1.3. OPERATION SAFETY
Never watch the arc without a face shield designed for arc welding!
The arc damages unprotected eyes! The arc burns unprotected skin!
Protect yourself and the surroundings against the arc and hot spray!
Remember general fire safety!
Pay attention to the fire safety regulations. Welding is always classified as a fire risk operation.
Welding where there is flammable or explosive material is strictly forbidden. If it is essential to
weld in such an area remove inflammable material from the immediate vicinity of the welding
site. Fire extinguishers must always be on site where welding is taking place.
Note! Sparks may cause ignition many hours after completion of welding.
Watch the mains voltage!
Take care of the cables - the connection cable must not be compressed, touch sharp edges or
hot work pieces. Faulty cables are always a fire risk and highly dangerous. Do not locate the
welding machine on wet surfaces. Do not take the welding machine inside the work piece (i.e.
in containers, cars etc.)
Ensure that neither you nor gas bottles or electricial equipment are in contact with live wires
or connections!
Do not use faulty welding cables. Isolate yourself by using dry and not worn out protective clot-
hes. Do not weld on wet ground. Do not place the welding cables on the power source or other
electricial equipment.
