WARNING
Risk of injury from electrical voltage!
Contact with live parts, e.g. power connections, can be fatal!
• Observe the safety information on the first pages of the operating instructions!
• Commissioning must be carried out by persons who are specifically trained in handling
power sources!
• Connect connection or power cables while the machine is switched off!
CAUTION
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.
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 es-
cape 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!
• Check wire guide at regular intervals!
• Keep all casing covers or protective caps closed during operation!
Read and observe the documentation to all system and accessory components!
5.1 Transport and installation
CAUTION
Risk of accidents due to supply lines!
During transport, attached supply lines (mains leads, control cables, etc.) can cause
risks, e.g. by causing connected machines to tip over and injure persons!
• Disconnect all supply lines before transport!
5.1.1 Ambient conditions
Equipment damage due to contamination!
Unusually high amounts of dust, acids, corrosive gases or substances can damage the machine
(observe maintenance intervals).
• Avoid large amounts of smoke, steam, oily fumes, grinding dust and corrosive ambient air!
5.1.1.1 In operation
Temperature range of the ambient air:
• -10 °C to +40 °C (-13 F to 104 F)
[1]
Relative humidity:
• up to 50 % at 40 °C (104 F)
• up to 90 % at 20 °C (68 F)
