5.1.3
Machine cooling
Insufficient ventilation results in a reduction in performance and equipment damage.
• Observe the ambient conditions!
• Keep the cooling air inlet and outlet clear!
• Observe the minimum distance of 0.5 m from obstacles!
5.1.4
Workpiece lead, general
CAUTION
Risk of burning due to incorrect welding current connection!
If the welding current plugs (machine connections) are not locked or if the workpiece
connection is contaminated (paint, corrosion), these connections and leads can heat up
and cause burns when touched!
• Check welding current connections on a daily basis and lock by turning to the right when
necessary.
• Clean workpiece connection thoroughly and secure properly. Do not use structural parts of
the workpiece as welding current return lead!
5.1.5
Welding torch cooling system
Insufficient frost protection in the welding torch coolant!
Depending on the ambient conditions, different liquids are used for cooling the welding
torch > see 5.1.5.1 chapter.
Coolants with frost protection (KF 37E or KF 23E) must be checked regularly to ensure that the
frost protection is adequate to prevent damage to the machine or the accessory components.
• The coolant must be checked for adequate frost protection with the TYP 1 frost protection
tester .
• Replace coolant as necessary if frost protection is inadequate!
Coolant mixtures!
Mixtures with other liquids or the use of unsuitable coolants result in material damage and
renders the manufacturer's warranty void!
• Only use the coolant described in this manual (overview of coolants).
• Do not mix different coolants.
• When changing the coolant, the entire volume of liquid must be changed.
Dispose of the coolant in accordance with local regulations and the material safety data sheets.
