The torch is very flexible and lightweight, i.e. it allows convenient and fatigue-free use in all welding positions also for longer welding processes. For current decrease when welding in awkward positions, a switch is installed in the pistol-grip handle in order to keep the weld pool under control.

Please check manufacturers’ recommendations for your individual application! We recommend the following procedure for drying electrodes: • put the electrodes in a pre-heated oven (approx. 80 - 100 °C); max. number of layers: 3 • after pre-heating, keep the recommended temperature for approx. two hours; in case of drying temperatures over 250 °C, raise the temperature slowly (approx. 150 °C/h) to the recommended value • do not exceed a total drying time of 10 hours (this maximum value applies also if the drying process is made up of several cycles) • before you take the electrodes out of the oven, the temperature should be lowered to 70 – 90 °C. Do not weld with electrodes that were in direct contact with water, grease or oil. Drying such electrodes does not yield fully satisfying results, so these electrodes should only be used for minor purposes. Coated electrodes supplied in cans need no drying, if they are immediately put into the case and kept there during the welding process. Although we do not recommend drying of certain stick electrodes (see table above), it can be useful under certain circumstances to dry such electrodes too, for example, if electrodes were stored improperly or if other conditions led to too much moisture in the electrodes. A high water concentration usually can be identified during welding if increased splashing or porosity occurs. In such cases as described, stick electrodes may be dried for approx. one hour at 100 - 120 °C, if no other recommendations are given by the manufacturer. However, this does not apply to cellulose-coated stick electrodes, which generally must not be re-dried! The temperature for intermediate storage in an oven after re-drying should be 120 - 200 °C (for max. 30 days), for storage in a case 100 - 200 °C (for max. 10 days). 7E- 8 Worldwide expertise through more than 30 years experience 03/ 2008 - © VI ETZ Gmb H 2008 - Spec ific ations subjec t to c hange.

The core is largely protected against the ambient atmosphere by means of a metal band. However, it is possible that the low-hydrogen character of a flux-cored wire can be affected by moisture due to intensive contact with moist air, for example caused by unprotected overnight storage in an area with high air humidity. on the weld seam at the beginning of the welding process. Work with acclimatized wire only! When you have finished the welding process, remove the spool with the remaining wire from the machine and put it back into the original packing. Flux-cored wire should be stored in closed, dry and, if need be, heated rooms to allow for proper conditions with regard to temperature and humidity. We recommend a maximum of 60 % relative air humidity and at least 15 °C ambient temperature. If flux-cored wire is stored below 10 °C, it is possible that the surface of the wire is affected by condensed water when the packing is opened in a heated room.
