CS1645 - Victor CutSkill Airco Style 164-5 Acetylene Tip, 4-Inch Cut

Heavy-Duty Cutting Power for Airco Torches

When you are staring down a 4-inch thick slab of steel, you need a tip that can deliver the heat and the oxygen stream to punch through it cleanly. The Victor CS1645 is your go-to replacement for the classic Airco 164-5 acetylene tip. Designed for welders and fabricators who rely on Airco-style torches, this tip brings the legendary Victor CutSkill quality to your existing equipment setup. It is built to handle the heat, literally, with a heavy preheat flame pattern that helps you start cuts faster, even on cold mornings or when dealing with rusty, dirty plate.

Performance You Can Trust
This size 5 tip is a beast for heavy fabrication and demolition work. It is rated to cut through steel up to 4 inches thick, making it ideal for structural steel work, scrap yards, and heavy equipment repair. The heavy preheat design ensures that you maintain the puddle even when moving at speeds of 7 to 10 inches per minute. You won't have to fight to keep the cut going; just set your oxygen to 60 psi and your acetylene to a low 4 psi, and let the tip do the work.

Seamless Compatibility
Don't worry about fitment issues. The CS1645 is machined to fit perfectly into standard Airco-style cutting attachments and torches. It seats tightly to prevent leaks and flashbacks, giving you peace of mind while you work. Whether you are in the shop or out in the field, having a reliable size 5 tip in your kit ensures you are ready for the big jobs that smaller tips just can't handle. Upgrade your consumables with Victor's proven engineering and keep your cuts clean and efficient.
