Series 4 Micro Weld Head
Disassembly and Cleaning
Use the following instructions to disassemble the micro
weld head for cleaning. Refer to the exploded view in
Figure 6-22 for part references.
1.
Lay the micro weld head down on a clean, dry surface
with the model and serial numbers facing up.
2.
Remove the five screws from the weld head housing.
See Figure 6-22(A).
3.
Rock the housing gently to loosen it from the rest of the
assembly. Lift and remove the housing.
4.
Remove the rotor by lifting it clear of the lower portion
of the micro weld head housing. See Figure 6-22(B).
5.
Loosen the electrode clamping screw, then remove the
electrode and ceramic insert. See Figure 6-22(C).
6.
Clean the rotor with the provided stainless steel
wire brush.
7.
Clean the ceramic insert with the provided nylon brush.
8.
Remove and inspect the two idler gears for damage.
Replace if necessary. See Figure 6-22(D).
9.
Clean the two idler gears with a solvent and a soft cloth.
10. See Figure 6-23(A). Hold the micro weld head as
shown. Gently lift the brush from the side noted in the
figure and rotate it outward a few degrees.
11. Note the position of the spring in the groove in the weld
head brush. The spring ends bend toward the brush
when the spring lays in the groove. Remove the spring.
See Figure 6-23(B).
12. Clean any oxide deposits from the weld head brush with
the provided stainless steel wire brush.
13. Inspect all other weld head components and clean any
that are dirty. Blow any loose dirt from the weld head
