STAHLWERK welder MIG MAG 270 ST IGBT- Inert gas welder with synergic wire feed and real 270 amps / MIG/MAG welder, E-Hand, MMA

The STAHLWERK MIG-270 ST gas shielded welder works with up to 270 amps and is suitable for MIG/MAG welding as well as for E-Hand/MMA welding. The MIG 270 ST offers many advantages. In addition to smart cooling with integrated overheating protection, the welder has a synergic wire feed. The speed of the wire feed is automatically controlled by the set welding current. A 4-roller drive ensures a reliable and powerful feed, which also continuously and safely feeds thicker welding wires during MIG/MAG welding. Despite the extensive functions, the MIG-270 ST has a compact design and works powerfully and reliably thanks to advanced IGBT technology. In addition to a comprehensive accessories package, the MIG 270 ST - like all STAHLWERK units - comes with a 7-year warranty.

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. 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 conveniently from the unit with the red wire feed button when the hose package is laid out.
  • 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.
