2SAFETY
WARNING
ARC WELDING AND CUTTING CAN BE INJURIOUS TO YOURSELF AND OTHERS. TAKE PRECAUTIONS WHEN WELDING. ASK FOR YOUR EMPLOYER’S SAFETY PRACTICES WHICH SHOULD BE
BASED ON MANUFACTURERS’ HAZARD DATA.
ELECTRIC SHOCK -- Can kill
S Install and earth the welding unit in accordance with applicable standards.
S Do not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing.
S Insulate yourself from earth and the workpiece.
S Ensure your working stance is safe.
FUMES AND GASES -- Can be dangerous to health
S Keep your head out of the fumes.
S Use ventilation, extraction at the arc, or both, to keep fumes and gases from your breathing zone and
the general area.
ARC RAYS -- Can injure eyes and burn skin.
S Protect your eyes and body. Use the correct welding screen and filter lens and wear protective
clothing.
S Protect bystanders with suitable screens or curtains.
FIRE HAZARD
S Sparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby.
NOISE -- Excessive noise can damage hearing
S Protect your ears. Use ear defenders or other hearing protection.
S Warn bystanders of the risk.
MALFUNCTION -- Call for expert assistance in the event of malfunction.
READ AND UNDERSTAND THE INSTRUCTION MANUAL BEFORE INSTALLING OR OPERATING.

3.2 Equipment
Caddy Tig is supplied with:
S Mains cable ( 3 metres)
S Return cable with earth clamp (2.5 metres)
3.3 Field of application
Tig--welding
TIG welding is particularly useful when high quality standards are required and when
welding thin sheet.
Before using the Caddy for TIG welding it must be equipped with a TIG torch
(HW 20 ARVSW--3,8m), and gas valve, a cylinder of argon, an argon regulator,
tungsten electrodes and, if necessary, suitable filler metal.
The best method to use is the touch start, where you gently stroke the tungsten
electrode against the workpiece to establish the arc.
Caddy Tig 150 both supply direct current, which allows you to weld most alloyed and
non--alloyed steels, stainless steels and cast iron.
Caddy Tig lets you weld with coated electrodes from 1.6 mm to 3.25 mm diameter.
4 INSTALLATION
WARNING
This product is intended for repair and maintenance welding
In domestic or office environment this product m ay cause radio interference.
It is the responsibility of the user to take adequate precautions.
4.1 Placing
Place the machine so that there is nothing to prevent the cooling air from passing
through it.
4.2 Connection
4.2.1 Mains connection
The rating plate including connection data is placed on the underside of the welding
power source.
Connect the welding power source to an earthed mains terminal.
Make sure the welding power source is connected for the correct mains voltage and
properly fused.
S Mains voltage 230 V
S Mains frequency 50--60 Hz
S Fuse, slow rupture 16 A
S Mains cable, area 3 x 1,5 mm

4.2.2 Connection of welding and return cable
TIG
For TIG welding, the torch is connected to the negative
terminal and the control cable is connected to the Canon
socket on the front panel. Connect the return
cable to the positive terminal, and the gas hose
to the regulator on the gas bottle.
Return cable
Attach the r eturn cable clamp to the
workpiece and make sure there is good
contact between the workpiece and the
socket for the return cable on the
power source.
MMA
The welding power source has two terminals, one plus and one minus pole, for the
connection of the welding and the return cable. Connect the welding cable to the
pole indicated on the package of the electrode to be used.
5OPERATION
5.1 Start--up
TIG
S Connect the TIG torch and return cable.
S Connect the shielding gas to the torch.
S Set the toggle switch on the front of the power source to the TIG setting.
S Switch on the power source by setting the power switch to setting 1.
S Set the welding current using the knob on the front of the power source. Use the
recommended welding current range shown on the electrode packaging.
S Strike the arc without pressing the trigger, then press the trigger and allow the
current to rise to the preset value.The RK function allows you to control the heat
input by pressing or releasing the trigger.
MMA
S Make sure that the cables and the earth clamp are properly connected.
S Start the welding power source by setting the mains switch to position 1.
S Set the welding current, using the knob on the front panel of the power source.
Follow the instructions on the electrode package for the recommended welding
current.
-- 3 5 --bt21e
5.2 Overload protection
Caddy Tig 150 are provided with a thermal cut--out to prevent overheating of the
welding power source. In the event of overload the supply voltage is interrupted and
the orange lamp on the front goes on. Resetting takes place automatically as soon
as the welding power source has cooled down.
5.3 Mains voltage compensation
Caddy Tig 150 both have mains voltage compensation, which means that + 10%
fluctuation in the supply voltage produces only + 0.2% variation in the welding
voltage.

6 MAINTENANCE
Note:
All warranty undertakings given by the supplier cease to apply if the customer
attempts to rectify any faults on the machine during the warranty period.
6.1 Cleaning
Normally it is sufficient to blow the welding power source clean regularly using dry
compressed air (reduced pressure), and to clean the filter in the front regularly.
In dusty and dirty environment the welding power source should be cleaned at
shorter intervals.
