Consumable selection
Standard cutting (0°)
Most of the consumables on the following pages are designed for standard (straight) cutting, when the torch is
perpendicular to the workpiece.
Bevel cutting (0° to 45°)
Consumables for 130 amp and 260 amp bevel cutting are specifically designed for bevel cutting. 400 amp
consumables can be used for standard cutting and bevel cutting, but bevel-specific, 400 amp cut charts are provided
for convenience.
Marking
Any of the consumable sets can also be used for marking with argon or nitrogen. Marking parameters are shown at the
bottom of each cut chart. The quality of the marks will vary depending on the marking process, cut process, material
type, material thickness, and material surface finish. For best mark quality, use the argon marking process settings. For
all marking processes the depth of the mark can be increased by reducing the marking speed, or the depth can be
decreased by increasing the marking speed. Argon marking currents can be increased by up to 30% to increase the
depth of the mark. When marking with an argon process at 25 amps or greater, the process will start with air before
changing to argon, and a thicker, darker mark will be seen at the start of the mark. When using the argon marking
processes, mark and cut individual parts. Marking the entire nest prior to cutting may lead to reduced consumable life.
For better results intersperse cuts and marks. Poor quality marking or burn-through may occur with material less than
1.5 mm (0.06 in. or 16 gauge).
Consumables for mirror-image cutting
See the Parts List section in this manual for part numbers.
SilverPlus electrodes
SilverPlus electrodes provide increased life when the average cut duration is short (< 60 seconds), and cut quality is not
the most critical requirement. SilverPlus electrodes are available for 130 amp, 200 amp, and 260 amp mild steel O
