A fastener and ceramic ferrule are firmly placed against the work surface under spring tension.
|
Upon triggering, the weld gun automatically lifts the fastener from the base metal and initiates a controlled electric arc which melts the end of the fatener and a portion of the base metal.
|
A ceramic arc shield concentrates the heat and retains the molten material in the weld area for maximum weld strength and reliability.
|
At the precise moment the fastener and the parent metal become molten, the fastener is automatically plunged into the work surface. The metal solidifies and a high quality fusion weld is completed.
