Important functions & device information at a glance

Device functions & components

  • MIG/MAG - Metal arc welding with direct current (DC). Welding can be done with inactive/inert (MIG, e.g. argon) or with active (MAG, e.g.CO2) gases. Gas and welding wire come from one torch head, allowing welding operations to be performed with only one hand.
  • Synergic wire feed: The wire feed speed is controlled fully automatically via the welding current.
  • 2 in 1 combination unit - MIG/MAG & MMA welding is possible up to 155 A.
  • IGBT Technology - Latest and most advanced transistor technology enables highest performance! No transformer, no MOSFET, most modern IGBT!
  • Lightweight & compact design - only 11.6 kg weight and dimensions of 450 x 240 x 370 mm. Innovative IGBT transistors save space and weight compared to old MOSFET technology. No more heavy carrying!
  • Attention - Bottle connection: W21.8 x 1/14" - Gas cylinders from the Netherlands and the UK may have a different connection! Please check the connections for compatibility before buying!

Device features & benefits

  • Highest Efficiency & Power - Single phase AC (230V) power supplies the unit and allows output power of true 155 amps.
  • Smart Cooling & Overheat Protection - State of the art technology, built-in overheat protection and high performance cooling allow maximum power to be retrieved.
  • Flux-Cored Wire - All of our ST Series units can use flux-cored wire. This allows welding without shielding gas.
  • Automatic wire feed - the speed of the wire feed is automatically controlled by the set welding current.
  • Inductance - continuously adjustable choke, which smoothes the welding current and improves the welding quality and ignition characteristics.
  • Current voltage (volts) - Variable voltage control to manually adjust the burn-in and burn-off of the wire. Thus, the different properties of a wide variety of materials can be acted upon.
  • Manual wire push-through - no more gas loss or tedious pushing of the wire through. If a new wire roll is to be fed through the hose package, this is done conveniently from the unit using the red wire feed button when the hose package is laid out.
  • Wire reel - Commercially available wire reels from 1kg to 5kg can be processed here. The spool mandrel can accommodate 16mm & 50mm spools.
  • Wire drive roller - by simply changing the drive roller from 0.6mm & 0.8mm & 1.0mm, different wire thicknesses can be used.
  • MMA electrode welding / MMA welding - is a universal welding process. No shielding gas is needed.
  • Note: The unit is not intended for use in residential areas where power is supplied by a public low-voltage power system. It may be difficult to ensure electromagnetic compatibility in these areas due to both conducted and radiated interference.
