Page 21: Electrode Welding
Functional description 3.5.4 Electrode welding The welding parameters for electrode welding are described in chapter 3.10. The electrode is both an arc carrier and additional material at the same time. It consists of an alloyed or non-alloyed core wire and a sheathing. The sheathing has the job of protecting the melt bath from the damaging introduction of air, and stabilising the arc. -

Page 24: Welding Current I2
Functional description 3.6.7 Welding current I2 Welding current I2 is set as described in Chapter 3.6.1. The use of welding current I2 is only meaningful for TIG welding, and is therefore only displayed if TIG welding is taking place. Welding current I2 is used when pulsing (see chapter 3.9.1) and when two-current control is being used: Two-current control: General method of operation:... -
Page 25: End Crater Current
Functional description Manual pulsing: If torch button 1 is pressed during the downslope time with the TIG 2-step function, the welding current immediately jumps to the value used during welding. Depending on the point in time during the downslope time the torch button is pressed, the energy mid-point can be selected directly and is infinitely variable. -

In order to ignite the arc, the electrode is applied and the torch button is pressed. When the electrode is raised, the arc ignites under program control and without wearing the sharpened electrode. -
Page 35: I2 Pulse Time T2
Functional description Hyperpulse: with pulse frequencies of 10 Hz to 15 kHz The course of the welding current corresponds to conventional pulsing. However, the periods of time for which currents I1 and I2 respectively are active are always the same. Since these time periods are extremely short, it is meaningful and normal to refer to them as pulse frequencies. -

Page 64: Operation
Warning! REHM welding units may only be operated and maintained by persons who have been educated and trained to operate and maintain welding units. Working with and maintaining electrical welding units always carries slight dangers. -
Page 65: Fire Prevention
Operation Inform people standing by of the dangers of the arc rays and the hot metal sparks and protect them using a shield that is not flammable. Pressurised gas bottles also present a potential danger. Strictly observe the safety regulations of the relevant professional authorities and the suppliers. -
Page 66: Practical Notes
Remember that the values specified there are calculated with machines that do not have the balance range of the REHM TIG units. The guideline is that the current is too high for a given electrode if it drips or has a broom-like structure. - Page 67 During the negative half wave, the electrode cools down and the aluminium is heated. Since tearing the aluminium oxide skin only need a short plus impulse, REHM TIG units can use a high minus proportion.
- Page 68 Welding stick REHM TIG units are, thanks to their fast and precise regulation dynamics, ideal electrodes current sources for electrode welding. The current level and polarity to be set is specified by the electrode manufacturers.
