3.2 + ” Marking on the welding current socket
The + sign indicates the positive pole of the welding power source. The earth cable is
connected to this socket when TIG welding.
3.3 “ Marking on the welding current socket
The - sign indicates the negative pole of the welding power source. The torch is
connected to this socket when TIG welding.
4 Mains power supply
The welding unit must be fitted with the correct mains supply plug which fully complies with
the International electrical standards and the local electrical regulations. The unit must only
be operated with fuses or circuit breakers with a maximum current rating of 16A. When the
mains power is switched on, the mains ON/OFF switch on the back of the unit is illuminates.
If the TIGER 170 is switched ON and OFF frequently (in quick succession), the unit may
automatically switch over to the power supply protection mode. In this mode, the unit cannot
be re-started and the green indicator lamp flashes. If this occurs, switch the unit OFF and
wait for approx. 2 minutes. The unit can then be restarted.
5 Installation
Care should be taken during installation of the unit to ensure that the ventilation slots are not
covered and the area where the machine is to be used affords a protection classification of
IP23.
6 Description of Welding processes
6.1 TIG Welding
6.1.1 Principle of the TIG welding process
The unit supplies a current up to 170 A DC for the TIGER 170 and 210 A for the TIGER 210
for TIG welding. The mains current limiting function is inactive during the TIG welding mode.
Despite the higher output current, the power drawn from the mains supply is lower than
required for stick electrode welding; the mains fuse is therefore unlikely to trip-out during TIG
welding.
During TIG welding, a welding arc is established between a tungsten electrode and the
workpiece. The shielding gas normally used is an inert gas such as pure Argon, Helium or a
mixture of both.
The negative pole of the power supply is connected to the tungsten electrode, the positive
pole is connected to the workpiece. The tungsten electrode is the conductor and the current
carrier (non-consumable electrode). The filler metal required is fed manually in the form of a
rod or by a separate cold wire feed unit. The tungsten electrode, and the welding pool is
protected from the atmosphere by the inert shielding gas supplied from the gas nozzle.
7
6.1.2 Arc ignition with INTIG Energy
The highly intelligent processor ensures that the ideal ignition energy is automatically chosen
depending upon the actual weld current setting, this applies not only for HF, but also for the
Lift-Arc ignition sequence.
When the selector switch is set to position ´"HF On", the high-frequency ignition unit is
ready for operation. To ignite the arc, the electrode must be held about 3 to 5 mm above the
workpiece. When the torch button is pressed, the shielding gas is pre-ionised by a high-
voltage, the current flows between the end of the electrode and the workpiece so that the
main arc is established. The ignition of the arc without contact between the tungsten
electrode prevents tungsten inclusion in the weld. once the arc has successfully been ignited
the high-frequency ignition unit is switched off automatically during welding.
When the selector switch is set to position "HF Off", contact ignition can also be carried
out using the processor control ignition system (Lift Arc) to strike the arc. In order to ignite the
welding arc, the tip of the electrode must be placed on the workpiece and the torch button
depressed. The processor control system reduces the ignition current so that the tip of the
electrode does not heat up. The electrode is then gradually lifted away from the workpiece,
this action ignites the arc under the system processor control, this results in arc ignition
without HF and also minimum wear on the tungsten electrode. This process is essential
when welding in areas where sensitive electronic equipment is in operation (e.g. repair welds
on CNC-controlled machines) and where there may be a risk of damage caused by high-
voltage.
When the selector switch is set to position "Electrode“, the HF ignition system is
automatically disabled.
The electrode diameter depends on the welding current. A diameter of 1.6 mm is
recommended for welding currents up to 70 A and 2.4 mm for higher currents.
6.1.3 The Non-latch torch button operation mode sequence
Step 1: Activate torch button
° The solenoid valve for the shielding gas is energised
° The arc ignition cycle starts after the fixed gas pre-flow time (0.1 sec.) has elapsed
° The set welding current is automatically reached after the up-slope time (0.1 sec)
has elapsed.
