Welding GTAW / GTAW-PULSE Process
Arc ignition can be achieved only by lift TIG method
(contact ignition and lift ignition).
Table 12. The Welding Programs

GTAW 3
GTAW-PULSE 8
Note: Before using the 8 program, the program had to
be assigned to the user memory.
Note: The list of available programs depends on the
power source.
Procedure of begin welding of GTAW/GTAW-PULSE
process:

Connect Lincoln Electric power sources using
ArcLink
®
protocol to communication to wire feeder.

Connect GTAW torch to Euro Socket [1].
Note: To connect GTAW torch, adapter TIG-EURO
has to be purchased (See "Accessories" chapter).

Connect the work lead to output sockets of the power
source and lock it.

Connect the work lead to the welding piece with the
work clamp.

Install the proper tungsten electrode in the GTAW
torch.

Turn the input power ON and wait until the PF22 will
not be ready to work with the power source - Status
LED [20] stops blinking and lights steady green light.

Set the GTAW or GTAW-PULSE welding program.
Note: The list of available programs depends on the
power source.

Set the welding parameters.

The welding machine is now ready to weld.
Note: Arc Ignition is achieved by touching the work
piece with the electrode and lifting it by a few
millimeters
– contact ignition and lift ignition.

By applying the principle of occupational health and
safety at welding, welding can be begun.
For 3 program can set:

Welding current [32]

Switch on / switch off the output voltage on the
output lead [24]
Note: It does not work in the 4-Step.

Postflow Time

2-Step / 4-Step

Crater [27]

Wave Control [27]:

HOT START
For 8 program can set:

Welding current [32]

Switch on / switch off the output voltage on the
output lead [24]
Note: It does not work in the 4-Step.

Postflow Time

2-Step / 4-Step

Crater [27]

Wave Control [27]:

Frequency

Background current

HOT START
HOT START
– value in percentage of nominal value
welding current during arc start current. The control is
used to set the level of the increased current and arc
start current is made easy.

Adjust range: from 0 to +10.
Frequency influences the width of the arc and the
amount of heat input to the weld. If the frequency is
higher:

Improves penetration and the microstructure of the
weld.

The arc is narrower, more stable.

Reduces the amount of heat input to the weld.

Reduces distortions.

Increases welding speed.

Note: Adjust range depend on the power source.
Background Current - value in percentage of nominal
value welding current. Adjusts the overall heat input into
the weld. Changing the background current changes
the shape of the back bead.

Note: Adjust range depend on the power source.
