INVERTER TYPE SPOT WELDERS – PROSPOT I4


We have been using traditional technology of transformer type spot welding machines till now but with the introduction of new generation high strength steel it has become difficult to weld as transformer type spot welder do not have sufficient welding power and the duty cycle is also low which results in overheating and affects the quality of weld.

The global automotive aftermarket Body shops have now moved to the next generation inverter type spot welders which are needed to efficiently weld the new generation steel as these Inverter type spot welder have high welding power with low power consumption.

These inverter type spot welders can also effectively weld the normal steels.

Model: Spot Welder i4
