Solder resist type weld the special-purpose equipment alternately. It can weld wire diameter 2.0~3.5mm

DH25-Spot welder

    It uses SCR trigger system instead of AC contact point for cost saving. The max wire diameter is Φ3.5+Φ3.5. The solder joint is fix without annealing. The welding head no need for cooling water. Multi-range of welding current and dual-directional regulation of welding time to fit different kinds of wire diameter. The advanced design of circuit saves electricity. Also, it can be used for overlaying welding.
