permissible workplace pollutant concentration. The fumes of lead, cadmium, copper, chromium, nickel, zinc and beryllium are particularly harmful! A Caution! • Never weld earthed metal. Welding earthed metal may cause damage to the protective earth conductors by stray currents. • Never use the welding machine for thawing pipes. • Always attach the earth cable directly to the weld metal and as close as possible to the welding spot. • Always carry the welding machine at the carrying strap when transporting it. • Special care is required when working near computers, electronically controlled equipment or in the proximity of magnetic data media (sound recording tapes, floppy disks, data recording tapes, credit cards, etc.). The arc start can cause misfunction of this type of equipment or data loss. 2.3 Symbols on the machine Arc welding with coated stick electrodes Tungsten Inert-gas Welding (TIG welding) XS0015E.fm Operating Instructions DEUTSCH Information on the rating plate: 2 3 4 5 7 6 1 1 Manufacturer 2 Machine designation 3 Serial number 4 Standard information – This machine meets the requirements of the standards mentioned here 5 CE mark – This machine conforms to the EU directives as per declaration of conformity 6 Electrical performance data 7 Year of make 3.

Preparing for Operation 4.1 Placing the machine A Caution! Always stand the machine on its feet only. >20 cm The machine draws in air at its front and bottom, which is given off through the ventilating slots at the rear. Ensure an unhindered airflow. The distance of the machine to walls or other equipment must be at least 20 cm. 5. Operation A Caution! Check all connections and supply lines before turning on. 3 Note: For manual arc welding this machine uses the Hot-start, Arc-force and Anti-stick functions. Hot-start function When contacting the weld metal with the electrode, the set welding current is increased for a short period to ensure that the arc will start. This brief increase of the welding current is limited to the maximum electrode current. Arc-force function During the welding process the machine keeps the energy (heat) brought into the weld metal at a constant level, even if the distance between electrode and weld pool varies. Anti-stick function If the machine detects a short-circuit in the welding process, it will switch to minimum current within 0.5 sec to keep ...
