MAINTENANCE
1. Control box PEG1, see manual 443 392.
2. Motor with gear A6 VEC, see manual 443 393.
3. Daily
Clean any flux and dust off moving parts of the automatic welding machine.
S
Make sure that all electrical cables and hoses are undamaged and properly
S
connected.
Make sure that all bolted joints are tight.
S
Check the braking torque of the brake hub. The resistance should not be so
S
small that the wire reel continues to rotate when wire feed is stopped and it
should not be so high that the feed rollers slip. The recommended torque for
a 30 kg reel of wire is 1.5 Nm.
Adjusting the braking torque:
G
a. Set the locking button (006)
to the locked position.
b. Insert a screwdriver into the
hub springs.
Turning the springs (002) clockwise reduces the braking torque.
Turning them anticlockwise increases the torque.
NOTE! Turn each spring the same amount.
4. Periodically
Every three months check the condition of the motor brushes and replace
S
them when they are worn down to 6 mm.
Inspect the slides and lubricate them if necessary.
S
Check the electrode guides, drive rollers and contact tip of the wire feed unit.
S
Replace any components that are worn or damaged.
