Electrode Care and Pressure
Touch the work piece to the electrode with very light
pressure. Too much pressure will cause the work piece
to stick to the electrode and cause the electrode to
become contaminated (work piece material on the elec-
trode). Sunstone recommends cleaning or changing the
electrode when it sticks to the work piece.
When to Sharpen the Electrode
Refer to Chapter 3 for more information on electrodes.
The majority of applications are best accomplished
using a sharp electrode tip. A sharp tip improves arc
initiation and helps focus the arc properly. It is recom-
mended that you pay close attention to the electrode
condition. An electrode that appears to be dark colored
or covered with material from previous welds can lead
to inconsistent welding and poor ignition of the weld
arc. When this occurs, simply sharpen the electrode
with the included diamond disk. The diamond disk can
be attached to a rotary tool. Follow these steps for
sharpening the electrode:
• Remove the electrode from the stylus.
• Pinch the electrode between the thumb and
index and/or middle finger with the shaft going
perpendicular to the fingers. See Figure 8.1.
• Power on the rotary tool then hold it with the
opposite hand.
• Place the electrode tip on the diamond disc so
the grit of the disk is moving parallel with the
electrode shaft and moving towards the tip. See
Figure 8.2. Sharpening the electrode in a way
other than explained here will affect the quality
of the weld.
• Set the electrode on the diamond disk at a
10-degree angle and begin to spin the elec-
trode with the thumb and middle finger. Tip:
A helpful way to get a sharp electrode is to
push down on the electrode with your index
finger while twisting the electrode with the
thumb and middle finger. See Figure 8.2
Figure 8.1. A sharp electrode tip improves arc initiation
and results in a better overall weld.
