Inching the wire electrode
CAUTION
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 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!
