3. Choose a matching set of Collet and
Collet Holder, either 1/16" (4a & 5a)
or 3/32" (4b & 5b), depending on the
rod to be used. Insert the Collet, nar-
rower end first, into the Collet Holder,
and then thread the Collet Holder

rod (the correct diameter for the Col-
let used) into Collet. Tighten Collet
Holder in place.
5. Attach desired Ceramic Nozzle (3a or
3b) onto Collet Holder. do not over-
tighten. Ceramic Nozzles of larger
sizes will contain shielding gas in a
larger area, but may require more gas
flow to be effective.
6. Connect the gas hose securely to the
regulator on the argon bottle. Set the
argon regulator to 18-22 PSI. Fol-
low the gas cylinder manufacturer's
instructions for set-up and use.
