GPN-4 - Flame Tech GPN-4 Propane Cutting Tip Size 4 for Victor 300 Series

Reliable Cuts with the Flame Tech GPN-4 Replacement Tip

Upgrade your cutting setup with the Flame Tech GPN-4, a high-quality replacement cutting tip designed for use with propane and natural gas. Built to compatible specifications for Victor 300 Series torch handles, this Size 4 tip is the go-to choice for welders needing to slice through steel approximately 3 inches thick. By utilizing propane or natural gas, shops can significantly reduce fuel costs compared to acetylene, and the GPN-4 is the specialized tool required to make that transition effective and efficient.

The GPN-4 utilizes a two-piece construction method, which is the industry standard for alternative fuel tips. This design separates the preheat splines from the outer shell, creating a deep recess that protects the flame front and allows the gas to burn correctly. Propane burns at a different velocity than acetylene, and using a standard one-piece tip would result in flame instability and poor cut quality. The Flame Tech GPN-4 solves this by anchoring the flame effectively, providing the intense preheat needed to bring steel to its ignition temperature quickly.

Durability is built into every Flame Tech tip. The outer shell is crafted from high-grade copper to resist heat deformation and spatter adhesion, while the inner insert is machined from brass for precise gas distribution. This combination ensures that the tip holds up under the rigors of daily use in harsh shop or field environments. Furthermore, the two-piece design makes cleaning straightforward; simply separate the parts to clear out carbon buildup or debris, ensuring your tip performs like new for longer.

Whether you are cutting scrap, fabricating heavy machinery parts, or performing on-site repairs, the GPN-4 delivers consistent results. It offers a smooth kerf and excellent slag control, reducing the amount of post-cut grinding required. For welders who demand value without compromising on performance, the Flame Tech GPN-4 is an excellent alternative to OEM consumables, delivering professional-grade cuts at a competitive price point.
