Getting Ready To Weld - Pro Spot AL-5 Instruction Manual

AL-5
To Weld:
Insert a threaded stud into the matching electrode holder.
Place the gun in a perpendicular 90° position to the weld area.
NO GAP
In normal operation, the indicator light
on the front panel should be as
follows:
GRD
OV
READY
OH ON
When the stud is placed on the panel, the GRD (ground) Light should turn on and indicate that the
ground circuit is complete. If the voltage setting is changed, the ready light will go out until the
correct capacitor voltage has been verified. Once the correct capacitor voltage has been verified,
the light will turn on again.
The point on the stud creates an arc and the pressure on the stud collapses the point and melts
the base of the stud to the panel. All of this occurs in milliseconds to create a proper weld, if the
time were longer it could damage or blow a hole in the panel.
