5-19. Spot Time Control

1

Sequence Selection Switch −
Spot Position

Used with the (GTAW) TIG Spot
process, generally with a direct cur-
rent electrode negative (DCEN) set-
up.

2

Start Time/Spot Time Control

Use control to select 0−15 seconds
of spot time.

Use Amperage Adjust control (see
Section 5-8) to set amperage.

Application:

TIG spot welding is used for joining
thinner materials that are in close
contact, with the fusion method. A
good example would be joining coil
ends.

Current Control

2

Output (Contactor) Control

To read timer/cycle counter, hold
Current and Output (contactor) but-
tons while turning on power.

3

Timer Display

The hours and minutes are dis-
played on the volt and amp meters
for the first five seconds, and are
read as 1, 234 hours and 56 min-
utes.

4

Cycle Display

The cycles are displayed on the volt
and amp meters for the next five
seconds, and are read as 123, 456
cycles.
