WeLDING
There are several different stud welding processes that this welder can perform. Be sure that your stud weld tool is
set up properly for the process you intend to use. See Section 5 for discussion of different processes.
Position the weld tool against the work. Press down on the stud weld tool to make sure the ferrule or spark shield sits firmly
against the work. While holding the weld tool in position, pull the trigger. The weld will initiate (gas flow will start if the gas
module is enabled) and complete. Continue to hold the weld tool against the work for 1/2 sec to allow the molten metal to
cool. Pull the weld tool off of the stud. This completes a weld sequence.

Accessing, using or understanding these features is not necessary for successful stud welding. These features increase
the functionality, convenience and ease of use of the stud welder.
AUTO WeLD
This feature simplifies set up for the less experienced operator and minimizes adjustments required for changes in
base/stud material and setup. This mode is called Auto Weld since it allows the operator to set up the power supply based
on the fastener size and type rather than requiring the operator to know correct time and current settings. NT stands for
No Thread, fT stands for Full Thread, PD stands for Pitch Diameter.
The lower control knob selects the stud material. Choices are: STEEL for low carbon steels (C1008-C1018), ALLOY for
stainless steels.
The operator then welds normally. The system measures parameters during the weld cycle and adjusts the weld to attempt
to achieve optimum weld results. The Auto Weld feature is not intended to solve all welding problems. It has been designed
to weld well in typical applications. It can compensate for variations in materials and variations in the stud weld tool lift
settings.

towards the floor. Welding in other positions will require the manual mode and adjustments to parameters. The auto
settings also assume that for studs 1/2" (12mm) and larger that the stud weld tool is using a plunge dampener.
If the Auto Weld mode is not providing satisfactory weld results, use the manual mode and set the weld parameters to achieve your
desired results.
This feature is activated by the
green LED in the Auto Weld button will light indicating the power supply is in
Auto Weld mode. If the screen is locked it can not be changed. See unlocking
screens later in this manual.
