The Migatronic Commander 400 is an inverter TIG power source with direct and alternating current and HF ignition. The maker gives 400 A at a 35% cycle and 295 A at continuous 100% work. The machine has pulse, and the set holds a Migatronic torch 8 m, an earth lead 3 m and a mains cable 3 m.
What this machine is for
With direct current you join mild steel and stainless steel, with alternating current aluminium, where the arc has to break the oxide layer first. HF ignition starts without touching the material with the electrode, so the tungsten stays clean. Pulse splits the heat input into pulses, so you hold the pool more easily on thin material.
A reserve of 295 A at a 100% cycle is a lot for a TIG source: the machine suits long welds on thicker parts. A torch 8 m long widens the reach around the structure, so you do not move the source at every change of position.
Features and equipment
- Inverter design: less weight and lower energy losses than in a transformer source.
- Direct and alternating current: steel and stainless steel on DC, aluminium and its alloys on AC.
- HF ignition: a contact free start with no contamination of the tungsten electrode.
- Welding current pulse: dosing of the heat on thin material and in forced positions.
- Duty cycle 400 A at 35% and 295 A at 100%: a current for continuous work.
- Torch 8 m long: reach around large structures without moving the source.

What you get

- Migatronic torch 8 m long
- earth lead 3 m long
- mains cable 3 m long
What to watch out for
The supply is 400 V. The product card gives liquid cooling, while the maker description does not say what kind of circuit it is, so confirm the configuration before you buy, because the choice of torch depends on it. The weight is not given, so arrange transport before collection. Look over the 8 m torch along its whole length, because that is where damage to the insulation shows up most often.
How we sell used machines
This unit was checked in our service workshop in Krotoszyn with measurements to PN-EN 60974-4 and a load test. The price includes the first year of the basic service package: an inspection with cleaning of the machine and a validation measurement. Further years can be added. We ship across the European Union, collection in person by appointment.
