Advantages

1. The welding current is DC. When there are inductive/magnetic materials in the secondary winding, the welding will not be affected;

2. The three-phase power supply is more adaptable to the fluctuation and voltage drop of the power grid;

3. The process is more reliable, and DC welding will be better for most of the metals with resistance welding;

4. Reduce operation cost, including saving welding energy at each point and shortening welding cycle;

Main Structure and Fixture of the Equipment

The multi head spot welder is mainly composed of the equipment host, upper and lower electrode components, fixture components, welding controller, PLC controller, touch screen components, water and gas circuit components, etc.

Welding May Cause Fire and Explosion

When welding closed containers, such as tanks, boxes, pipes, and other workpieces, they may explode. The sparks generated by the arc during welding will splatter everywhere. Splashing sparks, hot workpieces, and heating equipment can cause fires and combustion. Unexpected contact between electrodes and metal objects, poor connection of welding cables, and poor contact of the current path on the welding substrate side can all cause sparks, overheating, explosions, and fires. Before welding, attention should be paid to inspecting and ensuring the safety of the working area.
