6 – Machine Torch Setup
FineCut shielded with ohmic consumables
Install the machine torch consumables
To operate the machine torch, a complete set of consumable parts must be installed: shield, retaining cap, nozzle,
electrode, and swirl ring.
With the power switch in the OFF (O) position, install the machine torch consumables in a manner similar to the hand
torch consumables. See Hand Torch Setup on page 51.
Aligning the torch
Mount the machine torch perpendicular to the workpiece in order to get a vertical cut. Use a square to align the torch at
right angles to the workpiece.

Position the mounting bracket as low on the torch as possible to minimize vibration at the
tip of the torch.
WARNING!
INSTANT-ON TORCHES
PLASMA ARC CAN CAUSE INJURY AND BURNS
The plasma arc comes on immediately when the torch trigger is activated. Make sure the
power is OFF before changing consumables.
