The MMA-250FI Gives you Röhr Quality Exceed your Expectations
Röhr welders are built to last with high quality components that will ensure reliability for occasional or regular users. This welder uses the latest inverter technologies to dramatically reduce overall footprint. Inverters dramatically reduce the power required to weld by increasing efficiency by 30% and they produce a consistent power supply giving you the most stable welding arc. IGBT monotubing significantly increases efficiency compared to normal MOS tubing. Perfect for a Wide Variety of Welding
This welder is multi-use so you can weld stainless steel, carbon steel, copper, alloys and other coloured metals.
The Latest IGBT Technology
IGBT is a bipolar transistor with an insulated gate electrode. This semi-conducting device is being increasingly used in power electronics because it combines the advantages of two transistor types: the easy controls of the field effect transistor and the fast switching and high breakdown voltage of the bipolar transistor. The IGBT also offers some robustness against short circuits because it limits the electrical continuity.
Featuring ARC Force and Hot Start
With ARC Force, the current increases automatically when the arc is shorter. Hot Start automatically boosts the tension at the ignition of the arc, this function facilitates the electrical arc ignition. After ignition, the unit automatically returns to the pre-set voltage.
MMA Arc Welding
MMA is electrode welding with a coated electrode.
This function helps to prevent overheating of the electrode by switching off the welding current when the electrode sticks to the material.
