The Tecna 2kVA Spot Welding gun is a single phase hand operated spot welder suitable for body shop operations.  Supplied as a kit in a case with 125mm and 500mm arms as well as a pair of cranked electrodes. 125mm arms perfect when more pressure is required between the electrodes and 500mm arms for increased throat depth, when reach is required too.

With a 2kVA output, this gun is suited to professional applications, being semi-automatic and suitable for up to 2mm + 2mm body shop situations.

Providing 2kVA at 50% duty cycle, this portable spot welder features an electric timer, high pressure (minimum force) handle and a heavy duty “class F” transformer.
