Precisely controlled welding time, difficult deformation faded light gauge welding. The heat affected area is small. There is no heat input during the instant of stacking, so there is no deformation, undercut and residual stress. Local annealing will not occur and no reheating is required after repair. Low noiseWith silent fan, and environmentally friendly panel. The cold welder fuses the special welding integrated plasma cutter with up to 10 mm cutting power, separates almost all conductive materials such as steel, copper, stainless steel, brass, aluminum, titanium and many more. Multi-purpose machine: It can perform surfacing, surface strengthening and other functions. The required weld overlay and strengthened thickness and finish can be obtained by adjusting the discharge power and frequency., Manufacturer: QAXRZCUCD
