Device Funktions & Components
- MIG/MAG – Metal arc gas welding with direct current (DC). You can weld with inactive / inert (MIG, e.g., argon) or active (MAG, e.g., CO2) gases. Gas and welding wire come from a torch head and allow the work to be carried out with just one hand.
- Synergic wire feed: The welding current controls the wire feed speed entirely in accordance with the welding current.
- 2 in 1 combined device – MIG/MAG & MMA welding with up to 270 A.
- IGBT Technology – latest transistor technology enables highest power and a duty cycle of 60 % at full power. No transformer, no MOSFET, modern IGBT.
- Lightweight & compact design – only 16,6 kg and dimensions of 590 x 220 x 590 mm. Innovative IGBT transistors save space and weight compared to the old MOSFET technology. No heavy carrying!
Device Features & Benefits
- Highest efficiency & performance – Three phase current (400 V) supplies the device and allows an output power of real 270 amperes.
- Smart cooling & overheating protection – modern technology, built-in overheat protection and high-performance cooling allow you to get maximum Performance.
- Automatic wire feed– the wire feed speed is automatically controlled by the set welding current.
- Inductance – infinitely adjustable chocke, which smooths the welding current and improves the welding quality and ignition properties.
- 4 wire drive - reliable and powerful wire feed. Thanks to 4 drive rollers, even thicker wires are continuously and safely conveyed.

- Voltage – Variable voltage control to manually adjust the burn-in and burn-off of the wire, so the different properties of different materials can be taken into account.
- Manual wire thrust – no loss of gas or tedious pushing-through of the wire any more. If a new wire roll is to be fed through the hose package, this is done completely automatically with the wire feed button.
- Wire spool – commonly available 5 kg to 15 kg wire rolls can be processed here. The spool can accommodate 50 mm spools.
- Wire drive reel – different wire thicknesses can be used by simply changing the drive roller from 0.8mm to 1.0mm.
- MMA / Stick electrode welding– is a universal welding process.
- Note: The unit is not intended for use in residential areas where power is supplied by a public low-voltage power supply system. It may be difficult to ensure electromagnetic compatibility in these areas due to both conducted and radiated interference.
