CD 80 Stud Welder
WELD QUALITY
Stud Welded Joint Quality
• A GOOD weld is determined by bending the stud back and forth.
Failure should occur in the stud shank or workpiece, not in the weld.
• HOT weld shows excessive splatter — adjust voltage downward
(see 6. A. below).
•
COLD
weld shows little or no splatter and may have a void
between the stud and workpiece — adjust voltage upwards.
(see 6. B. below).
6. Adjust the weld voltage up or down until a satisfactory weld is
consistently achieved.
A. When adjusting voltage
downward
, (e.g. from 100 V to 80 V) it
is necessary to turn the power off. Then turn the voltage selector
knob counterclockwise, turn the power back on, and increase to
the required voltage.
B. To adjust the voltage upwards (increase weld heat), turn the
voltage selector knob clockwise in small increments to a higher
setting.
When weld quality is consistently satisfactory, the CD 80 is properly
installed and setup.
