its lowest value, the welding is soft, with the highest value rough, and the power
pulse is stronger when the arc voltage drops.
TIG welding
With Wameta MULTIMIG PRO 180 SYN you can weld with TIG DC. In TIG
welding, the metal of the workpiece is melted by an arc from a non-melting
tungsten electrode. The welding melt and electrode are protected by inert gas.
Designated filler material can be added to the process by hand or mechanized.
For TIG welding, Wameta TIG-Lift torch is required (article number 31WP.17V-
12-2).
Set the welding machine to OFF from the main switch on the back panel.
Connect the earth cable to the PLUS connector. Connect the TIG torch to the
MINUS connector. Connect the gas hose to the gas connection of the Argon
pressure reducer. Open the gas valve carefully. Open the gas tap on the handle
of the TIG torch. Adjust the gas flow meter to about 8 l / min. Close the gas tap
on the torch handle.
Set the machine on from the main switch on the back panel. Select the TIG LIFT
mode from the front panel selector.
Contact ignition. Warning! When the machine is started, the ignition potential of
the TIG electrode is generated. Do not touch the electrode when the machine is
running, the potential can be released and cause an unpleasant electric shock.
Open the gas tap on the torch handle.
To light up the TIG arc:
Touch the workpiece with the gas ceramic so that the
electrode is on the ignition point, but does not touch the
workpiece.
Tilt the torch so that the electrode touches the
workpiece.
Lift the electrode at a distance of 2-5mm from the
workpiece; the LIFT-ARC device lights up the arc.
The arc turns off when the burner is pulled out of the
workpiece. It is advisable to bring the torch to the end of
the weld immediately after turning off without touching
the workpiece so that the glowing metal will be protected
by the shielding gas. When the weld no longer glows,
the gas tap can be closed.
