PRO WEL D
For CD welding, the stud normally should be
engaged for all but 1/4” of its length, whenever pos-
sible. Selecting the proper stop will accomplish this
for you. The objective of the collet is to maintain a
firm grip on the fastener to assure correct alignment
and a good electrical connection, yet allow for ease
of loading.
Once the selection of the correct accessory is
made, assembly may begin. The footpiece is
mounted on the legs using 10-32 x 3/4” socket head
cap screws, inserted through the holes at the base of
the footpiece. These holes are recessed so that the
head of the screws will not protrude.
After assembling the legs and footpiece, insert
the collet and stop into the open end of the gun shaft.
Secure the collet in place with two set screws on the
shaft. Locate the legs, with footpiece attached, in the

11.0 GUN SET-UP
11.1 STANDARD (see Figure 5)
The standard gun set-up is used for welding the
majority of applications. It consists of the standard
adjustable face plate, two legs, a foot, B-collet, stop,
and spring for your specific stud size.
A step-by-step explanation of the correct way
to set-up and operate the standard CD gun.
To prepare for stud welding, it is necessary to
have the proper accessories for the stud to be
welded. Those required are the legs, footpiece,
spring, collet, and appropriate screws and washers.
A 3/32” and a 5/32” hex wrench are the only tools
needed for the adjustment of the gun.
holes provided in the gun faceplate. (It
may be necessary to back off the
socket screw in the faceplate to allow
the legs to enter the hole). Center the
opening of the footpiece around the
weld end of the fastener. Tighten the
footpiece in position at this time. Ad-
justment for the plunge which is the
distance the stud protrudes beyond the
end of the footpiece can now be made.
This is done by loosening the two 10-
32 x 1/4” set screws at the bottom of
the faceplate using the 3/32” Allen
wrench. Then sliding the legs for
proper adjustment. Refer to the set-up
chart for correct plunge distance (from
1/8” to 5/16”).
NOTE:
Correct set-up on all CD units is
1/8”- 5/16” plunge. This must be as-
sured for proper weld results in all
cases.
