MISALIGNED WELD-BLADE ENDS ARE OVERLAPPED

(1) Jaw Upset Force Control set for wider blade than used, re-adjust correctly.

(2) Blade ends or jaws not aligned correctly

WELD BREAKS WHEN USED

(Joint is not complete, “blow holes” in joint)

(1) Weld not annealed correctly.

(2) Weld has been ground too thin.
(3) Weak “Incomplete” weld.

INCOMPLETE WELD

(Items 3

– 8 requires welder removal)

(1) Incorrect Initial Set-Up:

(a) Initial jaw gap (weld lever position) not set correctly.

(b) Upset force control not set correctly.

(2) Improper clamping procedures.

(3) Defective cut-off switch may not break the circuit at end of welding operation.

(4) Cut-off Switch not adjusted correctly.

(5) Points of cut-off switch welded together.

(6) Slide Rod sticking because of rust or dirt. Clean and oil the rod.

(7) Slide Rod movement obstructed because the stop screw too tight on the Rod.

(8) Jaw movement obstructed by kinked jaw cable or tangled wires. Bend cable and

untangle wires.

BRITTLE WELDS

Weld has not been annealed correctly; see “Annealing” in operation chapter. Poor

annealing can be caused by:

1. Incorrect annealing heat. Bring wel

d up to correct color as described under “Annealing”

in welder operations chapter.

2. Scale or oil on weld can cause poor annealing.

TROUBLE SHOOTING

PROBLEM

CAUSE

SOLUTIONS

The Weld could not be made,
the Jaws do not move

A. The wire connection is poor, the

connecting point of welding
switch is bad

B. The transformer is burnt out
C. Some oil is on the blade

D. Some rust is on the blade

ends

E. The adjustment of the welding

pressure is incorrect

A. Change the welding switch.
B. Change the transformer.
C. Remove the oil
D. Grind off the rust
E. Loosen the adjusting screw

that is in center of it

The weld area melts the blade
not welds it when welding
switch is pushed

A. The welding switch cut off too

late

B. The Welding Pressure is too

weak

C. The jaw movement is too slow

A. Screw the welding switch

Connecting Nut tight

B. Turn the welding pressure

adjuster clockwise

C. Put some oil on the rear side

of the welding lever jaws
