TIG 250PAC/DC DSP
TIG/MMA Welder
- Built with mature MOSFET 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 process requirements.
- Adjustable start current, peak current, and base current help improve arc control and welding performance.
- Adjustable up-slope and down-slope time support smoother weld starting and finishing.
- Adjustable pulse frequency helps create different weld bead appearances for specific welding requirements.
- Pulse duty cycle is adjustable from 10% to 90%, cleaning width is adjustable from 20% to 80%, and post-flow gas time is adjustable from 0 to 10 seconds, giving operators flexible control over the welding process.
- AC cleaning control helps remove the oxide layer on aluminum surfaces while balancing penetration and tungsten electrode consumption.
- Built-in overheating, overcurrent, and overvoltage protection, combined with Class F insulation, supports stable and safe operation.
