Weld Head
The Series 20 SWS weld head delivers consistent, precise welds for outside tubing diameters from 1/2 to 2 in. and 12 to 52 mm and pipe diameters ranging from 1/4 to 1 1/4 in. and 10.2 to 48.3 mm.
A DC motor in the weld head drives a rotor, which carries the tungsten electrode around the weld joint. Optical circuitry in the weld head sends precise feedback to the power supply to control the speed of the rotor.
All moving parts in the weld head are mounted in low-friction devices to provide smooth, consistent operation.
A spring-loaded, floating brush continuously contacts approximately one-third of the circumference of the rotor. This configuration ensures consistent, uniform electrical conductance to the rotor and electrode.

Figure 1 Series 20 Weld Head

Fixture Block
The Series 20 SWS fixture block accurately aligns and holds tubing, fittings, and valve bodies. The modular design allows you to select different side plates and create the configuration needed for the job.
The fixture block is separate from the weld head, allowing work pieces to be easily aligned and fixtured before welding. Using multiple fixture blocks can increase productivity.
Each fixture block is designed to accommodate a range of work piece sizes. A Universal Collet Insert (UCI) fits into the fixture block to match the diameter of the work piece. The collet design firmly holds tubing and fittings that vary ± 0.005 in. (0,13 mm) from nominal outside diameter. Collets are also available for thin wall pipe. The collets exchange quickly, making the fixture block very adaptable to changing work requirements.

Installing the Weld Head
The weld head has four connectors that plug into the power supply.
The four connectors on the cable are: · weld head · electrode (red) · work (green) · weld head shielding gas
Connect the four connectors to the side panel of the power supply by performing the following steps (see Figure 4): 1. Locate the weld head. 2. Align the notch on the one-quarter turn connector with the small
tab in the mating socket on the side panel labeled WELD HEAD. 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 side 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 side 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 mass flow controller (MFC) in the power supply.

Setting the Arc Gap
The proper arc gap setting facilitates control of the weld and improves consistency. The following steps cover how to set the arc gap. The arc gap is set by using the arc gap gage provided with the weld head. The gage is adjusted for the desired arc gap and then installed in the rotor. With the gage in place, the electrode can be positioned with reasonable accuracy.
Setting the Arc Gap Gage
1. Measure the outside diameters of the work pieces being welded using a caliper or micrometer. See Figure 8(A). The M200 will calculate the arc gap gage setting automatically when using the Auto Create feature.
2. Refer to the tables on page 10 for your nominal OD. Find the “actual” outside diameter nearest to your measurement.
3. Adjust the arc gap gage to match the setting from the tables on page 10. See Figure 8(B).

Preparing the Work
It is important to prepare the tube pieces properly before welding. Refer to Figure 11.
Tubing must be square and burr-free to ensure repeatable, highquality autogenous fusion welds. Cut the tubing to length with a hacksaw or tube cutter. Face the tube ends with a lathe or a portable facing tool. Deburr the ends, making sure that both the inside and outside diameters are square and burr-free. Clean the tube ends using an appropriate solvent.
Minimize the chance of a poor quality weld by following these guidelines:
· Tube ends must be square. · Tube ends must not have a wall thickness variation exceeding ±
15 % of nominal. · Tube ends must be burr-free. · Tube ends must be free of any rust, grease, oil, paint, or other
surface contaminates.
