Spot welding is not stable, how to adjust?
The power is sufficientAdjust welding time, welding current and pressure accordingly
The double point welding current welding principle, when the two electrode pressure workpiece makes two layers of metal forming some contact resistance in the two electrode pressure, welding current from the electrode through another electrode is formed on the two point contact resistance moment of welding, and the welding current from another the two part flow along the electrode with the electrode to form a loop, and is the internal structure of welders.
