RÖHR MIG-250FI - MIG Welder Inverter IGBT 240V / 250 amp DC Gas Flux Wire Welding Machine

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.

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.

This function helps to prevent overheating of the electrode by switching off the welding current when the electrode sticks to the material.

This unit features a stepless wire feed system so you can focus all of your attention on your weld. Also it's highly portable design allows for use wherever you need it.

IG is used for welding materials such as magnesium, copper and other non-ferrous materials and their alloys. MAG on the other hand, is suitable for steel, structural steel and most of its alloys. Thus, great welding seams can be briskly and efficiently manufactured with different thicknesses, ensuring that material distortion is kept to a minimum.

MIG/MAG welding require a protective gas. Inert gases, such as argon and helium, as well as active gases (for example carbon dioxide) and other mixtures can be used. The solenoid valve regulates the flow of gas. The valve is operated via a button on the torch.

This welder does not need a specialist power supply, it can run straight off the mains.

Easy to plug in anywhere and a simple on / off switch to get started.
