Fixture Block Daily Maintenance
At the start of each workday:
1. Inspect the fixture block for cleanliness, wear and damage.
See Figure 27.
2. Remove dirt, carbon, and vapor deposits from the fixture
block with a clean, soft cloth. A solvent such as alcohol or
acetone can be used. Remove heavier deposits with a fine-
grit abrasive pad.
At the end of each workday, clean and then store the fixture
block in a dry place.
Fixture Block Periodic Maintenance
Every 1,000 to 1,200 welds:
1. Inspect and clean the collets. See Figure 27(A).
2. Check for scratches and dents.
3. Remove dirt and oxides from all surfaces of the collet with a
soft stainless steel wire brush.
4. Remove any oxides from the non-anodized mating surfaces
of the side plates with a fine-grit abrasive pad. See
Figure 27(B).
5. Remove any dirt and oxides from the inside surfaces of
the side plates with a clean, soft cloth. See Figure 27(C).
Remove heavier deposits with a fine-grit abrasive pad.
6. Check the lever cam and latch for smooth operation. See
Figure 28.
a. Remove lever cam by removing the set screw from the
latch and pulling the lever cam from the fixture block.
b. Clean the lever cam and lightly lubricate if necessary.
c. Replace the set screw and verify that it is locked tightly in
position.
7. Verify the fixture block will properly secure the work piece.

b. Insert nominal sized tubing and close the fixture block
using the lever cams.
c. Verify the tubing does not rotate in the collets.
