ASSEMBLING a gas-cooled TIG torch
Pull back the rubber sleeve from the rear of the torch
Screw the hexagon nut (width across = 21) of the gas+current
connection onto the torch connector point on the machine
and tighten firmly.
Push the rubber sleeve back over the hexagon nut.
Plug the control plug into socket

REMOTE CONTROL OPERATION
Remote control units are intended for use in situations where the
welding parameters must be set directly from the welding work-
place. The remote control unit is connected electrically to the
power source by means of special cables 5 or 10 m in length
(voir déscription des éléments de commande page 69, point
The following types of remote control unit are available:
1. Manual electrode and TIG remote control unit
2. Manual electrode and TIG remote control unit
3. TIG pulsed-arc remote control unit
4. TIG spot-welding remote control unit
5. TIG remote-control pedal unit
TELEREGULATEUR DE SOUDAGE MANUEL
A ELECTRODE ENROBEE TIG TP3
(seulement pour TT 330)
Cette commande à distance du poste de travail est utilisée
spécialement pour le soudage manuel à l'électrode enrobée et le
soudage TIG C.C. (aimant de fixation de la commande à distance
sur la pièce à travailler est monté)

ARC FORCE CONTROL DIAL
Influences the short circuit amperage at the moment of drop
transfer (from electrode to workpiece)
At scale setting "0" TIG there is no increase at all in the short
circuit amperage at the moment of drop transfer
(Constant current characteristic = soft arc; Fig. 27a)
Range of application:
TIG-DC welding
Welding using rutile electrodes (fine globules)
Basic sheathed electrodes in the medium and upper amperage
ranges
Caution! When welded at low load, basic-sheathed electrodes
tend to "GET STUCK" on the workpiece.
At scale setting "10"
crease in amperage at the moment of drop transfer
(Constant current characteristic with electronic arc-force effect;
5 = hard arc; Fig. 27a)
Range of application:
Basic sheathed electrodes (coarse-globule), when these are
to be welded in the lower amperage range
(vertical-up seams, edge hardfacing welds, root welding etc.)
there is a very considerable in-
