- Modern inverter technology
- WIG welding with LIFT ignition
- Suitable for use on generators e.g. in workshops, schools, metal construction, on construction sites or for farmers
- Hot Start: By temporarily increasing the welding current, the arc ignites safely and is immediately stable
- Anti Stick: If the electrode accidentally sticks, the welding current is automatically reduced and thus an annealing of the electrode is prevented
- Arc Force control: Internal monitoring of welding current and voltage quickly and safely resolves short circuits. The adjustable increase of the current stabilises the arc and the electrode can be processed without problems.
- VRD (Volt Reduction Device): voltage reduction in open circuit 
You will receive the 3-year Stürmer warranty for this item when you register online.
 
- Hot start for safe and stable ignition of the arc
- Anti Stick against annealing electrode when bonding
- Arc-Force resolves short circuits safely and quickly
