WARNING
Risk of injury from electric shock!
Contact with live parts, e.g. welding current sockets, is potentially fatal!
•
Follow safety instructions on the opening pages of the operating instructions.
•
Commissioning may only be carried out by persons who have the relevant expertise of
working with arc welding machines!
•
Connection and welding leads (e.g. electrode holder, welding torch, workpiece lead,
interfaces) may only be connected when the machine is switched off!
CAUTION
Insulate the arc welder from welding voltage!
Not all active parts of the welding current circuit can be shielded from direct contact. To
avoid any associated risks it is vital for the welder to adhere to the relevant safety
regulations. Even low voltages can cause a shock and lead to accidents.
•
Wear dry and undamaged protective clothing (shoes with rubber soles/welder's gloves
made from leather without any studs or braces)!
•
Avoid direct contact with non-insulated connection sockets or connectors!
•
Always place torches and electrode holders on an insulated surface!
Risk of burns on the welding current connection!
If the welding current connections are not locked, connections and leads heat up and
can cause burns, if touched!
•
Check the welding current connections every day and lock by turning in clockwise direction,
if necessary.
Risk of injury due to moving parts!
The wire feeders are equipped with moving parts, which can trap hands, hair, clothing
or tools and thus injure persons!
•
Do not reach into rotating or moving parts or drive components!
•
Keep casing covers or protective caps closed during operation!
Risk of injury due to welding wire escaping in an unpredictable manner!
Welding wire can be conveyed at very high speeds and, if conveyed incorrectly, may
escape in an uncontrolled manner and injure persons!
•
Before mains connection, set up the complete wire guide system from the wire spool to the
welding torch!
•
Remove the pressure rollers from the wire feeder if no welding torch is fitted!
•
Check wire guide at regular intervals!
•
Keep all casing covers or protective caps closed during operation!
Risk from electrical current!
If welding is carried out alternately using different methods and if a welding torch and
an electrode holder remain connected to the machine, the open-circuit/welding voltage
is applied simultaneously on all cables.
•
The torch and the electrode holder should therefore always be placed on an insulated
surface before starting work and during breaks.
