Stahlwerk MTM200 ST 3-in-1 Gas-Shielded Welding Machine – TIG, MIG/MAG, MMA, FLUX, CuSi3 soldering

IGBT technology: Modern inverter technology with high efficiency, stable arc and compact design.

Hotstart function (MMA): Automatic voltage increase when igniting the electrode for better ignition results and a quickly heated seam start.

Smart cooling & overheating protection – State-of-the-art technology, integrated overheating protection and high-performance cooling enable maximum power to be called up. A powerful fan ensures that the maximum duty cycle is utilized thanks to excellent cooling.

ST-Guard housing: Ergonomic, robust and reliable housing with easily accessible, intuitive front panel.
Infinitely adjustable welding current: Adjustment of the welding current to the material type and thickness for optimum seam quality.

VRD (Voltage Reduction Device). Manual switching on/off of the VRD function enables the output voltage of the welding machine to be reduced to a safe level to protect the operator when touching the electrode while welding is not in progress.

Automatic wire feed speed. (Automatic wire feed) – The welding wire is automatically untwisted from the spool and pushed by the wire feed unit through a hose package several meters long to the contact tip in the torch. The speed is self-regulating, depending on the welding current.

Test and inspection modes: Two test and inspection buttons can be used to check both the wire feed and the gas supply. By pressing the wire feed test button, the wire feed can be checked manually without starting a welding process. This activates the wire motor so that welding wire emerges from the torch tip, but without current and gas flow. This function is used to check the feed and to thread the wire into the torch, for example after a wire change. The gas check button is used to manually switch on the gas flow without starting a welding process: A solenoid valve opens and shielding gas flows out of the gas nozzle. This function is used to check the gas supply, to check for leaks and to set the gas volume on the flow meter.
