5.2.2 Connecting the supply lines
WARNING
Risk of injury from electrical voltage!
Touching live parts, such as welding current sockets, may be fatal.
• Note the safety information on the first pages of the operating instructions.
• Only personnel with the appropriate knowledge of handling arc welding equipment may
carry out the commissioning.
• Attach the connection or welding leads (such as electrode holder, welding torch, workpiece
lead, interfaces) only when the machine is switched off.
Overloading the coolant pump!
The cooling unit must not be put into operation without a welding torch connected, as otherwise
the coolant pump will be destroyed due to thermal overload (the coolant cannot circulate in the
coolant circuit).
• Connect the coolant connections for the water cooled welding torch to the cooling module.
• If air-cooled welding torches are used, the control and supply line between the cooling mo-
dule and welding machine must be disconnected!
Coolant connections
• Plug in the welding torch coolant connections and fit tightly onto the rapid-action closure couplings:
red rapid-action closure coupling
→
return of coolant from the welding torch
blue rapid-action closure coupling
→
supply of coolant to the welding torch.
Control and supply lead to the welding machine
• The cooling module and welding machine are connected using two leads.
• Insert control lead plug into the welding machine.
• Insert supply lead plug into the welding machine.
5.3 Transport and installation
WARNING
Risk of accident due to improper transport of machines that must not be lifted!
Do not lift or suspend the machine! The machine can drop and cause injuries! The
handles, straps or brackets are suitable for transport by hand only!
• The machine must not be suspended or lifted using a crane.
5.3.1 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!
5.3.2 Ambient conditions
The machine must not be operated in the open air and must only be set up and operated on a
suitable, stable and level base!
• The operator must ensure that the ground is non-slip and level, and provide sufficient lighting
for the place of work.
• Safe operation of the machine must be guaranteed at all times.
Equipment damage due to contamination!
Unusually high amounts of dust, acids, corrosive gases or substances can damage the machine
(observe maintenance intervals > see 8.2 chapter).
• Avoid large amounts of smoke, steam, oily fumes, grinding dust and corrosive ambient air!
