Victor ST900FC Heavy-Duty Straight Cutting Torch – 21" Length, 90° Head

Heavy-duty straight cutting torch with built-in flashback arrestors and reverse-flow check valves.
The Victor ST900FC Straight Cutting Torch is designed for heavy- and medium-duty oxy-fuel cutting applications. This configuration features a 21" (53cm) overall length, 90° head, top-rear cutting oxygen lever, and Series 1 cutting tip compatibility.

The longer 21" torch body provides additional reach for cutting applications while helping the operator maintain distance from the work area. Built-in patented flashback arrestors and reverse-flow check valves provide integrated safety features directly in the torch.

The ST900FC is designed for use with compatible fuel gases operating at 5 PSIG and above.

Key Features

• Heavy-Duty Cutting Torch: Designed for heavy- and medium-duty oxy-fuel cutting applications.
• 21" Straight Torch: 21" (53cm) overall length provides additional reach for larger workpieces and demanding cutting applications.
• 90° Head: Standard 90-degree cutting head configuration.
• Built-In Flashback Arrestors: Patented flashback arrestors are integrated into the torch.
• Reverse-Flow Check Valves: Built-in check valves help prevent reverse gas flow.
• Series 1 Cutting Tips: Compatible with a wide range of Victor Series 1 cutting tips.
• 1/8" to 5" Cutting Capacity: Wide cutting range when equipped with the appropriate tip and operating setup.
• Multiple Fuel Gas Capability: Designed for compatible fuel gases operating at 5 PSIG and above.
• Top-Rear Lever: Cutting oxygen lever is positioned at the top rear of the torch.
• 9/16"-18 Hose Connections: Standard hose connection configuration.

21" Extended-Reach Design

The 21" (53cm) overall length provides additional reach compared with shorter cutting torches. This can be useful when working on larger plate, structural components, and applications where additional distance between the operator and cutting area is beneficial.

The straight-body design and 90° head provide a familiar cutting configuration while maintaining access to the top-rear cutting oxygen lever.

1/8" to 5" Cutting Capacity

The ST900FC provides a cutting capacity from 1/8" (3.25mm) through 5" (127mm) when equipped with the appropriate Series 1 cutting tip and operated with the proper gas pressures and flow rates.

Always select the cutting tip and operating parameters appropriate for the material thickness, fuel gas, and cutting application.

Built-In Safety Features

The ST900FC incorporates patented flashback arrestors and reverse-flow check valves directly into the torch.

The flashback arrestors are designed to help prevent a flame from traveling upstream through the torch, while the reverse-flow check valves help prevent gases from flowing backward into the opposite gas line.
