♦ Distance,angle and length of welding arm can be made according to customers' requests.
Resistance welding principle:
When two electrodes are pressed into the workpiece, the two metal layers form a contact spot welder resistance under the pressure of the two electrodes. When the welding current flows from one electrode to the other electrode, the two contact resistance points form instant thermal fusion, and the welding current flows from the other electrode to the two workpieces, forming a circuit instantly, which will not cause harm to the two electrodes.
Features:
1. The portable spot welding machine is fully enclosed with plastic case, so it’s much safer for worker to use
2. The portable spot welding machine is adapt to the thickness of workpiece plate when working
3. High productivity and can provide adequate supply of components and parts
4. High control precision, stable output current, little influence of inductive reactance and little splash
