1/8" Opposed Electrodes Installation Procedure - SUNSTONE MICRO E User Manual

• Lock the electrodes in place by tightening the screws on the front of the electrode holder (check to
make sure the position does not change while tightening.
• Remove the block and position the weld head such that the tips of the electrode hover between 1/8"
and ¾" above the surface of your work piece height (it can be useful to use pre-measured set-up
blocks).
• Once the desired height is achieved, tighten the T-Handle knobs.
Step 4: Adjust the Gap Between Electrode Halves
• Turn the thumb screw on the right side of the electrode holder counterclockwise to increase the gap
between the halves of the electrode until the desired gap distance is reached (use a feeler gauge or
spacers to set the gap consistently each time).
• Sometimes if a very small gap is desired, a piece of paper or business card can be inserted between
the electrode halves to help act as a spacer (tighten the thumbscrew until the paper is sandwiched
between the two halves).
1/8" Opposed Electrodes Installation (Optional Accessory Required) (Item #EL125RWMA)
Step 1: Position Electrode Clamp Plates
• Loosen the two screws on the front of the electrode holder. Reference Figure 8.3.
• Rotate and position the brass electrode clamp plates with the "half moon" shape facing inward toward
each other.
• Tighten the screws .
Step 2: Insert Upper Electrode
• Turn the thumbscrew on the right side of the electrode holder counterclockwise to open the gap
enough for an electrode to slide in between the two clamp plates.
• Insert an 1/8" diameter electrode between the clamp plates and hold at desired height.
• Turn the thumbscrew clockwise to tighten the electrode in place (use pliers to ensure it is tight if neces-
sary).
Step 3: Attach Negative Weld Cable to Lower Electrode Assembly
• Remove the black weld cable from the Isolation block.
• Attach the cable to the back of the lower electrode holder (optional accessory/purchased separately)
Make sure the screw is tight.
Step 4: Attach and Align Lower Electrode Holder Assembly
• Remove the plastic cover from the front of the base (the plastic screws should pop out with a little
applied tension).
