The Ultimate Cutting Tool

The Broco® Underwater Ultrathermic Cutting System is the diving industry’s standard for underwater cutting tools. Consisting of the BR-22 Torch, HVR-4400 Regulator and Ultrathermic Cuttings Rods, the Broco® Underwater system provides the fastest, most efficient and cost effective means of completing underwater tasks involving cutting, piercing or gouging.

The Ultrathermic Cutting produces a temperature in excess of 10,000° F; hot enough to quickly cut or melt through almost anything including cast iron, stainless steel, brass, other ferrous and non-ferrous metals and concrete. 10,000° F means it cuts quickly and efficiently, producing more cut per inch of rod than any other on the market. The Ultrathermic Cutting Rod will cut through marine growth, rust and mill scale eliminating the need for pre-cleaning. This translates to lower operating costs and red„ced bottom time.

Safe and Easy to Use
While other equipment may require as much as 500 amps to cut, the Broco® Underwater Ultrathermic Cutting System uses only oxygen and maximum of 150 amps. In fact, the Ultrathermic Cutting Rod readily ignites from a spark generated by a 12 or 24 volt auto or marine battery. The rod will continue to burn w/ electrical current removed until the flow of oxygen is stopped or the rod is consumed. The need for expensive support equipment is reduced while a safer diving environment is maintained. The recommended oxygen working pressure of 90 psi over bottom economizes oxygen consumption.

Made For Divers, By Divers
Cut sheet pile, remove tubular supports or trim damaged hull plates. Slag-free gouging means easy weld removal and edge preparation. ANU (Approved for Navy Use) designated and featured in the US Navy’s “Underwater Cutting and Welding” manual, the Broco® Underwater Ultrathermic Cutting System is used by navies around the world.

Broco® BR-22 Cutting Torch

BR-22 Parts Breakdown

The BR-22 Cutting Torch is ergonomically designed for diver comfort and to reduce forearm fatigue. The torch is constructed from durable high-impact and corrosion resistant materials. All the metal parts are brass. The non-conductive flexible coupler joining the oxygen control valve to the torch head is a key safety feature, unique in design and found only in Broco’s torch. All connections are threaded for ease of maintenance (spare parts kits are available). The solid brass flash arrestor w/ internal filter screen protects the diver and torch without restricting oxygen flow. The large collet nut is knurled to assure the diver of a solid grasp. Acme threads prevent binding from mud or other debris, insuring quick, reliable rod insertion and retention. Interchangeable collets accommodate 3/8", 5/16" or ¼” diameter cutting rods and allow the BR-22 to be used as a welding electrode holder. The BR-22 Cutting Torch has been built to deliver years of trouble free performance at minimum cost. The ultimate value.

HVR-4400 Oxygen Regulator

HVR-4400 Parts Breakdown

The 2-stage Broco® Underwater HVR-4400 Regulator (used w/ 3/8” ID oxygen hose) delivers the high volume of oxygen required to optimize Ultrathermic cutting performance. UL listed, the HVR-4400 has been designed and manufactured for ruggedness, ease of operation and maximum efficiency.

For underwater burning, where speed and accuracy are required

• Constant volume from a single source. Working from a pocket reservoir for smooth flow rate.
• Stainless dephragm in the safety stage reduces cylinder pressure by 90%. Large second stage diaphragm, allows for sensitive adjustments and accurate delivery.
• Inlet filter keeps out foreign matter
• Vented and equipped w/ pressure relief valve between stages.
• UL approved

Broco Underwater Ultrathermic Cutting Rods

Burning in excess of 10,000° F at the tip, Broco® Underwater Ultrathermic Cutting Rods cut or melt virtually any known material. Broco’s patented rod design features alloy core wires retained by a series of circular crimps. Recessing these internal wires on the torch end of the rod prevents burnback into the torch, making Broco® Underwater Ultrathermic Cutting Rods the safest on the market. Ultrathermic Cutting Rods can be bent 90° or more to access hard to reach places, without restricting oxygen flow or causing the insulation to split or flake off. Although they can be used w/ a maximum of 150 amps, Ultrathermic Cutting Rods have no electrical requirement. Once ignited, they will continue to burn as long as oxygen is supplied or until the rod is consumed. Broco® Underwater Ultrathermic Cutting Rods are available in ¼” and 3/8” diameters to suit the diver’s job requirements. Standard length is 18”. For heavy cutting jobs, 36” long Ultrathermic Cutting Rods allow more burn time between rod changes. Cut, pierce or gouge underwater, safer, faster and w/ lower operating costs by using Broco® Underwater Ultrathermic Cutting Rods.
