5.1.6 Welding torch cooling system
Material damage due to unsuitable coolants!
Unsuitable coolant, coolants mixed with other types / liquids or use in an unsuitable tempera-
ture range will result in material damage and loss of the manufacturer's warranty!
• Operation without coolant is not permitted (dry running will destroy the coolant pump)!
• Only use the coolants described in these instructions for the specified ambient conditions
(temperature range) > see 5.1.6.2 chapter.
• Do not mix coolants of different types (including those described in these instructions).
• When changing the coolant, all liquid must be replaced and the cooling system flushed.
Dispose of the coolant in accordance with local regulations and the material safety data sheets.
5.1.6.1 Functional characteristics
The cooling system of this machine series is designed to optimise the operating conditions and is tempe-
rature- and flow-monitored to protect against damage. Limit values
> see 8.1.1 chapter
for warnings and
errors in the machine (adjustable depending on control system) are stored for monitoring and control of
the cooling system. If the cooling system is faulty or overloaded, an error message appears and the
welding process is switched off in a controlled manner.

5.1.6.3 Maximal hose package length
All information relates to the total hose package length of the complete welding system and presents
exemplary configurations (of components of the EWM product portfolio with standard lengths). A straight
kink-free installation is to be ensured, taking into account the max. delivery height.
