| SAFETY PRECAUTIONS | SENSE LEAD FUSE |
|
WARNING
ELECTRIC SHOCK can kill.
• Only Qualified personnel should perform this maintenance.
•Turn the input power OFF at the disconnect switch or fuse box before working on this equipment.
•Do not touch electrically hot parts.
There should never be any current flowing through the sense leads! There is a fuse located in the sense lead circuit that is mounted in the wire drive Connection Box which protects the sense lead circuit from weld current due to incorrect configuration. If this fuse ever opens, check the sense lead configuration to ensure proper connections. The fuse must be replaced with a comparable fuse with a rating of less than 1 amp before welding. The fuse being open or missing would have the same effect on the welding as having a disconnected sense lead.
ROUTINE MAINTENANCE
•Check weld cables, control cables and gas hoses for cuts.
•Clean and tighten all weld terminals.
•Inspect and clean drive rolls and inner wire guide and replace if worn.
PERIODIC MAINTENANCE
•Every six months check the motor brushes. Replace them if they are less than 1/4" long.
•Every year inspect the gearbox and coat the gear teeth with a
CALIBRATION SPECIFICATION
All calibration is factory set on the Power Feed 10S.
To verify the wire feed speed:
•Press the INCH DOWN switch and adjust the wire feed speed to 100 in/min (2.54m/min).
•Measure the actual wire feed speed with a calibrated wire feed speed tachometer.
•The measured wire feed speed should be within ±2% of the set value.
