Not Cutting Through
A partial or no cut usually traces back to the nozzle, focus height, assist-gas pressure, or pierce settings for the material.
- Inspect the nozzle and protective lens for damage or debris.
- Confirm focus height and nozzle standoff.
- Verify assist-gas pressure and pierce timing for the thickness.

Edge / Cut Quality
Dross, burr, or a rough edge points to the gas, feed rate, power, or a worn protective lens.
- Match gas type and pressure to the metal.
- Tune feed rate and power together.
- Replace the protective lens if it is fogged or spotted.

Assist Gas & Pierce
Gas choice and pierce timing set the cut. Oxygen, nitrogen, or air each suit different metals and thicknesses.
- Set oxygen, nitrogen, or air to the metal type.
- Confirm pressure at the head, not just the regulator.
- Tune pierce timing to the material thickness.

Common questions
FC Series FAQs.
Which manual covers my FC cutter?
FC manuals are model-specific because platforms differ. Open your exact model in the list below for its operator’s manual and setup references, or download from the Boss resources library.
What assist gas should I use?
As a general rule, oxygen suits mild steel, nitrogen suits stainless and aluminum for clean edges, and compressed air is an economical option on thinner material. Confirm the right gas and pressure for your thickness in the fiber power guide.
Why isn’t my FC cutting all the way through?
Check the nozzle and protective lens first, then focus height, assist-gas pressure at the head, and pierce timing for the thickness. Worn consumables are the most common cause.
