What Is igbt on welding machines Inverter Welders

These days IGBT on welding machines reffers to the type of transistors used in the inverter matrix that is at the heart of the inverter welding machines operation. Insulated Gate Bipolar Transistors can be manufactured to operate at any current as opposed to MOSFET types that are limited to 20/30 amps. As a result IGBT transistors do not need to be connected in parallel which can increase reliability dramatically. IGBT welding machines are the new favourite amongst welding engineers and welders tradespeople although these days there is not much difference […]

Why do you need to use AC for Tig welding aluminium

The question of asked is, why do you need to use AC for Tig welding aluminium?

Electrons need to flow welding work piece to welding tungsten in order to remove aluminium oxide. Excess workpiece to welding tungsten electron flow builds heat at the tungsten tip therefore alternating this process enables the oxide to be removed and heat to build at the job for penetration. A balance control can therefore give more cleaning or more job penetration by adjusting balance to be more positive or more negative.
