Problem
Remedy
Reference
Lack of fusion to bore surface
Direct the arc at the precise intersection between the bore
surface and the previously laid weld deposit.
Increase rotation speed.
Section
5.3.1.1 on
page 71
Lack of fusion to the previous weld
bead of the same layer
Direct the arc at the precise intersection between the bore
surface and the previously laid weld deposit.
Increase arc voltage.
Section
5.3.1.2 on
page 71
Machine cannot be retracted or
extended
Check for motor failure.
Check for continuity of motor circuit (check the schematic).
Check cable for continuity.
Determine if worm roll pin is sheared or gear train is other-
wise damaged.
Section
5.3.2.2 on
page 74
Machine does not rotate
Verify motor continuity by checking BoreWelder receptacle
pins (check the schematic).
Check cable for continuity.
Section
5.3.2.3 on
page 75
Porosity in the weld
Protect shielding gas from contamination from bore surface
by lowering gas flow, preventing spatter buildup, cleaning
bore surface, and/or using stick welding on laminated sur-
faces.
Section
5.3.1.7 on
page 72
Too much spatter
Lower the arc voltage.
Section
5.3.1.5 on
page 72
Step: Machine does not step
Check that the step is enabled.
Check that the
STEP
switch is working properly.
Check the control cable for continuity. Check that the
RETRACT
and
EXTEND
buttons move the quill.
Section
5.3.2.1 on
page 74
Tip seizure
See “Wire feed: Wire feeding stops and wire burns back to
tip” in this table.
--
Voltage control: No voltage control
Check continuity of the power supply control cable.
Check positive and negative ground leads for proper con-
nection.
Section
5.3.2.7 on
page 75
Weld beads are ropey
Increase arc voltage.
Use less CO
2
in the shielding gas. Increase inductance.
Section
5.3.1.4 on
page 71
Weld breaks cutting tools when
machined
Hone the cutting edge of the tool.
Check that the nose radius is not too small or too large.
