Figure 3-8: TIG Programming Mode
• Press the WELDING MODE (10) button to select the appropriate GTAW mode.
Several GTAW operating modes are available.
2T (normal mode). The 2T LED (16) will illuminate.
4T (latch mode). The 4T LED (15) will illuminate.
Tiptronic. The TIPTRONIC LED (14) will illuminate
SPOT mode. The SPOT LED (13) will illuminate.
2T PULSE (normal mode). The 2T LED (16) and PULSE LED (12) will illuminate.
4T PULSE (latch mode). The 4T LED (15) and PULSE LED (12) will illuminate.
• Press the WELDING TYPE (17) button to select the welding output type
Several GTAW operating modes are available.
AC welding output mode. The AC LED (21) will illuminate.
DC Negative welding output mode. The DC Negative LED (19) will illuminate.
HF AC welding output mode. The HF LED (18) and the AC LED (21) will illuminate.
HF DC Negative welding output mode. The HF LED (18) and the DC Negative LED (19) will illuminate.
!
WARNING
In HF operating mode, high voltage pulses are generated within the power source, to provide contactless
initiation of the GTAW welding arc. If HF operating mode is selected, high voltage will be present on the
tungsten electrode when the trigger is pressed. Never touch the tungsten welding electrode of any parts in
the welding circuit when the trigger is pressed..
• Press the BACK button (22) or FORWARD button (23) so the Electrode Diameter LED (41) and Inches LED (29) are illuminated.
Use the Multi Function Control (24) to adjust the Electrode size being used.
• 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.
If the Electrode Diameter Out-of-Range indictor LED (49) is illuminated, it is still possible to weld.
