MAINTENANCE

1. Control box PEG1, see instruction manual 443 392.
2. For conversion from Sub--arc to MIG/MAG see conversion kit 413 526--880.
3. Daily
Clean flux and dirt off moving parts of the welding machine.
S
Check that the contact tip and all electrical cables are connected.
S
Check that all bolted joints are tight and that guides and drive rollers are not
S
worn or damaged.
4. Periodically
Check the wire feed unit wire guides, drive rollers and contact tip.
S
Replace worn or damaged components.
(See wear components on page 123)
Check the slides and lubricate if stiff.
S
Lubricate the chain
S
5. Tensioning the carriage chain between front axle and rear axle.
Remove the carriage wheels. Undo the Y--flange bearing bolts.
S
Tension the chain by moving the rear axle backwards so that it remains par-
S
allel with the front axle.
Reassemble in reverse order.
S
6. Tensioning the carriage chain between the front axle and drive motor with gear.
Tension the chain by moving the drive motor and gear.
S
7. Check the brake hub braking torque. It should not be so low, that the wire reel
continues to rotate when wire feed is stopped and it should not be so great that
the feed rollers slip. As a guide, the braking torque for a 30 kg wire reel should
be 1,5 Nm.
Adjusting the braking torque:
S
Set the locking button (006)
S
to the locked position.
Insert a screwdriver into
S
the hub springs. Turning the
springs (002) clockwise
reduces the braking
torque. Turning the springs anticlockwise increases the torque.
NOTE! Turn the springs by the same amount.
