Operation Principle: AC motors work on the principle of electromagnetic induction, generating torque through rotating magnetic fields. DC motors rely on magnetic fields created by direct current flowing through windings, allowing for instantaneous control of speed and torque.
[pdf] One of the main advantages is their ability to deliver consistent and precise welds. The fixed position ensures welds are applied exactly where needed, leading to higher quality and uniform results. Spot welding is a quick process that doesn’t require filler materials.
