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 d angerous 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.
Aristotig 160 S is a rectifier based on inverter technology and designed for TIG
welding and welding with coated electrodes.
This model is also known as LTR 160.
Inverter technology contributes to low energy consumption, low weight and compact
dimensions.
The advanced electronic design permits rapid regulation and first class welding char-
acteristics.
Aristotig 160 S is available in two versions, one with a central socket and one with
an OKC socket for connecting a TIG torch.
Aristotig 160 S is supplied complete with 5 metre mains cable, 5 metre return
cable,
1 cable connector, gas hose and hose clamps.
Versions with a central socket are also supplied with a protective cover to protect
connections from slag.
An optional handle b racket can be fitted to the machine for winding up cables and to
protect the control panel.
Two different trolleys are available to facilitate transport with a gas bottle.

4 INSTALLATION
WARNING
This product is intended for industrial use. In a domestic environment this prod-
uct may cause radio interference. It is the users 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 3x2.5 mm

*) When welding with max 100 A a 10 A slow rupture fuse is sufficient.
*)With 16 A slow fuse, max. 150 A, 20% duty cycle for MMA welding.
Aristotig 160 S are equipped with m ains voltage compensation, which means that a
¦10 % variation in the mains voltage only results in a ¦0,2%variationintheweld-
ing 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.

S Using the remote control socket on the machine the current can be remotely
regulated in TIG and MMA modes.
S Selector switch is used to select remote control operation.
S PHA5 remote control unit allows use of pulsed current in TIG mode.
When the main power switch is switched on the white indicating lamp, on the front,
comes on.
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. The 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 automati-
cally 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 cur-
rent during striking.
Mode 2/4--stroke
2 stro ke: arc is struck when the torch trigger is depressed and extinguished when
the trigger is released.
4 stro ke: there is no need to keep the torch trigger depressed during the welding se-
quence. Press and release the trigger to strike the arc. Press and release the trigger
again to extinguish the arc.
5.1 LIFTARC
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 ac-
cordance with the preset slope--down time.

6 MAINTENANCE
Generally, Aristotig 160 S do not
require any maintenance. Normally,
it is sufficient to blow out the ma-
chine 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. .
