Check Torch
1. Remove the consumables from the torch and check for worn or damaged parts.
Always place the
consumables on a clean, dry, oil free surface after removing. Dirty consumables can cause the
torch to malfunction.
• Check the pit depth of the electrode using the electrode gauge assembly. An all copper electrode should
be replaced when the depth exceeds .040 inch (1 mm). A SilverPlus electrode should be replaced when
the pit depth exceeds approximately two times the recommended depth of an all copper electrode.
• Wipe the current ring in the torch with a clean paper towel or Q-tip (see Figure 6-7).
• Refer to the
Cut Charts
in this section to choose the correct consumables for your cutting needs.
2. Replace consumable parts. Refer to the
Changing Consumable Parts
section later in this manual for
detailed information on replacing consumables.
3. Ensure that the torch is squared to the material. Refer to
Section 4
: Installation for the torch alignment
procedure.
