Hand Spot Welding Machine

Spot Welding machines use a method called resistance spot welding to join overlapping metals between two electrodes using electrical resistance. Squeezing the workpieces between the electrodes applies pressure, and the passage of welding current through the resistive metals generates heat.A spot welding machine involves a transformer for the power supply, welding electrodes, and other components that allow controlling the parameters in welding work (weld current, pressure, voltage, etc.). Spot welding machines are usually water-cooled because for a fraction of a second, very high heat is generated.
