ZTIP1063 - Koike 106-3 Propane Cutting Tip, Size 3 (1-1/2" Cut)

Precision Propane Cutting with Koike 106 Series

The Koike 106-3 Standard Propane Cutting Tip is a high-performance consumable designed for industrial oxy-fuel cutting applications requiring precision and efficiency. Engineered specifically for use with Propane (LPG) gas, this Size 3 tip is rated for cutting steel plates with a thickness of 1-1/2 inches (approx. 38mm). The 106 series utilizes a 2-piece design, featuring a brass outer shell and a splined brass inner member, which optimizes the pre-heat flame characteristics for alternative fuels like propane, ensuring a stable and hot pre-heat even in demanding conditions.

Engineered for Quality and Safety

Koike employs rigorous manufacturing criteria to ensure that every 106-3 tip delivers a superior cutting surface. The tip geometry is designed to produce a consistently even cut face with a minimal kerf width, significantly reducing material waste. Operators will observe a marked reduction in top and bottom slag, as well as minimal upper edge melting, which reduces the need for secondary grinding or machining operations. Safety is paramount in the design of the 100 series tips; they are engineered to minimize the risk of damaging flashbacks and backfires, protecting both the operator and the torch equipment.

Operational Specifications

To achieve optimal results, the Koike 106-3 requires specific pressure settings. It operates best with a cutting oxygen pressure of 45 PSIG and a fuel gas pressure of approximately 3.6 PSIG. These parameters ensure the high-velocity oxygen stream maintains its integrity throughout the cut, delivering deep penetration and a clean drop cut. Each tip undergoes strict quality assurance inspections, including firing and cycling tests, to verify that the flow rates and flame structure meet Koike's high standards before reaching the end-user.

Compatibility and Durability

This tip is compatible with Koike 100 series torches and other industry-standard equipment designed for 106-style tips. The chrome-plated finish (where applicable) or high-quality brass construction ensures resistance to heat and spatter adhesion, prolonging the service life of the consumable. Whether used in automated cutting machines or manual hand torches, the 106-3 provides the reliability and consistency required for professional metal fabrication.
