5.4 Connecting the shielding gas supply
Fasten the suitable flow regulator to the shielding gas canister with the corresponding tool. In doing so,
always observe the enclosed special operating instructions provided. We recommend argon with min. 99.99 %
purity, e.g. "Argon 4.6". With the help of the quick couplings, screw the pressure hose to the flow regulator and
the shielding gas connector (7) on the rear of the device until hand-tight.
Check regularly that all of the hose connections and the gas hose are in optimal
condition, are properly fastened and are airtight!
5.5 Inserting/changing the electrode
Please always check that the device is switched off, prior to exchanging the electrode.
This prevents uncontrolled triggering of the welding process. Caution: the electrode
issharp, risk of injury!
Lightly rotate the nozzle (2) and in doing so, pull it off of the hand piece (4). The nozzle is in place but
notscrewed on. Undo the union nut (3), remove the electrode (1) and insert the freshly abraded electrode
withthefreshly sharpened side facing outwards, tighten the union nut once more until hand-tight.
The correct electrode length can be easily set with the help
ofthemeasuring aid milled into the hand piece arm. Suitable
forright and left-handed users.
Now place the nozzle back on the hand piece. The electrode should
now protrude approx. 4-6 mm over the nozzle end.
Only use thorium oxide free original electrodes.
Subsequently insert the connector plug of the hand piece straight into the connection socket for the hand piece
on the front of the welding device housing and fasten in place by tightening the union nut hand-tight
inaclockwise direction. Insert the plug of the connecting cable used (such as a crocodile clip) into
theconnection socket for contact elements on the front side of the housing.
