N.B.! To interrupt the welding operation, simply lift the torch away from the
workpiece until the arc goes out. In this case, there will be no filling of the end-
crater at reduced current, and no gas-shielding of the end-crater.

CARE AND MAINTENANCE
Warning! Before opening up the welding machine, switch it off, unplug
it from the mains and put up a warning sign to stop anybody
inadvertently switching it back on again. If necessary, discharge the
electrolytic capacitors.
In order to keep your welding machine operational for years to come, you
should observe the following points:
- Carry out safety inspections at the stipulated intervals (see the section
headed "Safety rules")
- Depending on the machine location, but no less often than twice a year,
remove the side panels from the machine and blow the inside of the
machine clean with dry, reduced-blow compressed air. Do not aim air-
jets at electronic components from too close a range.
- If a lot of dust has accumulated, clean the cooling-air ducts.
