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. A standard electrode should be
replaced when the depth exceeds .044 inch (1.1 mm). The SilverPlus electrode may be replaced when the pit
depth exceeds approximately double the recommended depth of a standard electrode.
• Wipe the current ring in the torch with a clean paper towel or cotton swab (see Figure 4-7).
• Refer to the
Cut Charts
to choose the correct consumables for your cutting needs.
2. Replace consumable parts. Refer to
Changing Consumable Parts
later in this section for detailed information on
replacing consumables.
3. Ensure that the torch is perpendicular to the material. Refer to
Section 3
