Mitec 400A TIG & MMA Inverter Welding Machine 380V – MI-TIG400A

Description:

The Mitec 400A TIG & MMA Inverter Welding Machine 380V MI-TIG400A is a three-phase 380V inverter dual-process welding machine supporting TIG (10400A) and MMA welding, with 67V no-load voltage, TIG and MMA duty cycle 400A at 60% / 310A at 100%, IP21S protection, Class F insulation and 0.93 power factor. Suitable for demanding workshop and industrial fabrication where TIG precision and MMA versatility are both required.

Key Features:

• TIG mode supports controlled, precise welding while MMA mode broadens application flexibility.
• Separate TIG and MMA ratings make process selection clearer.
• 400A output supports demanding three-phase fabrication work.
• Air-cooled inverter construction supports heat management during operation.
• IP21S protection, Class F insulation and 0.93 power factor are confirmed on the rating plate.
