Feature
1. The water pump welder is equipped with 60KJ capacitor discharge welding technology.
2. The welding system requires manual feeding and discharging of the workpieces.

Background information
The welding machine is designed for 1 inch nut water pump housings. The traditional technology used for this process is argon tungsten-arc welding, which has a low efficiency and high labor cost. Our resistance welding technology significantly improves production efficiency and quality.
