TIG 400PAC/DC DIGITAL
AC/DC TIG/MMA Welder
- Built with mature IGBT inverter technology.
- Multi-process design supports TIG and MMA stick welding.
- Adjustable welding current and post-flow gas time provide better control over weld bead formation.
- 2T/4T trigger modes support different welding habits and application requirements.
- Adjustable start current, peak current, and base current help improve welding performance.
- Adjustable up-slope and down-slope time support smoother weld starting and finishing.
- Pulse frequency is adjustable from 0.5 to 10 Hz, allowing operators to set different weld bead characteristics for specific process requirements.
- Adjustable pulse duty cycle, pulse width, and post-flow gas time provide flexible control over the welding process.
- Built-in overheating, overcurrent, and overvoltage protection, combined with Class H insulation, supports stable operation in demanding industrial use.
