DTN1-25KW metal shell pneumatic spot welding machine

The DTN1-25KW metal shell pneumatic spot welding machine adopts microcomputer control and LCD display parameters, which is accurate, intuitive and convenient. When welding, the sparks are small and the welding is firm. Suitable for welding of hot and cold plates, stainless steel plates, stainless steel wires, nuts and other workpieces. The welding machine is equipped with an all-copper transformer and wide-voltage technology. The voltage can be automatically adjusted up and down by 20%. When used normally, the operation is simple. Pressure time, welding current, welding time, maintenance time and rest time can all be completed on the microcomputer controller. adjust.
