Mag Arc Welding Machine is incorporated with a magnetic switch in the main transformer to ensure less power consumption under no load conditions. The Arc Welding Machine is provided with I.C and Thyristor control circuit that maintains stable output under adverse input fluctuation and enables gradual smooth current setting. The Arc Welding Machine is offered with a reactor, which improves arc start and reduces spatters considerably. Mag Arc Welding Machine is available in a compact and lightweight design that facilitates ease of usage.
