SLICE EXOTHERMIC CUTTING EQUIPMENT

SECTION 6:
OPERATION
SLICE Exothermic Cutting uses heat from a chemical reaction between a consumable steel rod and
oxygen flowing through the rod. Test data show that little or no oxygen remains. The oxygen not used in
the reaction blows the molten material out of the cut area. This action creates the kerf that allows cut
progression.
6.01 Cutting without Power
Cutting without power uses the heat reaction from the rod and the oxygen to cut. To initiate this type of
cutting, ignite the rod from a spark supplied by a 12-volt battery or by a welding power source capable
of delivering a 100-amp surge. Once this spark has ignited the rod, the electrical path is broken and the
heat of the reaction melts the material and cuts it.

Figure 4: Cutting without Power
Cutting without power can be done in remote areas. Support equipment and bulky power sources are
not needed.
1. Connect the torch to either terminal of a 12-volt battery or constant-current welding power
source, then connect the striker or a strike plate to the other terminal. If using a welding
power source, set output level for 100 amps.
2. Turn on the oxygen supply and adjust the regulator to the proper working pressure. Insert the
cutting rod into the collet and tighten the Collet Nut.
3. Tap the cutting rod on a hard, ungrounded surface to seat the rod in the torch.
4. Depress the torch oxygen valve lever and check for oxygen leaks around the Collet Nut.
NOTE!
If oxygen is leaking, repeat the procedure until no oxygen is leaking.
