CSMC121 - Victor CutSkill MC12-1 Smith Style Acetylene Cutting Tip Size 1

Technical Overview of the Victor CutSkill CSMC121

The Victor CutSkill CSMC121 is a precision-manufactured replacement cutting tip designed to be fully compatible with Smith medium-duty oxy-acetylene cutting equipment. Engineered to replicate the performance specifications of the Smith MC12-1, this tip is designated as a Size 1 nozzle, optimized for cutting mild steel thicknesses ranging from approximately 5/8 inch to 3/4 inch (15mm to 19mm). It utilizes a standard 1-piece copper alloy construction which ensures efficient heat transfer and durability under thermal cycling.

This tip belongs to the MC12 series, specifically calibrated for Acetylene gas. It features a medium preheat pattern, making it suitable for general fabrication, maintenance, and repair applications where surface conditions may vary. The gas flow characteristics are designed to operate efficiently within standard pressure ranges: Oxygen at 30-35 PSIG and Acetylene at 5-10 PSIG. Operators should ensure their regulators are set within these parameters to maintain a neutral flame and prevent backfires or sustained backfire conditions.

The CSMC121 fits standard Smith medium-duty cutting attachments (such as the MC505 or MC509) and torch handles commonly found in the industry. The seating surfaces are machined to tight tolerances to ensure a leak-proof seal with the torch head, critical for safety and performance in oxy-fuel processes. As part of the Victor CutSkill line, this product bridges the gap between economical pricing and professional-grade reliability, suitable for industrial MRO environments.
