Setting up a Cut
Use the following procedure to make a cut with the SR-45i.
1.
Using the charts in this section, determine the proper torch parts and cutting
conditions for the material being cut.
2.
Apply a small amount of o-ring lubricant PN 716008 to the o-ring PN 770072
on the torch body.

3.
Place the advanceable electrode PN 770015 or non-advanceable electrode PN
770017 into the swirl ring PN 770012 by inserting the small end of the
electrode into the large opening of the swirl ring. The large diameter of the
electrode should bottom-out and fit snugly into the swirl ring.
4.
Place the appropriate nozzle onto the small end of the swirl ring. Use the
tapered metal cutting nozzle PN 770104 for cutting gauge material through
1/8”, or use the flat metal cutting nozzle PN 770000 for cutting material over
1/8” thick. Use the insulation cutting nozzle PN 770030 for cutting insulating
material. Note that the insulation cutting nozzle has a groove machined in the
side so it can be distinguished from the flat metal cutting nozzle.

5.
Place the electrode/swirl ring/nozzle assembly into the retaining cap PN
770098 and make sure the nozzle flange is seated in the retaining cap recess.
6.
Thread the retaining cap onto the torch and hand tighten FIRMLY. It is very
important that all parts are seated tightly to prevent the torch from arcing
internally.
