ATTENTION!
Use a gated welding torch with a 13mm bayonet
connector. Select the maximum current of the welding torch according to
the specifications.
If required, perform the additional functions specified for the argon arc welding process (see Section
6.1).
4.1.2. OPERATIONAL CYCLE OF THE ARGON ARC WELDING PROCESS
WITH TIG-LIFT FUNCTION
The procedure for changing the values of the operational parameters of the welding unit is described in
Section 6.1.
4.1.3. TIG-LIFT CONTACT ARC STARTING FUNCTION
This function of the control button on the welding torch is set by default and is designed for welding
torches with contact arc starting, without using oscillators and other like devices. In contrast to
conventional methods of arc starting, the contact arc starting prevents the formation of current surge
at the instant of time of the arc starting. As a result, disintegration of the no consumable tungsten
electrode and ingress of the electrode particles into the weld can be prevented.
ATTENTION
!
Open the valve of the welding torch before welding and
close it after the welding.
When this function has been activated, contact the electrode with the workpiece. It is allowed to
hold the electrode in this position for an unlimited length of time. When the operator is ready to
welding (for example, when the operator has lowered the protective shield and purged the weld area
with gas), it is necessary to lift the electrode tip slowly from the workpiece. The welding unit will
sense this action as a signal to start welding, and the welding current will be linearly increased to
the set value. To prevent surface melting of the electrode tip, the rate of lifting the electrode should
correspond to the set welding current value. The period
[TIME UP ARC]
of linear current rise is
discussed in
Section 4.6.
