Figure 3-9: GTAW Spot Welding Mode with DWELL Time
To enable Spot Welding with Dwell Time (Stitch welding) the parameter “PSP” needs to be set to ON (refer secondary parameters) it is
possible to have automated spot welds with this Stitch function.
In 2T mode, the stitch welds are repeated for as long as the trigger is held in.
In 4T mode, press and release the trigger to start the stitch welds, press and release the trigger to end the stitch welds
The parameters tSP and tSO determine the spot time length and the dwell (off) time length
• Press the WELDING MODE (10) button to select GTAW SPOT mode. SPOT mode. The SPOT LED (13) will illuminate.
• Press the WELDING TYPE (17) button to select the welding output type
• Press the BACK button (22) or FORWARD button (23) so the Electrode Diameter LED (41) and inch LED (29) are illuminated.
Use the Multi Function Control (24) to adjust the Electrode size being used.
• Press and hold the WELDING MODE (10) button then press the SAVE (53) button.
• Press the BACK button (22) or FORWARD button (23) to select the “PSP” Parameter.
• Use the Multi Function Control (24) to set “PSP” to ON (to enable stitch welding
• Press the BACK button (22) or FORWARD button (23) until the Peak Current LED (43) is illuminated.
Use the Multi Function Control (24) to adjust the Welding Current for the Electrode size being used. If the Welding Current does not
match the normal operating range of the electrode the Electrode Diameter Out-of-Range indictor LED (49) will illuminate.
• Press the BACK button (22) or FORWARD button (23) until the left display shows “tSP”.
• Use the Multi Function Control (24) to set the required SPOT “ON” time required.
• Press the BACK button (22) or FORWARD button (23) until the left display shows “tSO”.
• Use the Multi Function Control (24) to set the required SPOT “DWELL or OFF” time required.
If the Electrode Diameter Out-of-Range indictor LED (49) is illuminated, it is still possible to weld.
