Step 4 – Install the cartridge

Install the correct cartridge for the cutting that you want to do. Unlock the torch to fire a plasma arc.

SmartSYNC® torches include a switch that lets you lock the torch. This torch-lock switch prevents the torch from firing accidentally, even when the plasma power supply is ON. Cartridges are not preinstalled on new torches.

Use this switch to lock the torch when:

The torch is not in use
You change the Hypertherm® cartridge
You move the plasma power supply or torch while the plasma power supply is ON

Warning

INSTANT-ON TORCHES – PLASMA ARC CAN CAUSE INJURY, BURNS

Ignition of the plasma arc occurs immediately when you pull the torch trigger. Before changing the cartridge, one of the following steps is necessary. Whenever possible, complete the first step.

Set the power switch on the plasma power supply to OFF (O).

Move the torch-lock switch to the yellow lock (X) position. Pull the trigger to make sure that the torch does not fire a plasma arc.

Make sure that the power switch on the plasma power supply stays OFF (O).
Make sure that the torch-lock switch on the torch is set to the yellow lock (X) position.
If this is a new torch, remove the vinyl cap from the torch.
Select the correct Hypertherm cartridge for your cutting or gouging application.
Place the cartridge on the torch, and tighten it 1/4 of a turn to install it.

The Torch Cap Light Emitting Diode (LED) on the front panel comes on when you remove the consumables or set the torch-disable switch to the yellow lock (X) position while the plasma power supply is still ON. The LED extinguishes after you install the consumables and set the torch-disable switch to the green "ready to fire" position.
