequency adjustment, pulse frequency control, and post-flow gas control.

Key Features

- Dual-voltage (110V / 220V) flexibility
- AC/DC TIG capability (aluminum + stainless steel ready)
- High-frequency arc start for precise ignition
- Adjustable AC frequency for aluminum control
- Pulse TIG mode for heat-sensitive work
- Compact and portable 32 lb design
