GYS PROMIG 400-4S DUO DV MIG/MAG 焊接机 (230/400V, 3ph, 40-350 A, steel torch 4m)

Three phase «Synergic» 350 Amp MIG welder with 4 drive rollers. Ideal for maintenance and industrial production work. Increase productivity - With two individual wire feeders it enables two different wire types/sizes are fitted at the same time thus avoiding time consuming wire and gas bottle changes.


2 wire feeders: One located inside the power generator and one inside the separate wire feed unit with a 10 m connection cable.

2 torches: Automatic selection of the internal or external wire feeder and welding para meters (including gas type) upon pressing the trigger.

2 gas controls: Two solenoid valves enable different gas types to be selected just by pressing the trigger e.g Argon for aluminium used with the main machine and Argon/CO2 for steel on the separate wire feed unit.

2x faster : Eliminates the need to change MIG tips, drive rollers, torch liner and MIG wire reels when changing jobs.

2x more versatile: One machine can be setup to weld Steel/Aluminium, Steel/ Stainless or Aluminium/Stainless.


GYS experience integrated in more than 1000 parameters managed by microprocessor.

- Synergic mode : Optimum results without adjusting the wire speed :

• Select wire type

• Select wire size

• Select the power (refer to table on the front of the machine)

- Manual mode : Manual adjustement option of the wire speed and power
