The tail of the integrated suspension spot welding tongs adopts a lightweight structure design, the cylinder pressure output is stable, the body is small in size and light in weight. The transformer is in the form of power frequency, which is used in the work stations with complex operating posture and high turnover frequency of the welding tongs. Due to the small size of the welding tongs, the welding pressure and power are limited, and they are generally used for thin plate welding.
1. High efficiency Resistance Welding Machine.
2. Easy to install and simple to operate, saves energy.
3. Nimble and 360° rotational use.
4. Small, light, high power output.
5. Electrode and welding arm are all water cooled.
6. Gun body is cast with special aluminum.
7. The electrode arm is made of copper alloy with good flexional strength, high conductivity.
8. High production rate.
