Welding Gun

Portable AC Spot Welding Gun


Application: welding manufacturing of automobile & rail transit vehicle industry


Energy saving: the transformer and welding guns are directly integrated, eliminating the consumption of water cable, thus greatly saving energy (72.5% relative energy saving)

Easy to operate: with bearing disc hanging device, it can move and weld in any direction in X, y and Z, which is convenient and light

Great variety of goods: can be customized according to user needs to meet the needs of different stations, different thicknesses and different processes

Small size: reducing the volume by 75% and the weight by 80%
