2SAFETY
WARNING
READ AND UNDERSTAND THE INSTRUCTION MANUAL BEFORE INSTALLING OR OPERATING.
ARC WELDING AND CUTTING CAN BE INJURIOUS TO YOURSELF AND OTHERS. TAKE PRECAU -
TIONS 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.
PROTECT YOURSELF AND OTHERS!

3 INTRODUCTION
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.
Handy Tig 150 is a welding rectifier that is based on inverter technology and
intended for TIG welding and welding with coated electrodes.
Inverter technology contributes to low energy consumption, low weight and compact
dimensions.
The advanced electronic design permits rapid regulation and first class welding
characteristics.
Handy Tig 150 is supplied complete with 3 m etre mains cable, 3 metre return cable,
1 cable connector, gas hose and hose clamps.

4 INSTALLATION
WARNING
This product is intended for industrial use. In a domestic environment this
product may cause radio interference. It is the user’s responsibility to take
adequate precautions.
Mains voltage 230 V ¦ 10 %, 1--phase
Mains frequency 50--60 Hz
Fuse, slow rupture 16 A*)
Mains cable, cross section 3x1.5 mm
2
Welding cable, cross section 25 mm

*) When welding with max 100 A a 10 A slow rupture fuse is sufficient.
*)With 16 A slow fuse, max. 150 A, 25% duty cycle for MMA welding.
Handy Tig 150 are equipped with mains voltage compensation, which means that a
¦10 % variation in the mains voltage only results in a ¦0,2%variationinthe
welding current.
To reduce the voltage drop when using a long cable it can be advisable to select a
heavier cable cross section.
1. Place the equipment in a suitable place and make sure the rectifier is not cov-
ered or set--up so that cooling is prevented.
2. Make sure the machine is connected to the correct mains voltage.
Earthaccordingtoapplicabledirectives.
3. Connect the shielding gas.
4. Connect the TIG torch and the return cable or the MMA welding cables.
The machine is now ready for welding.

4 Lift--Arc/HF unit /MMA 10 Connection for return cable when TIG
welding/connection for electrode
5 Current setting 11 Dust filter
6 Trigger switch, TIG torch
For MMA welding, the electrode cable is connected to socket 10 and the r eturn cable
to socket 9.
For TIG welding, the TIG torch is connected to socket 9 and the return cable to
socket 10.
To take your mind off the risk of overloading the machine it has been equipped with
an integrated thermostat that trips if the temperature becomes too high.
When this occurs the welding current is cut out and the yellow indicating lamp comes
on. When the temperature has dropped the thermostat automatically resets.

Mode = HF
When the torch trigger is pressed the gas starts flowing. T he high frequency unit is
switched on and produces a spark between the electrode and the work piece, which
ionises the gas and ignites the arc. Once the arc is stable the HF unit is
automatically switched off.
Mode = MMA.
In this mode the machine is set up for welding with coated electrodes. The HF unit
and Lift--Arc are disabled and the Hot--start unit is now activated to give a higher
current during striking.
Mode
= Lift--Arc.
The torch electrode is positioned at the point where you want to start welding, when
you press the trigger and raise the torch the arc is struck.
Using the built--in slope--up function the current rises to the preset value. When you
want to stop welding you release the switch and the current slowly decreases in
accordance with the preset slope--down time.

6 MAINTENANCE
Generally, Handy Tig 150 do not require
any maintenance. Normally, it is
sufficient to blow out the machine using
clean, compressed air annually, and the
dust filter should be cleaned regularly.
If the machine is set up in dusty or dirty
environments the machine and dust
filter should be cleaned more often.
