POWER SUPPLY COMPONENTS
The power supply features microcontroller electronics and
closed-loop circuitry to precisely control output current.
The software is accessible using the M100 operator display
and keypad or the remote keypad. The data recording
printer prints program information as well as welded
outputs. The PC card may be used to store weld data and
transfer data to a PC for QA/QC records.
Figure 1 Power Supply
The power supply uses screen-prompted software for weld
parameter control. See Figure 2. The appropriate settings
are generally defined by the work pieces to be welded and
are refined using test welds. The correct settings used for a
specific job are developed into a weld procedure guideline.
The guideline is used to maintain repeatability and quality
control for subsequent jobs of the same type.

3. Check the power supply and accessories for damage.
Check that a roll of thermal printing paper is installed
in the data-recording printer.
4. Check that the serial number on the rear panel of the
power supply matches the serial number on the
shipping container label.
5. Record the model number, serial number, and the
delivery date on the Registration Information page in
the Regulatory Module.
Installing the Power Supply
To get the maximum performance and reliability from
your SWS, it must be set up and installed properly.
To install the power supply, follow these steps:
1. Position the power supply so that the front and rear
panel controls are easily accessible.
2. Locate the power cord. Insert the cord into the
polarized receptacle on the rear of the power supply.
See Figure 3.
3. Tighten the connector lock at the base of the
receptacle to secure the cord in the receptacle.
4. Ensure that the power cord reaches an electrical outlet.
Do not connect the power cord to the outlet at
this time.

5. Turn off the power supply circuit breaker on the rear
panel of the unit. See Figure 4.
Figure 4 Turn Off Circuit Breaker
Installing the Weld Head
The weld head assembly has four connectors that plug
into the power supply. See Figure 5.
The four connectors on the cable are:
• Fixture
• Electrode (red)
• Work (green)
• Weld head shielding gas.

Connect the four connectors to the rear panel of the power
supply by performing the following steps (see Figure 6):
1. Locate the weld head assembly.
2. Align the notch on the multi-pin connector with the
small tab in the mating socket on the rear panel
labeled FIXTURE. Insert the connector in the socket.
Turn the connector sleeve clockwise by hand until it is
tight. This connection provides the control signals to
drive the weld head.
3. Insert and fully seat the red connector into the socket
on the rear panel labeled ELECTRODE. Twist the
connector 1/4-turn clockwise to lock it into place.
This connection is the negative (-) terminal of the
weld head.
4. Insert the green connector into the socket on the rear
panel labeled WORK. Twist the connector 1/4-turn
clockwise to lock it into place. This connection is the
positive (+) terminal of the weld head.
5. Insert the weld head shielding gas connector into the
Swagelok Quick-Connect stem labeled TO WELD
HEAD. Ensure that the connector is firmly attached.
This connection provides shielding gas to the weld
head through a solenoid valve in the power supply.
Figure 6 Weld Head Connectors
Caution!
Ensure that the fixture
connector is fully seated in
the mating socket and the
threaded sleeve is tight.
Note:
The weld head shielding gas
connector must be a single-end shut-
off (SESO) Swagelok Quick-Connect
stem (SS-QC4-S-400).

Installing the Gas Delivery
System
The gas delivery system provides shielding gas to the
weld head to reduce oxidation or contamination of the
weld puddle, tungsten electrode, and
Heat Affected Zone (HAZ).
There are two types of gas delivery systems commonly
used. For a typical gas delivery system, refer to the
installation procedure beginning on this page.
For a gas delivery system using a secondary shielding gas
solenoid valve, see Optional Gas Delivery System
beginning on page 9.
Typical Shielding/Purge Gas Delivery
System
Figure 7 shows a typical system. Be sure to adhere to the
following precautions:
• Ensure that the gas storage container(s) are
secured before using them.
• Ensure all connections are tight and do not leak.
• Use only a Swagelok single-ended shut-off
Quick-Connect stem on the shield/purge line for
the shielding gas connector.
• Adjust the low-pressure regulator gage to reduce
the gas storage container source pressure to 25 to
50 psig (1,9 to 3,5 bar).
When complete, continue to the Preliminary Check
procedure beginning on page 11.

Optional Gas Delivery System
The optional gas delivery system is generally used in Ultra
High Purity (UHP) gas sytems where quick connects are not
permitted. This type of system uses an external 12 V (dc)
secondary solenoid valve instead of using the solenoid valve
located inside the power supply. If necessary, the secondary
solenoid valve may be the high purity type.
A secondary solenoid bypass plug is inserted in the EXT
GAS CONTROL connector on the rear panel to disable the
solenoid inside the power supply and provide +12V to
control the secondary solenoid.
For the gas delivery system using a secondary shielding gas
solenoid valve, locate the:
• Secondary solenoid bypass plug
• Secondary shielding gas solenoid valve
• 1/4-turn internal purge gas shut-off valve.
Referring to Figure 8, install the optional gas delivery
system. Be sure to adhere to the following precautions:
• Ensure that the gas storage container(s) are secured
before using them.
• Ensure all connections are tight and do not leak.
• Observe correct polarity on the secondary solenoid
bypass plug.
• Adjust the low pressure regulator gage to reduce the
gas storage container source pressure to 25 to 50 psig
(1,9 to 3,5 bar).
Caution!
Do not insert the secondary
solenoid bypass plug into the
connector unless you are
using a secondary solenoid.
Inserting the plug disables
the power supply solenoid.
