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 5.1.2.1 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.
