6.2 Function explanation
6.2.1 Overheating protection
A thermal overload cutout protects against overheating. The cutout resets automatically
when the unit has cooled.
6.2.2 Inductance connection
Higher inductance produces a more flowing weld and fewer spatters. Lower inductance
produces a harsher sound and a stable, concentrated arc.
7 MAINTENANCE
Regular maintenance is important for safe, reliable operation.
Note!
All guarantee undertakings from the supplier cease to apply if the customer himself
attempts any work in the product during the guarantee period in order to rectify any
faults.
7.1 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. More frequently in dirty environments.
Otherwise the air inlet/outlet may become blocked and cause overheating. To avoid
this you can use an airfilter.
The airfilter is an accessory. Ordering number can be found on page 176.
Welding gun
S Cleaning and replacement of the welding gun’s wear parts should take place 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 anticlockwise to increase the braking torque.
NB: Turn both
springs through the same amount.
