6.2.5 Additional Warning – First Charge is Slow
This is intentional in order to give the operator a chance to adjust F67 as appropriate.
6.2.6
Additional Warning – Unit Fails to Charge
Fuse F2 is located in the 723-248-011 wire harness and meant to protect the charging circuit.
6.2.7 Additional Warning – Inconsistent Drop Times
1.
Eliminate excessive lift.
Too much lift increases the possibility of stud hang up.
2.
Be sure the weld energy is appropriate for the application.
3.
Inspect foot alignment.
Adjust if necessary. A misaligned foot will almost guarantee stud hang-up. Ensure
that the stud is centered within the ferrule.
4.
Inspect chuck.
Replace if necessary. Check for a good grip of the stud in the chuck. A good grip is
needed to eliminate slipping of the stud.
5.
Tighten foot-retaining screws.
These screws hold the foot in place during a weld while pressure is placed
on the foot. Slippage of the foot will lead to a faster drop time.
6.
Inspect and clean gun housing and related parts
. Replace parts as needed. Debris in the housing will
resist travel.
