StarFlame C

StarFlame™ C Cutting Fuel burns hotter than other fuel gases so it cuts quicker. StarFlame C cutting fuel is more economical, environmentally friendly and safer than acetylene and other fuel gases with:

Features

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

StarFlame C Cutting Fuel Cuts Cleaner

Why StarFlame C should be your fuel gas of choice.

When compared to acetylene, StarFlame C cutting fuel is considered a “forgiving” fuel gas because good results can be achieved even when the heating or cutting tip is too close to the workpiece or when distance opens up one to two inches during cutting. Maintaining an exact distance from the workpiece is not critical, which makes StarFlame C cutting fuel an excellent choice for hand-torch cutting.
