SAFETY
PRECAUTIONS • Comply with all electrical, fire and other applicable codes or ordinances
in the installation and use of stud welding systems.
• Remove all combustible or volatile materials from the weld area.
Although weld splatter resulting from stud welding is normally minimal,
proper precautions should be taken when welding near or through
combustible materials to insure that sparks or weld material do not come
in contact with combustible material.
• Recommend wearing of eye protection at all times when welding.
Spectacle type frames with Shade No. 3 absorptive and filter lens and
side shields are suggested. Never look directly at the weld arc without
wearing eye shields.
• Recommend use of proper ear protection with all CAPACITOR
DISCHARGE stud welding systems. The stud welding operator and
anyone working within five (5) feet of the stud welding operation should
use ear protection devices.
• Use of protective clothing is suggested. Type of clothing will vary as to
application, weld position and stud welding being used; however, in all
cases, it should be fire resistant and sufficient to protect welding
operator from weld splatter and material.
• Keep hands, clothing, etc. away from the weld stud, chuck and all other
parts in contact with them during the weld cycle.
• Keep weld cable and connectors in good condition. Inspect periodically
for broken insulation and/or other electrical hazards.
• Do not operate with worn or poorly connected cables. Inspect all cables
often for bare or exposed wires, broken insulation layers and/or loose
connections. Repair all such connections before welding use.
• Do not stand in water or on damp surfaces while welding. Avoid wearing
wet or sweaty clothes. Do not weld in the rain.
WARNING
Use extreme caution when servicing or troubleshooting
any component of this stud welding system.
If possible, turn all power controls “OFF”
and disconnect all electrical cables.
For other suggested precautions, safe practices, etc.
regarding welding, refer to
“Safety in Welding and Cutting”,
ANSI Z49.1, American National Standards Institute.

Stud welding is a welding process where a “stud” (or similar metal part) is
instantaneously end-joined to a metal workpiece. This process involves the
same basic principles and metallurgical aspects as any other welding
process.
The equipment required to stud weld is composed of a direct current power
supply, a controller, a weld gun and cables to tie the system components
together. In most systems the power supply and controller are combined into
one unit called the “Welder.”
CD 100 STUD WELDING SYSTEM (P/N: CDSW-100-01)
The stud welding process is as follows. The stud is placed in the collet of the
“Weld Gun” and then positioned against the workpiece. The weld gun trigger
is depressed and t
hrough operation of the stud welding controller and the
design of the stud, an arc is drawn which melts the base of the stud and a
proportionate area of the workpiece.The stud is then forced by the weld gun
into the molten pool and held in place until the metals resolidify. This high
quality fusion weld is completed in milliseconds.
There are two different stud welding processes:
• Capacitor Discharge (called “CD” for brevity) and
•Arc.
The difference between these two methods involves the power source used
to provide the welding current, the workpiece size, base material and the
stud design.

CD STUD WELDING The CD stud welding process produces weld power through a rapid
discharge of the stored energy from a bank of capacitors.This stored
energy is usually derived from a standard 115 volt AC source. CD stud
welding, as a general rule, is used for studs 5/16" and less in diameter,
(or where thin base metals or dissimilar metals are to be joined.)
“CD”STUD WELDING PROCESS
The ARC stud welding process produces weld power through one of three
standard DC welding power sources. These are Transformer-Rectifier type,
Motor/Generator type, or Storage Battery type.A ceramic ferrule is
required in ARC stud welding to maintain the proper atmosphere in the
weld area. ARC stud welding is generally used for studs over 1/4" in
diameter or where heavier base metals are involved.
“ARC”STUD WELDING PROCESS
ARC STUD WELDING
1. Stud is placed against workpiece
and weld gun trigger depressed 2. Stored energy is discharged through special tip
3. Weld gun forces stud
into molten metal 4. Weld solidifies in miliseconds
1. Stud is placed against workpiece
and weld gun trigger depressed 2. Stud is lifted by weld gun and initiating arc is drawn
3. Weld gun forces stud
into molten metal 4. Weld solidifies and ferrule is removed

