430-420159 - Hypertherm 45 Amp Replacement Nozzle Pack

Keep Your Cuts Clean and Your Torch Running

Every welder knows that a plasma cutter is only as good as the consumables inside it. If you are running a Hypertherm Powermax machine at 45 amps, this 5-pack of replacement nozzles is exactly what you need to keep your production line moving. The nozzle is the business end of your torch—it squeezes the plasma arc into a tight, hot stream that slices through metal like butter. Over time, that tiny hole in the tip gets blown out, oval-shaped, or covered in spatter. When that happens, your nice sharp cuts turn into sloppy, dross-filled messes that take forever to grind clean. Swapping in a fresh Hypertherm 45A nozzle brings your machine back to factory-fresh performance instantly.

Why stick with genuine Hypertherm parts? It comes down to frustration-free working. Cheap knock-off nozzles often don't thread right, burn out twice as fast, or cause the arc to wander, making it impossible to follow a line. These OEM nozzles are built with heavy-duty copper that handles the heat of 45-amp cutting without melting down halfway through a job. They are designed to work perfectly with your Duramax torch, ensuring the air flows exactly where it needs to go to cool the stack and blow the molten metal out of the kerf. Whether you are cutting gauge sheet metal for HVAC ducting, fabricating brackets from 1/4-inch plate, or doing artistic scrollwork, these nozzles give you the control you need.

This pack includes five nozzles, which is the perfect amount for a busy shop. There is nothing worse than being in the middle of a rush job on a Friday afternoon and realizing your last tip is blown. With a 5-pack in your toolbox, you are covered. You can change them out the second you notice the arc turning green or the cut quality dropping, rather than trying to push a bad tip too far and ruining your workpiece. These nozzles are compatible with standard drag-cutting shields and mechanized shields, making them versatile for both hand cutting and table operations.

Installation is simple: unscrew the retaining cap, swap the worn nozzle, check your electrode, and screw it back together. No tools needed, just hand-tight. By keeping fresh nozzles on hand, you protect your torch head from damage and ensure that every trigger pull results in a clean, instant start. Don't let a ten-dollar part ruin a thousand-dollar project—stick with genuine Hypertherm consumables.
