WARNING
Before operating this system, you must read the Safety section thoroughly! Turn main disconnect
switch to the power supply OFF before proceeding with the following steps.
Noise Levels
Acceptable noise levels as defined by national or local codes may be exceeded by this plasma system. Always
wear proper ear protection when cutting or gouging with the plasma system. See also Noise Protection in the
Safety section of this manual.
Daily Startup
Prior to startup, ensure that your cutting environment and that your clothing meet the safety requirements outlined
in the Safety section of this manual.
Note: For operation with argon-hydrogen manifold, see the appendix section of this manual.
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 for the torch alignment procedure.
