6.5.3 Weekly Maintenance (40 Hours)
CAUTION:
Perform all electrical work with power secured.
1.
CABLE CONNECTIONS- Check all electrical lead connections from power supply to
wire feeder. The connections must fit firmly, a loose fit will cause the leads to heat up.
Use a screwdriver to spread the male prong for a tight fit.
2.
FEEDER CONNECTIONS- Check the fittings inside the feed unit, tighten all bolts that
connect the current to the wire feed assembly.
3.
POWER SUPPLY- Disconnect the power supply from the primary current. Remove the
side covers then remove the dust from inside the machine with an air hose.
