9. Space subsequent welds apart from each other. Part or all
of the current may pass through the nearby weld instead of
creating a new weld.

TEST PROCEDURES

Conduct a test with scrap metal of the same thickness and type
to properly adjust the spot welder.
VISUAL TEST
Observe the deformation and shape of the surface contact
points at both sides of the weld. Excessive 'dishing' of the
surface contact point indicates one or more of the following:
1. Excessive tong pressure. Adjust the tong pressure to
increase the tong gap.
2. Time holding the power switch. Adjust the length of time
holding the operating lever down to create the correct weld.
3. If the resistance spot weld does not have an even,
concentric surface appearance, the problem could be
misalignment of the electrode tips. Align the electrode tips
with the power off.
MECHANICAL TEST
Place one end of the resistance spot weld sample in the vice jaws.
Use mechanical means to force the weld apart. The weld should
remain on one piece, with a matching hole in the other metal
piece. Check for proper weld diameter.
Once the spot welder is fine-tuned, proceed with the welding job.
CARE & MAINTENANCE
1. Maintain the tool with care. A tool in good condition is
efficient, easier to control and will have fewer problems.
2. Inspect the tool components periodically. Repair or replace
damaged or worn components. Only use identical
replacement parts when servicing.
