Inspection and cleaning
Power source
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, see "CLEANING" chapter. This should be done 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. Order number can be found in the "ACCESSORIES" chapter.
Welding torch
The welding torch'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.
•
Adjusting the braking torque:
○ Turn the red handle to the locked
position.
○ 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.
Note:
Make sure you turn both springs
the same amount.
