MFA-1 Size 6 Oxy-Acetylene Rosebud Heating Tip

Victor Style MFA-1 Size 6 Heating Tip Overview

Maximize your oxy-fuel torch's potential with the Victor Style MFA-1 Size 6 Heating Tip. This premium aftermarket consumable is designed to replicate the performance of the original Victor MFA-1 series, providing professional welders with a cost-effective solution for heating applications. The tip is specifically calibrated for use with Oxy-Acetylene gas, utilizing the high combustion temperature of acetylene to deliver rapid localized heating. It is a critical accessory for any welder using a medium-duty torch handle, such as the Victor 100 series or compatible equivalents.

Technical Specifications and Design

The MFA-1 #6 features a multi-flame head, commonly referred to as a "rosebud," which distributes heat over a wider area than standard welding tips. This design prevents hot spots and ensures uniform heating, which is essential for processes like annealing, normalizing, and flame straightening. The tip is manufactured from a single piece of copper alloy, ensuring excellent thermal conductivity and resistance to deformation under high heat. The connection end is precision-threaded to mate perfectly with medium-duty mixers and handles, utilizing double O-rings to prevent gas bypass and backfires.

Operational Parameters

For optimal performance, this size 6 tip requires specific pressure settings. While settings can vary based on hose length and regulator type, typical operating pressures for a size 6 MFA-1 involve an oxygen pressure range of approximately 8-12 PSIG and an acetylene pressure range of 6-10 PSIG. It is imperative to never exceed 15 PSIG for acetylene. This tip is ideal for heating materials up to medium thickness, making it a versatile choice for automotive repair, HVAC installation, and general metal fabrication. It allows operators to quickly bring metal to the plastic state for bending or to the correct temperature for silver brazing large copper pipes.

Why Choose This Replacement Tip?

Choosing this Victor Style replacement part ensures you get the functionality of a top-tier brand without the premium price tag. It integrates seamlessly into existing Victor-style medium-duty setups, requiring no adapters or special tools. Whether you are removing seized nuts, preheating a casting, or shrinking metal, the MFA-1 Size 6 provides the consistent, high-intensity flame profile required for professional results. Ensure your shop is equipped with this versatile heating head to handle thermal processing tasks with efficiency and precision.
