BODY STOP GAUGE SETUP:

Once the desired Pin Vise electrode stick-out is determined, set the

Body Stop Gauge as follows:

Initial Gauge setup:

1) With electrode extending to the desired length, tighten Pin Vise

lock collar.

2) Loosen Nut D on the Body Stop Gauge.

3) Insert electrode into Body Stop Gauge.

4) Rotate Knob C until the Stop makes contact with electrode tip.

Lock the Stop in place with Nut D.

To duplicate electrode Tip Flat diameter (with Body Stop Gauge depth set per above):

1) Insert electrode into Pin Vise. Extension should be beyond the desired final length.

2) Adjust Pin Vise collar so there is a slight drag on the extended electrode.

3) Insert electrode into Body Stop Gauge. Slide until nose of the Pin Vise contacts the Gauge face.

4) Secure electrode in position by tightening Pin Vise collar.

NOTE: Diamond Ground Products (DGP) Diamond Grinding wheels

are specifically designed for optimum wheel life for grinding tungsten

electrodes.

GRINDING TECHNIQUES

After the short set up procedure is finished you are ready to prepare

your electrode quickly and easily. Turn the power switch on; slide the

tungsten into the proper collet hole on the universal collet. From top

to bottom the holes are: 3/32"/2.4mm, 1/16"/1.6mm, .040"/1.0mm.

Lightly touch the wheel with the tungsten and rotate it in your fingers

in a steady manner until you have ground to a point or left the proper

sized flat you desire. Be patient and do not gouge the wheel by trying

to grind the electrode too quickly. Gouging the wheel will wear a

groove much faster and cause excessive wear. The approximate

recommended grinding times for each of the diameters is:

3/32" / 2.4mm

15 seconds

1/16" / 1.6mm

8 seconds

.040" / 1.0mm

5 seconds

REMOVING A TIP FROM AN ELECTRODE

After welding, it is beneficial to remove a bad tip before regrinding.

To do this, turn on the power and insert the tungsten in the proper

sized hole from the choices you see on the Tip/Flat Block. Slowly

push the tip against the wheel until the point is removed. Once again,

be patient and do not gouge the wheel. A burr can form if too much

pressure is exerted on the tungsten.
