Get the Job Done with Purox Reliability

When you are staring down a thick plate of steel, you need a cutting tip that won't let you down. The ESAB Purox 4202 Series Size 4 Acetylene Cutting Tip is built for the welder who needs to cut through 2 to 4 inches of metal without constant adjustments or flame issues. Whether you are scrapping old machinery, prepping structural beams, or performing field repairs, this tip delivers the heat and the punch you need to make clean, fast severs. It is a workhorse nozzle designed to keep your production line moving and your downtime low.

The Size 4 tip is particularly favored for its versatility. While it excels at straight cuts, its medium preheat feature really shines when you need to prep edges. The six preheat holes provide a stable ring of fire that keeps the steel at ignition temperature, even when you are angling the torch for a bevel. This means you can transition from square cuts to weld-prep bevels without changing out your consumables. The one-piece copper design is tough as nails, resisting damage from spatter and accidental bumps better than more fragile multi-piece tips. Plus, being a single piece means fewer seating surfaces to leak or get damaged.

Setting up is straightforward. Dial your oxygen to around 40-75 PSIG and your acetylene to a safe 6-10 PSIG, and you are ready to rip. The tip produces a consistent kerf, meaning you aren't blowing away more metal than necessary, and the cut face remains relatively smooth, saving you time on the grinder later. It is designed to fit standard Purox style torches, so if you are already running a Purox setup, this drops right in. It’s the kind of gear that just works, shift after shift.

Don't settle for generic tips that sputter or clog easily. The ESAB Purox 4202 series is a proven industry standard for a reason. It offers the control you need for precision hand cutting and the durability required for machine applications. If your daily grind involves heavy plate cutting with acetylene, keeping a few of these Size 4 tips in your toolbox is a no-brainer. They deliver the performance professional welders and fabricators demand.
