DC TIG Screen Setup, Functions and Parameters
2. Stitch Timer: For Spot 0-5S; For Fast-Tack 0-25ms. The Stitch timer
duration is the “Arc Off” time. This is designed to cycle the arc off for
a specied period of time and to provide a repeating pattern of ON/
OFF cycles. The idea of the stitch parameter is designed to help cre-
ate an intermittent seam, with regularly-spaced welds. Used in in
conjunction with the Spot timer, the length or size of the weld can be
controlled. If single spot welds are desired for each trigger cycle, with
no repeating of the Arc, set “STITCH” to 0.0 Seconds. When used in
conjunction with the Fast-Tack Timer a series of rapid, successive
welds are made to create a ne bead on thin gauge material without
burning through or overheating the metal.
Special DC Spot Weld/ Fast Tack Functions and Settings.
1. Remote. Function is unavailable for status selection and adjustment.
However, it is xed to 2T mode. This requires the use of the mounted
torch switch when Spot Welding.
2. TIG Start. This function is unavailable for selection and adjustment
when either Spot or Fast-Tack are selected. However, it is xed to HF
mode. This is because the arc must start rapidly and cleanly when
Spot Welding.
3. Pulse. This function is unavailable for status selection and adjust-
ment when either Spot or Fast-Tack are selected. The function is
switched off due to the fact that pulse conflicts with the Spot Welding
Concept. Even if it were able to be used with Spot, in theory, incor-
rect frequencies of the Pulse rate could interfere with proper opera-
tion of the Spot function itself due to short cycle times.
4. Spot. The function can be set to Off, Spot, or Fast-Tack. Selecting
Spot or Fast Tack results in a signicant change of the graph line and
parameters and functions available for adjustment. The graph line is
the same in appearance between Spot and Fast-Tack.
