Keep a fire extinguisher near the
welding area.
Check the welding area for fire af-
ter welding (see UVV*).
Never try to disassemble the pres-
sure reducer. Replace the defec-
tive one.
The machine must be transported
or set up only on firm, level surfaces.
The maximum admissible angle of
inclination for setting up or trans-
porting is 10°.
‰ Service and repair work may only be car-
ried out by a trained electrician.
‰ Ensure that the ground cable has good
and direct contact near the welding loca-
tion. Do not allow welding current to pass
through chains, ball bearings, steel cables
or grounding equipment; this may melt
them.
‰ Secure yourself and the welding machine
when working in elevated or inclined ar-
eas.
‰ The machine may only be connected to a
properly grounded mains supply. (Three-
phase four-wire system with grounded
neutral conductor or single phase-three-
wire system with grounded neutral con-
ductor) socket and extension cable must
have a functional protective conductor.
‰ Wear correct protective clothing, leather
gloves and leather apron.
‰ Protect the welding area with curtains or
mobile screens.
‰ Do not use this machine to thaw frozen
water pipes or cables.
