Funktions & Components
- MMA / Stick electrode welding - an universal welding process. An arc causes the electrode to melt, forming the weld. No protective gas is needed and can therefore be used flexibly anywhere.
- Expandable to a DC TIG welder with our optional WP-17V Universal Lift TIG Torch.
- IGBT Technology - latest transistor technology enables highest power at full power. No transformer, no MOSFET, modern IGBT.
- Lightweight & compact design - only 3,2 kg and dimensions of 245 x 100 x 160 mm. Innovative IGBT transistors save space and weight compared to the old MOSFET technology. No heavy carrying!
- Highest efficiency & performance - Single phase current (230 V) supplies the device and allows an output power of real 200 amperes.
- IGBT single board - The ARC 200 MD IGBT has an IGBT single board. Thanks to the compact design, welding units with a single board can be used very flexibly without having to forego the advantages of IGBT technology (high switching frequency, stable welding currents, thermal stability).
Device Features & Benefits
- Hotstart - Automatic voltage increase upon the start for better ignition results. Prevents the sticking of the stick electrode due to short-term superimposition of the set welding current and warms up the beginning of the weld faster.
- Anti-stick - Automatic shutdown of the welding current in case of sticking of the electrode which allows an easy removal. It also prevents annealing of the electrode.
- Smart cooling & overheating protection- modern technology, built-in overheat protection and high-performance cooling allow you to get maximum performance.
- 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.
