The extension arm electrodes can be easily removed by lightly tapping them
with a pin and hammer as shown in fig. 5.6
Removing Piston Electrode
To remove the piston electrode:
1. Grip piston electrode with a set of pliers or vise-grips (fig.5.6a).
2. Rock the pliers back and forth to loosen the electrode from the holder.
3. Remove the electrode
Note: Vise-Grips shown in fig. 5.6a are specially designed to hold round
objects without damaging or scarring them. You can purchase a set from your
local distributor or online at: www.prospot.com
IMPORTANT! Do not attempt to remove the electrode by hitting it.
This could damage the electrode and the spot gun.
