Praxair StarFlame C Cutting Fuel

StarFlame C cutting fuel cuts cleaner.

Smooth cuts with no gouge marks or rolled edges.

StarFlame C Cutting Fuel is more economical, environmentally friendly, and safer than acetylene and other fuel gases.

  • Quicker start-to-steel ignition point at less cost
  • Faster cutting speed wheather beveling, making sharp turns or cutting intricate patterns
  • Quick, clean piercing
  • Minimal slag and weldback from a cleaner
  • Significantly less smoke and soot
  • Reduced potential for torch backfire

Praxair’s StarFlame C cutting fuel burns hotter than other fuel gases so it cuts quicker.
