Q. What do you mean by Weld and hold time?

Weld time

During this period the welding current flows through the circuit, i.e., it enters from one electrode, passes through the work pieces and goes out from the second electrode.

Hold time

It is the time during which force acts at the point of welding after the last impulse of welding current ceases. The electrode pressure is maintained until the metal has somewhat cooled.
