With the increase of electrode pressure, the spot welder's R decreases significantly

clean the surface of the weldment. Spot welders have upper and lower limits for the current and time required for metals with different properties and thicknesses. ---Zhongbang Welding Machine

There are those things about spot welders:As we all know, spot welders use electric energy, which can instantly convert electric energy into heat.

Biomass energy is an important energy source in the 21st century. It is bound to be paid more and more attention by people. Has a very important meaning.

Zhongbang Welding Machine even said that there is a "spot welding step" about the spot welding machine. Apply pressure between the electrodes.
