The EWM Wega 400 A is a MIG/MAG welder of transformer design, supplied from a 400 V mains, liquid cooled. The current reaches 400 A and the interconnection cable is 10 m long.
What this machine is for
This is kit for a fixed station in a fabrication workshop, where mild steel goes through with solid wire. You set the welding voltage in steps with switches and you control the wire feed steplessly, so you choose the parameters yourself, without synergic programs. The operation is simple, but the choice of settings stays with the welder.
Transformer design means a simple circuit and copper windings, which the description points out. Machines of this type have less electronics that can be damaged. The 10 m interconnection cable moves the feeder away from the source, so you walk with it around the structure and the machine stays in one place. A liquid cooled torch stands up to longer runs without breaks for the equipment to cool.
Features and equipment
- Transformer design with copper windings.
- Stepless control of the wire feed.
- Stepped control of the welding voltage.
- Interconnection cable of 10 m between the source and the feeder.
- Liquid cooling, water cooled torch.

What to watch out for
The transformer weighs its own, so the machine suits moving around the hall and not carrying between building sites. The 400 V supply needs a three phase socket, and the draw at start up is higher than in inverter sources, so agree the installation with an electrician. Stepped voltage control gives fixed steps with no settings in between, and you have to take that into account on thin sheet.
With liquid cooling watch the coolant level and the flow through the hoses, because a lack of flow ends with the torch overheating. The description says that the machine was in working order and ready for use, with no earlier work inside it, but it does not list a torch or an earth cable, so confirm what the set holds before you buy. The description gives no weight and no dimensions.
