Description of function Current I1 Current I2 Pulse time I1 Pulse time I2 Time Fig 3.3: Welding current during pulsed welding If a twin-button torch is used, pulsing can be switched off and also back on during welding by pressing torch button 2. If torch button 2 is pressed while the welding current is pulsing, pulsing is switched off and welding is continued using welding current I2.
The dual current switching can only be done in the latched torch trigger mode (4- step) without pulsing. The welding current I1 can be set within the following range: Tiger 170 DC and. AC/DC Tiger 210 DC and AC/DC 3 A … 170 A 3 A …...
Description of function before starting the welding operation. Whilst holding the button 2 down the value for the current will be shown on the digital display and using the turn and set knob the value can be adjusted as required. The Pulsed Function (Pulse time t2 –...
The setting for direct current is performed as described in section 3.1. The Tiger 170 AC/DC and Tiger 210 AC/DC can weld with either direct current (DC) or alternating current (AC). The Tiger 170 DC und Tiger 210 DC can only be use for direct current (DC).
Another special feature of the Tiger AC/DC machines is that in the AC welding mode the patented Rehm Automatic Frequency Control can also be selected. To active this function the selection “Aut” is made, this is the one before the 50Hz setting in the frequency function parameter.
Description of function Torch trigger 1 Solenoid valve Welding current Fig. 3.5 The current cycle diagram for latched trigger operation (4 step) Special Note: to Step 2 If the torch button is pressed during the downslope phase, the arc will extinguish and the shielding gas flows for the time set by the post flow gas parameter.
Description of function Torch trigger 1 Solenoid valve Welding current Fig. 3.6 The current cycle diagram for non-latched trigger operation (2 step). Special note: to step 2 If the torch trigger is depressed during the downslope then the welding current jumps back up to the I1 value. This torch operation enables manual pulsing to be achieved.
Description of function 3.3.15 Stick-electrode welding with the Booster-Function The setting for Booster function is performed as described in section 3.1. In the Booster mode the mains current monitoring function is deactivated, and the machine always welds with the welding current set (I1), which is on the TIGER 170 150 A and the TIGER 210 170 A.
Description of function shielding gas, which flows from the shielding-gas nozzle, which is positioned concentrically around the electrode. 3.3.18 The Special mode 3.3.18.1 General Description The operating panel enables the complete overview of the important settings for the both TIG and stick-electrode welding on the TIGER machine. In addition to this the numerous special parameters and functions in the special mode can also be set and altered according to the individual requirements.

Description of function 3.3.18.2 Pre-flow gas time ( A ) The pre-flow gas time is the time for which the gas solenoid opens after depressing the torch button 1 until the arc ignition cycle starts. This ensures that the tip of the tungsten electrode and the workpiece is protected from the atmosphere before the ignition takes place If during the gas post flow time the welding process is re-started, the processor automatically set the gas pre-flow time to „zero“.
Page 30
Description of function 3.3.18.7 Hot start ( H ) In order to improve the ignition when stick-electrode welding, the ignition current is given a short boost when starting. This hot start current is higher than the welding current that has been set (I1). The setting value for the hot start is a direct relationship to the welding current.
3.3.18.10 Dual-Wave ( F ) The Dual Wave process from REHM is a combination of AC and DC welding. The processor controls the welding process and automatically alternates the current from AC for 0.2 seconds to DC for 0.3 seconds. The selected values for the welding current I1 or I2, the frequency and the wave balance are applied as for DC-only or AC-only welding.
In the case that this LED flashes on and off then an internal fault condition has been recognised. This can be reset by power off and then on again. If fault cannot be cleared then please contact Rehm customer service (RKS).

Personnel who are trained in the use and maintenance of welding units and are familiar with the relevant safety regulations are the only persons who are qualified to operate REHM welding units. Working with and maintenance of electrical welding units always involves possible hazards.
Operation Personal safety instructions The action of the radiation of the electric arc or of pieces of the hot metal may lead to severe burns to the unprotected skin and eyes. Only use undamaged welder’s protective clothing, and eye protection with the correct protective filter glass: The use of leather gloves and a welder’s helmet to protect your eyes and body from sparks and radiation from the arc is essential (see BGR 500 [formerly VBG 15, §...
REHM TIG welding units. A suitable guideline is that for a given electrode the current is too high if it forms droplets or assumes a broom type structure.

Aluminium is heated. Since usually only a short positive pulse is needed in order remove the Aluminium oxide skin, a greater negative proportion can be used with REHM TIG units. This has a number of advantages: The temperature load on the electrode is reduced.
Page 45
Operation High-voltage ignition units are fitted as standard in the REHM Tiger machines in Ignition with and order to provide contact-free ignition of the welding arc. The high voltage without high electrically ionises the distance between the tungsten electrode and the frequency (HF) workpiece in such a way that the welding arc can bridge this gap.
Machine faults Troubleshooting Safety instructions WARNING! If a fault occurs which represents a risk to personnel, equipment and/or their surroundings; the equipment and all work MUST BE STOPPED immediately. It must also be ensured that it is not possible to turn on the equipment again until the fault is cleared and made safe.
