Victor’s ST900FC is a workhorse torch handle for oxy-fuel cutting and heating. It’s the current flow-control version of the classic 100-series design, built for reliability in fabrication shops, maintenance departments, and field repair work. This guide covers specs, performance details, and selection notes for welders and fabricators.
Key Takeaways
- Heavy-duty Victor 0381-1621 torch assembly
- Part of Victor’s ST900FC line with built-in Flash-Guard® check valves

What the ST900FC Solves
1. Flashback protection
Built-in Flash-Guard® check valves help meet OSHA/ANSI recommendations for flashback prevention.
2. Consistent flow control
High-flow needle valves allow smoother oxygen/fuel metering than older economy torch bodies.
3. Shop-grade durability
Brass body and metal valve assemblies handle frequent usage, heat cycling, and impacts better than light-duty consumer torches.