Step 2: Release torch button
° The current falls to 20% of the set welding current after the down-slope time has
elapsed, the arc is then automatically switched off.
° The shielding gas continues to flow for the duration of set gas post-flow time.
Non-latched welding mode is recommended for rapid, controlled tacking and manual spot
welding.
6.1.4 The Latched torch button operation mode sequence
Step 1: Activate the torch button
° The solenoid valve for the shielding gas is energised
° The arc ignition cycle starts after the fixed gas pre-flow time (0.1 sec.) has elapsed
° The welding current rises to 50% of the value set on the main current potentiometer
8
GB
Step 2: Release torch button
° The set welding current is automatically reached after the up-slope time (0.1 sec)
has elapsed.
Step 3: Activate the torch button once again
° The welding current falls to 20% of the welding current set on the main current
potentiometer for the duration of the downslope time
° The welding current remains at this 20% level.
Step 4: Release torch button
° The arc is extinguished
° The shielding gas continues to flow for the duration of the gas post-flow time.
In the latched torch button operation mode, the operator does not need to keep the torch
button pressed, allowing welding for a relatively long period of time without fatigue.
6.1.5 Gas post-flow timer (0.5 s 25.0 s)
The gas post-flow time is the time which elapses after the arc is extinguished and before
the shielding gas solenoid valve is de-energised. The shielding gas protects both the
workpiece and the tungsten electrode from contamination form the surrounding atmosphere
until they have cooled down sufficiently.
6.1.6 Downslope timer Crater fill (0.0 s 10.0 s)
The downslope timer is the time during which the welding current decays to the crater fill
current. In the Non-latched operation mode, the downslope time begins as soon as torch
button 1 is released. In the Latched operation mode, the downslope time commences when
torch button 1 is activated during welding. The longer the setting of the downslope time, the
lower the risk of creating end crater cracking.
6.1.7 Manual Pulsing function
If the torch button is activated during the downslope when in the non-latched TIG 2 mode,
the welding current immediately rises to the value set on the main current setting
potentiometer. The length of each pulse and is manually controlled by the operator
depending upon when he activates the torch button, as a result the average heat input will be
reduced.
6.2 Stick Electrode (MMA) welding
6.2.1 Stick Electrode welding in the Fuse Hold mode
In this mode of operation, the actual current drawn from the mains is continuously monitored.
If necessary, the welding current is reduced to the level required to prevent the mains fuse
form tripping out. A quick acting miniature circuit breaker similar to the type normally installed
in households should be installed in the mains supply cabinet as the Fuse Hold function is
designed for use in conjunction with this type of circuit breaker.
The machine is designed for use with all the common types of stick electrodes. The
maximum current is 140 A for the TIGER 170 and 160 A for the TIGER 210. If a higher
current is set, the current is automatically limited to 140 A / 160 A.
This current is usually sufficient to weld most common types of stick electrodes of up to
3.25mm diameter.
9
For the precise selection of the electrode polarity and current settings for individual
electrodes, please refer to the electrode manufacturer's instructions.
If for some reason there is a permanent short circuit between the electrode and the
workpiece, the Anti-Stick Function will automatically operate after approx. 1.3s, this then
limits the output current to approx. 35 A.
6.2.2 Stick Electrode welding with the BOOSTER Mode
In this mode of operation, the mains fuse monitoring function is automatically de-activated.
The maximum possible welding current is then 150 A for the TIGER 170 and 170 A for the
TIGER 210. If a higher current is selected, the welding current output is automatically limited
to 150 A /170 A.
6.2.3 Anti-Stick Function
If there is a permanent short circuit between the electrode and the workpiece during welding,
the Anti-Stick Function is automatically activated after approx. 1.3s. This function
automatically limits the welding current to approx. 35 A. This prevents the electrode from
overheating and burning out. The operator terminates the short circuit simply by removing
the contact between the electrode and the workpiece.
