Most commonly, the lightning current ceases in about a millisecond for a given stroke, but sometimes there is a continuing current on the order of 100 amps following one or more of the strokes. This is called hot lightning and it is the cause of lightning fires according to Uman.
For example, to MIG-weld 18-gauge steel in a single pass takes roughly 70 amps. Welding 1/4-inch steel in a single pass requires roughly 180 amps. The phrase in a single pass is the key. Because a series of thin passes can be made to weld thicker material per pass, less amperage is required. However, multiple passes take more time.
