Mode Functional Description
CONTINUOUS (2T)
This mode of welding is used to weld two or more components together with
a continuous weld.
SPOT
This mode of welding is used to weld two plates together at a desired location
by melting the top & bottom plates together to form a nugget between them.
The spot time period is set by the SPOT TIME control shaft located in the
electrode wire compartment.
LATCH (4T)
This mode of welding is mainly used for long weld runs, as the operator need
only press the trigger to activate the weld, then press the trigger again to stop.
This obviates the need for the operator to depress the trigger for the complete
length of the weld run.