6.2.4 INTIG Energy for electrode welding
The INTIG energy (Intelligent Ignition Energy) automatically pre-sets a high power ignition
current sequence, which ensures reliable and smooth ignition when stick electrode welding.
Electrode sticking is prevented during re-ignition even with basic electrodes as the high
power ignition current pulse is only activated as the electrode is lifted off following contact
between the electrode and the workpiece, (similar to the Lift-Arc function for TIG welding).
7. Remote control units
7.1 TIG PLUS 1 foot-operated remote current control unit
(Article No. 753 1001)
The TIG PLUS 1 remote control unit is equipped with a foot-pedal for the infinitely varying the
output current during welding. When the pedal is fully depressed, the welding current
reaches the full value pre-set on the machine. The machine can therefore be set to the
maximum current required, allowing optimum resolution over the required operating current
range.
The TIG PLUS 1 remote control unit also incorporates a rocker switch which has the
following function:
- Hand control signal
The welding current is switched on and off using the torch button; the non-latch and latched
functions as well as the downslope time are active and can be selected on the machine. The
foot pedal controls the welding current, it is not de-activated! This type of operation is
intended for mass production applications where the welding current usually remains
constant and only needs to be reduced slightly from time to time. The current ramping
functions which are active in this mode of operation are therefore beneficial.
10
GB
- Foot control signal
In this mode of operation the welding current is switched on and off using the pedal and is
controlled by the operator using his foot. The welding machine automatically operates in the
non-latch mode only. The upslope and downslope times are automatically set to their
minimum values.
Warning: Ensure that accidental operation of the machine is prevented by accidentally
depressing the foot switch. When the foot pedal is activated, there is a danger of electric
shock caused by the high voltage pulses generated by the welding set!
7.2 TIG PLUS 2 hand-operated remote control unit (order no. 753 1002)
The TIG PLUS 2 hand-operated remote control unit allows the welding current to be adjusted
not only before but also during the welding operation. When the hand regulator is set to
100%, the welding current reaches the full value set on the welding output potentiometer on
the machine. The machine can therefore be set to the maximum current required, allowing
optimum resolution in the required current range. The welding current is switched on and off
using the torch button; the Non-latch and latched operating modes as well as the downslope
time are active and can be selected on the machine.
7.3 REHM SR17/4m torch with current control potentiometer and leather
outer cover (Article No. 763 1711)
The REHM R-SR17/4m TIG torch with current control potentiometer and leather outer cover
offers the same functionality as the hand-operated remote control unit described in Section
7.2 above. The welding current can be set and adjusted, prior to and during welding using
the adjustment potentiometer which is integrated within the torch handle. The torch is
connected to the standard torch control and remote control sockets of the TIGER 170/210.
The REHM R-SR17/4m TIG torch with current control potentiometer and leather outer cover
is specifically designed for use with the electronic control of the TIGER 170/210.
WARNING: The use of any other TIG torches with remote control functions except those
specifically supplied by REHM on the TIGER 170 will void the manufacturers warranty.
7.4 TIGER 170 SET (Article No. 150 3171)
TIGER 170 complete in a metal carrying case, together with the REHM R-SR 17/8m torch
with leather outer sleeve and integrated current setting potentiometer. Pressure regulator,
and Workpiece return cable 4m long. The carrying case is of a robust design and affords
protection for the welding machine and accessories. The case is fitted with high quality
catches which can be locked. The unit has very modest dimensions (Lx B x H: 565 x 360 x
200 mm) and weighs a mere 18 kg, making it the ideal companion for the arduous life in the
workshop as well as the building site.
8. Limitations of Application
The units can be used in any environmental conditions which afford protection corresponding
to Protection Classification IP23 or less. For welding in certain locations (e.g. stables), the
Protection Classification of the welding units has to meet special requirements. The use of
11
machines in such an environments should be carefully examined on a case by case basis.
The units are not designed for multi-shift operation.
9. Maintenance
The units do not require regular maintenance However the condition of the electrical cables
and plugs must be checked before using the machine.
