Holding the Stud Welder rmly with both hands and using a well-balanced
stance, rmly push the Stud (32) against
the metal surface until the Electrode
Assembly (26) is ush with the metal
surface. See FIGURE 3.
With the Electrode Assembly (26)
PERFECTLY SQUARE to the surface,
hold the Stud Welder very steady and
squeeze the Trigger (17) for only 1/2 to
1 second. Immediately release the Trig-
ger (17) after 1/2 to 1 seconds.
Note: It is normal for approximately 1/4” of
discoloration to show around the weld. If you hold the trigger down more than 1
second, the metal skin of the vehicle will burn.
Note: If the Stud Welder remains on too long (Approximately 6 seconds) the circuit
breaker will shut the unit down to protect it. To reset the Breaker, allow the unit to
cool down and then push the Circuit Breaker Reset (20).
Pull the Stud Welder directly back, leaving the Stud (32) in place. You will notice
the tip of the stud remains exposed.
When done with the Stud Welder, unplug the tool and store it safely.
