MR400 DC Arc Welding Machine OTC
Stable Arc
- Stable and smooth arc by constant current characteristics.
Heavy Duty Cycle
- Especially suitable for medium and thick plate welding (Ratedd duty cycle 60%)
Safety Design
- Using strong materials for cases, the chassis mechanism does not allow small animmals into the power supply unit
Arc Drive Control
- Prevents electrode sticking to base metal during welding. (Standard Device)
Diversified Applications
- Useful for wide range of applications such as pressure tank, construction and on site work.
Features
