STUD WELD TOOL SETTINGS
Standard Draw Arc Weld Tool
The time & current setting in the previous section will vary with the stud weld tool's lift and plunge settings. Typical values
are 3/32" for weld tool lift and 1/8" for weld tool plunge. For this power supply, stud lift is recommended to be at 3/32".
QuikLinx Weld Tool
For QuikLinx tool set up, please see the QuikLinx Manual that came with the QuikLinx tool.
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 4 for discussion of different welding 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, press the trigger. The weld will initiate (gas flow will start if the gas
mode 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.

ADVANCED FEATURES

GAS MODE
The stud welding power supply supports gas arc welding. This mode requires a special stud weld gun that is equipped with the
proper accessories for gas arc stud welding. There are 3 different gas modes and each is indicated differently by the gas mode
indicator light:
Note: On power up, if gas mode is on, the unit will purge the gas lines for 5 seconds.

HAMMER MODE
This mode is most useful when welding on dirty, rusty, mill scale or painted surfaces (painted surfaces require a special stud).
The system automatically detects ground. If ground is not found the weld tool lifts and plunges to break through the scale or
paint. It will repeat this lift/plunge (hammer) sequence until ground is detected at which point the stud will weld. After the
set number of hammers, if the weld has not occurred, the system stops and returns to the ready state.
Shielding Gas is not being used
The gas pre-flows for .5 seconds. The weld completes and the gas post flows for .5 seconds.
The gas then shuts off. This sequence is followed for each weld.
For the first weld the gas pre-flows for .5 seconds. The weld completes and the gas continues
ON to flow. On subsequent welds there is no pre-flow, the weld begins immediately. The gas shuts
off after 20 seconds of inactivity.
