5 . Reinstall the Electrode by pushing it straight into the
torch head until it clicks.
WARNINGS
Refer to the consumables selection charts for the
proper combination of torch parts, including shield
retainers and shield cups.
The use of any consumable parts other than
those specified by the Manufacturer may cause
irreparable damage to the torch head.
6 . Hold the starter cartridge and tip in place on the elec-
trode.
7. Hand tighten the shield cup until it is seated on the
torch head. If resistance is felt when installing the cup,
check the threads before proceeding.
CAUTION
When operating the torch in a normal condition, a
small amount of gas vents through the gap between
the shield cup and torch handle. Do not attempt to
over tighten the shield cup as irreparable damage to
internal components may result.
Consumables Selection
Various front - end torch parts are available for differ-
ent applications.
Use the single - piece Shield Cup for ‘standoff’ cutting
(with the torch tip 1/8" to 1/4" from the workpiece).
This is the preferred method for cutting metal thicker
than 3/16" / 4.8 mm and at current levels above 40
amps. This provides maximum visibility and accessi-
bility.
Use the Shield Cup Body with the Deflector Shield Cap
for extended parts life and improved resistance to re-
flected heat. This combination provides cutting results
similar to the single-piece Shield Cup, as well as easy
change-over to gouging or drag shield cutting.
Use the Shield Cup Body with the Gouging Shield Cap
for excellent gouging performance and enhanced torch
parts life.
The electrode and starter cartridge are the same for all
operations.
Use only Genuine Thermal Dynamics consumables with
this torch. The use of any other consumables may ir-
reparably damage the torch.
