3 INTRODUCTION
Caddy TIG HF is a welding power source based on the inverter technique, intended for
welding with coated electrodes (MMA welding) and with infusible tungsten electrode in
inert gas (TIG welding).
Caddy TIG HF is especially designed for high quality TIG welding due to a specific device
that allows the striking of the arc without touching the metal surface with the electrode.

Selecting the MMA welding with the selection switch and the led indication on the front
panel, coated electrodes from Ø1.6 mm to Ø 3.25 mm and also many Ø 4,00 mm can
be welded.
TTIIGG--wweellddiinngg
TIG welding is particularly useful when high quality standards are required and when
welding thin sheet.
Before using the Caddy TIG HF for TIG welding, it must be equipped with a TIG torch
with trigger switch, a cylinder of argon, an argon regulator, tungsten electrodes and, if
necessary, suitable filler metal.
Selecting the TIG process, in order to strike the arc, you only need to put the tip of the
tungsten electrode near the workpiece and to press the trigger switch; an high frequency
(HF) discharge will strike the arc.
When the TIG LIFT START welding process has been selected the arc ignition is obte-
ned touching the workpiece with the tip of the tungsten electrode, pressing the trigger
switch and lifting the electrode gently to estabilish the arc. In this way the short circuit
current is maintained to a minimum level, in order to prevent the wear of the tungsten
electrode, and to reduce contamination of tungsten in the weld pool.

The welding power source has two power terminals, one plus and one minus pole, for the
connection of the welding and the return cable. Connect the welding cable to the pole indi-
cated on the package of the electrode to be used.
Connect the return cable to the other terminal. Fit the earth clamp of the return cable to
the work-piece and make sure there is good contact between the work-piece and the
return cable terminal on the welding power source.

•Make sure that the mains cable is properly connected.
•Make sure that the welding cable or the connectors of the TIG torch and the earth
clamp are properly connected.
•Start the welding power source by setting the mains switch to position 1.
•Select the welding process you want pressing on the process selection switch.
Electrode welding process
TIG LIFT START process
TIG HF START process.
Light on the corresponding led confirm the choise.
•Set the welding current, using the knob on the front panel of the power source and
reading the current on the display.
Follow the instructions on the electrode package for the recommended welding
current in MMA welding.
In TIG welding the current must be appropriate to the workpiece and the welding
requirements.
For reducing the final crater in the weld pool is possible to select the ramp-down
function with the selection switch on the right of the front panel and to change its
value with the knob. After some seconds the control return to the welding current.
5 OPERATION

GB
55..22OOvveerrllooaadd pprrootteeccttiioonn
Caddy TIG HF is provided with a thermal cut-out to prevent overheating of the welding
power source. In the event of overload the supply voltage is interrupted, the yellow led on
the front goes on and an error code starts blinking on the display accordingly to the follow:
E01 = overtemperature
E03 = overload with respect to allowed duty cycle
In case of error E01 or E03 resetting takes place automatically as soon as the welding
power source has cooled down.
Error code E20 could also be displayed; in that case switch off and on again the machi-
ne: if E20 is still displayed, call Service.
55..33MMaaiinnss vvoollttaaggee ccoommppeennssaattiioonn
Caddy TIG HF both has mains voltage compensation, which means that + 15% fluc-
tuation in the supply voltage produces a negligible variation in the welding voltage.

In order to reduce noise, no load consumption and metallic powder movement, Caddy
TIG HF has a special device that control the fan velocity; the higher is the internal tem-
perature the faster is the fun speed.