9.1 Proper waste disposal
Only for EU countries.
Do not dispose of electric tools together with household waste material.
In observance of European Directive 2002/96/EC on waste electrical and
electronic equipment and its implementation in accordance with national
law, electric tools that have reached the end of their life must be collected
separately and returned to an environmentally compatible recycling facility.

La tension à vide est appliquée à la torche ou au porte-électrode.
Quand la lampe témoin clignote, la surveillance interne est déclenchée. Le
poste est remis en service en coupant puis rétablissant le courant au
commutateur principal. Merci d’en informer le Service Clientèle REHM (RKS).
Témoin de température. La diode luminescente (jaune) s’allume lorsque la
température maximale autorisée du poste est dépassée. Tant que cette diode
est allumée, le courant de sortie est coupé. Après refroidissement du poste, la
diode s’éteint et le soudage peut être repris automatiquement. Quand le témoin
clignote, la surveillance interne est déclenchée. Le poste est remis en service
en coupant puis rétablissant le courant au commutateur principal. Merci d’en
informer le Service Clientèle REHM (RKS).
3.2 Marquage « + » sur la douille de courant de soudage
Le signe « + » indique le pôle positif de la source de courant de soudage. Dans le soudage
TIG, le câble de mise à la masse est connecté à cette douille.

3.3 Marquage « - » / symbole TIG sur la douille de courant de soudage
Le signe « - » indique le pôle négatif de la source de courant de soudage. Dans le soudage
TIG, la torche est connectée à cette douille.
4 Branchement au secteur
Le poste de soudage est muni d’une fiche de prise de courant de sécurité. Le poste
fonctionne sous un courant nominal de 16 A avec des coupe-circuit ou des disjoncteurs de
protection de canalisations. Le mode de service EIN (MARCHE) est indiqué par l’allumage
du commutateur principal placé au dos.
Lors de fréquentes (brèves et successives) activations et désactivations du TIGER, il peut
arriver que le poste commute en mode protection, dans lequel il ne peut s’amorcer et la
lampe témoin de marche verte s’allume et s’éteint. Dans ce cas, mettre le poste hors service
et attendre 2 minutes environ. Le poste peut alors être remis en service.
5 Installation
Lors de l’installation des postes, veiller à ce que les grilles d’aération ne soient pas
recouvertes et à ce que l’environnement soit conforme à la classe de protection IP23.
6 Modes de soudage
6.1 Soudage TIG
6.1.1 Principe du procédé de soudage TIG
Pour le soudage TIG, le poste met à disposition un courant pouvant atteindre 170 A / 210 A.
Dans cette fonction, la limitation du courant du secteur n’est pas activée. Étant donné que,
malgré un courant plus important, la puissance utile en mode TIG est inférieure à celle du
soudage avec électrodes, il ne faut pas s’attendre ici à un déclenchement de coupe-circuit.
Dans le procédé de soudage TIG, l’arc électrique se forme librement entre une électrode en
tungstène et la pièce d’œuvre. Le gaz protecteur est un gaz rare tel que l’argon, l’hélium ou
un mélange de ces deux gaz.
Le pôle négatif de la source d’énergie est sur l’électrode en tungstène, le pôle positif sur la
pièce d’œuvre. L’électrode conduit le courant et porte l’arc électrique (électrode
permanente). Le métal d’apport est appliquée sous forme de baguette tenue à la main ou
sous forme de fil par un appareil d’alimentation en fil froid séparé. L’électrode en tungstène
et le bain de fusion ainsi que l’extrémité en fusion du métal d’apport sont protégés de l’entrée
de l’oxygène de l’air par le gaz inerte protecteur qui s’échappe des buses disposées de
manière concentrique autour de l’électrode.
6.1.2 L’amorçage de l’arc électrique avec INTIG-Energy
Avec le mode INTIG-Energy (Intelligent Ignition Energy), le TIGER 170 / 210 maîtrise la
forme intelligente de commande d’énergie d’amorçage. La commande à processeur règle de
