Inverter Based Welding Rectifiers are used when you desire DC output to melt your electrode. Rectifiers themselves are capable of high performance current deliveries in power sources as little as 160 amps to a massive 1200 amps. The diode based was replaced by thyristor controls that were superseded by advanced electronics – IGBT. This technology revised, restudied and improved several times over the last few years and has allowed us to create a design so robust – it’s like the confidence of knowing that you can take the most abusive welding application head on.
