6. TIG (WIG) welding
Although the welding units of the MobiARC series primary to be destined for the manual
electrode welding operation, you can use it nevertheless for TIG welding.
Therefore you need a TIG hose package with integrated gas valve. The ignition happens as
contact ignition with minimal current, whereby the damages on the needlepoint will be avoided
as for as possible. The following settings for TIG welding are other than the given values from
the manual electrode welding operation.
Establish the readiness for operation
•
Connect the hose package and the earth cable.
Plug the TIG hose package in the with „–“ marked socket,
plug the earth cable in the with „+“ marked socket. Lock the
bayonet lock.
Fixate the pole terminal of the ground cable at the workpiece. The
contact point must be cleared of paintworks, layers of fat and
oxide layers.
•
Pressure reducer have to be plugged on the protective gas cylinder
(Argon 4.6), gas hose of the hose package have to be plugged on
the pressure reducer, gas cylinder valve have to be opened and the
needed protective gas value have to be adjusted.
Adjust the welding current
•
Lay the electrode holder down on an insulated surface and carry
the step switch
1
in position .
Attention: Welding voltage is applied to the sockets!
•
Adjust the welding current I1 with the rotary knob
4
. You can
open the gas valve at their hose package.
The unit is now ready to weld.
5.2 TIG welding with remote controller
You have two options to use a remote controller. You can either use the manual remote
controller (art.-nr.
013.0.1059) or use the base remote controller for the energy regulation
(art-nr. 019.0.3000).
The remote controller will be plugged at the appropriate 10 pole socket on
the front. Please note that the remote controller must be activated.
