5.5 Overheating protection
When the machine is switched on with the mains switch, [1] or [3] depending on machine
model, indicator lamp [1] is on and lamp [2] off - the machine is ready to operate. If the
internal temperature becomes too high, the welding is interrupted and disabled. This
state is indicated by lighting of the orange indicator lamp [2] on the front of the machine.
It resets automatically when the temperature has fallen.
6 MAINTENANCE
Regular maintenance is important for safe, reliable operation.
CAUTION
All guarantee undertakings from the supplier cease to apply if the customer attempts any
work to rectify any faults in the product during the guarantee period.
6.1 Inspection and cleaning
Check regularly that the power source is free from dirt.
The power source should be regularly blown clean using dry compressed air at reduced
pressure. It should be cleaned more frequently in dirty environments. Otherwise the air
inlet/outlet may become blocked and cause overheating.
Welding gun
S The welding gun's wear parts should be cleaned and replaced at regular
intervals in order to achieve trouble-free wire feed. Blow the wire guide clean
regularly and clean the contact tip.
The brake hub
The hub is adjusted when delivered, if
readjustment is required, follow the instructions
below. Adjust the brake hub so that wire is slightly
slack when wire feed stops.
S Adjusting the braking torque:
S Turn the red handle to the locked position.
S Insert a screwdriver into the springs in the hub.
Turn the springs clockwise to reduce the braking torque
Turn the springs counter-clockwise to increase the braking torque. NB: Turn
both springs the same amount.
