INSTALLATION, OPERATION AND SETUP
Use the Multi Function Control (24) to adjust the Electrode size being used.
• Press the BACK button (22) or FORWARD button (23) until the Base Current A1 Led (44) 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 (50) will illuminate.
If the Electrode Diameter Out-of-Range indictor Led (50) is illuminated, it is still possible to weld.
Note that other parameters may need to be set, according to the operating mode selected, Please refer
to the tables below.

Table 3-3: Normal Welding Current for GTAW Electrode size
Note that Normal recommended Welding Current AC Amps are dependent on the type of electrode and on the
AC Balance Parameter setting.

Shielding Gas Pre-Flow time
This parameter operates in
GTAW modes only and is used
to provide gas to the weld zone
prior to striking the arc, once the
torch trigger switch has been
pressed. This control is used
to dramatically reduce weld
porosity at the start of a weld.
0.1-10.0 seconds
0.1
Start Current AS
This parameter operates in
GTAW modes only and is used
to set the start current for TIG.
In 4T mode the Initial Current
remains on until the torch trigger
switch is released after it has
been depressed. In 2T mode the
Initial Current remains on for the
Start Current Time tS and then
the Up Slope current ramp will
commence.
5 – 200% of Welding
Current A1
The maximum
welding current
in GTAW mode is
limited to 220 for
the Transtig 220AC/
DC and 300A for the
Transtig 300AC/DC
When A1=100A
50
Start Current Time tS
(2T normal mode only)
This parameter operates in 2T
GTAW modes only and set the
time the Start Current is active,
after which the Up Slope current
ramp will commence.