OVERVIEW – CD100
CAPACITOR DISCHARGE
STUD WELDER
The CD100 is a capacitor discharge stud welder. The weld energy is stored
in capacitors located inside the control unit. The amount of stored energy
can be controlled by rotating the voltage control knob located on the front
panel.
CD weld studs, or pins, used with the CD100 must have a specially
designed projection at the weld end. When the stud
is inserted into the weld
gun and placed against the workpiece
, and the trigger switch is depressed,
the following occurs:
1. The energy stored in the capacitors travels through the weld cables to
the stud.
2. The rapid rise in current ignites the projection and allows a welding
arc to be established between the stud and the workpiece.
3. The arc melts the base of the stud and a portion of the workpiece.
4. The spring pressure inside the welding gun forces the stud into the
molten metal pool created by the arc.
5. The cycle ends upon contact of the stud to the workpiece.
6. The welding gun is then removed. Upon removal, the controller will
automatically recharge to the set voltage.
CAUTION
The noise generated by stud welding
may exceed allowable levels
established by O.S.H.A. For this reason
it is recommended that proper ear protection be worn
by the operator and anyone working in the immediate area.
WARNING
Voltages inside the unit can reach 200 volts D.C.
even if the unit is turned off. All repair work
should be handled by factory trained personnel.

CD100 SETUP After installation, two setup phases must be completed before welding can
begin. These phases are:
• Weld Gun Setup, and
• ControllerAdjustment.
Your weld gun setup will depend on your application and the particular
stud to be welded. Setting up the gun consists of the following:
1. Locate the pins (or studs) that were shipped for your job and place a
pin into the weld gun Collet with the “weld tip” protruding. Push this
pin in until it seats firmly, assuring that the flange (or collar) of the
weld end does not come into contact with the collet.
2. Make sure that the gun “setup” accessories that came with the CD 2P
weld gun are adjusted properly and fastened tightly. Illustrations on
the following pages for:
• Insulation Pins (Figure 1)
• Insulation Pins with Internal Stop (Figure 2)
• Weld Studs (Figure 3)
• Weld Studs with Template Adaptor (Figure 4)
NOTE: These components may need to be readjusted, or changed, as
your job requirements change.

setup properly for your application, the final step is to adjust your stud
welding controller to the proper settings.
1. (Before turning on power) turn the controller VOLTAGE selector
switch to “MIN” (fully counterclockwise.)
2. Turn the controller ON/OFF switch to “ON.” Verify by observing
“POWER” lamp.
3. Using the chart below, adjust the “VOLTAGE” control until the
“WELDVOLTAGE” meter reads the desired value.
The chart settings shown below are "reference" settings to be used as
starting points. Actual voltage settings may vary depending upon the
conditions or each application and use. The voltages shown also assume
that the following are in use (as described in previous Installation and
Setup sections of this manual.)
A)
Straight polarity cable set ups in use (Gun = Negative, Ground = Positive.)
B) Ground connection directly to the part to be welded and connected in
a clean, solid manner.
C) 1/8" protrusion of pin/stud onto work (3/16" for Aluminum) causing
an equal amount of spring pressure in the gun.
D) “Silver” gun spring for Mild or Stainless Steel, “Black” for
Aluminum applications.

4. Pick up the weld gun and place the stud firmly against the workpiece
(The test workpiece should be a material that is similar to the
workpiece to be welded to in actual production.)
5. Depress the weld gun trigger, wait momentarily, and then pull the gun
straight back off the stud.
6. Test the weld integrity (see below.)

WELD QUALITY Stud Welded Joint Quality
•AGOOD 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 7. A. below).
•COLD weld shows little or no splatter and may have a void
between the stud and workpiece — adjust voltage upwards.
(see 7. B. below).
7. 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 100 is properly
installed and setup.

PREVENTIVE
MAINTENANCE
TROUBLESHOOTING
Your MIDWEST FASTENERS welder is designed for long service with
minimal care. Ordinary common sense maintenance will keep it operating
efficiently. The following are a few tips on preventive maintenance.
1. Treat the cables with respect. Avoid sharp bends or kinks which may
break the cables. DO NOT use the cables as a “towline” to drag or lift
the controller. Avoid damaging or straining the cables where they
enter the gun or controller.
2. Louvers on the sides of the controller should be free from
obstructions at all times to prevent overheating.
3. Keep the controller and gun clean and dry, free of grease, water, dust
and dirt. Do not lubricate any part of your CD2P weld gun.
4. The weld gun is for welding studs only. Do not use the weld gun as a
multipurpose tool (i.e., Hammer—banging studs to test welds or
break ferrules, Scraper—removing rust, scale or weld splatter, etc.)
When troubleshooting the CD100, the following precautions must be
observed.
1. Controller power must be TURNED OFF!
NOTE: Dangerous voltage levels can still be present in the
controller—even after power is disconnected.
2. The use of a volt/ohmmeter is recommended to verify where any
voltage may, or may not, be present.
3. The use of a continuity tester (or trouble shooting light) can be used
for continuity checking (disconnected) cables only.
The troubleshooting chart on the following pages can assist in locating and
fixing problems with the CD100.
