If you are looking for piercing power the MAG3836™ is a favorite among repair personnel and scrappers alike. It will cut, gouge, wash, shape and more. It is useful for piercing long equipment pins. A 24” pin can be pierced and shrunk for removal in as little as 10 minutes (2 cutting tubes). Consider using a tube extender that comes in both 18" and 36" lengths to gain additional distance from the burn zone. This is particularly useful during challenging piercing situations.
Convenient flame tube extender for additional reach comes in both 18" or 36" lengths.
Magnum's particle stream provides 10,000 degrees of cutting power to melt through anything, including stainless steel, cast iron, manganese, hard-facing, and even rocks. No preheating means a small HAZ (heat affected zone) This frequently translates into less problems with post metal fatigue. If you have ever cut a plate, re-welded it and had the plate crack next to the welds, you have experienced heat fatigue. This is why it is recommended that welds be stress relieved after plate cutting so as to relieve the internal pressures that have built up because of softening the surrounding metal with oxyacetylene gas. This is not a problem with our flame tubes which burn so hot and cut so fast there is actually less heat introduced into the material. Amazing but true.
Cutting and piercing stainless using new technology. Faster and far greater control. See video for more examples. Ten-thousand degrees can easily melt through stainless as the frame above shows. Merely press the tube against the steel and push. The flame does the rest. This process is quite handy for piercing through equipment pins.
Our deluxe ignition is a power booster with convenient prongs for igniting flame cutting tubes. The multi-purpose booster provides many functions. There is a handy recharger, battery status gauge and optional jumper cables to start your car, truck or welder. The charging socket also powers laptops, cell phones and work lights. The ignition comes with different battery configurations from extreme portability to rugged all day work duration. Click on the picture for additional information.
When piercing through thick materials like equipment pins, rocks or fire brick, a flame tube using an extender provides some distance from the operator to the burn zone. This distance keeps the blowback away from the operator and makes the pierce far more convenient. Horizontal pierces allow the magma to escape through the back side of the hole using gravity. A slow steady piece ensures a straight hole which is mandatory if piercing heavy equipment pins where collateral damage must be prevented. Tube extenders also allow for line of sight making it easier to keep the tube in the center of the hole.
For almost 14 years Magnum has been providing cutting rods that cut longer with less sparks than a traditional cutting rods. The tubes have been deployed in every conceivable industrial setting. Our cutting tubes are also used in emergency rescue and tactical situations for breaching contingencies.
Flame tubes are unique in that they cannot function separate from the system. Steel tubes are straightened and micro-coated to resist corrosion. They are subsequently filled with solid fuel spokes that can only combust in the presence of pure oxygen and an initial catalytic spark. Thus, flame tubes are quite safe and reliable.
The outer tube and inner fuel are configured so that the inner fuel conforms to the inside of the tube in a corolla fashion so that a carburetor hole remains. Crimps hold the solid fuel spokes in position. The overall result provides a consistent burn for smooth cutting, gouging and piercing.
Flame tubes fit into the torch head against a rubber washer. They are held in place by virtue of a brass collet. The arrangement is designed so as to prevent head leaks. Oxygen flows through the tube. A spark ignites the tip of the tube and inner fuel. Once ignited, no additional spark is required. The tube will continue to burn so long as oxygen pressure of ten pounds or more is present.
A 2" recess in the rear of the flame tube ensures the flame will extinguish as it nears the torch head. This safety recess prevents flashbacks. Flame tubes are ideal for repair, maintenance and situations where speed of cutting is important.
An example of a .375" cutting tube using oxygen as the sole gas to easily cut through 2" of plate. See the video for more examples. It takes a mere 12 volt spark to ignite a flame tube. Once ignited, the flame tubes burn without additional spark so long as positive oxygen flow is present. Flame tubes can burn with as little pressure as 15 pounds of oxygen for sheet metal. When oxygen pressure is increased, the flame length is also increased. High oxygen pressure can burn a hole through solid rock. When rocks get stuck in crushers, this is the handy tool to pierce and fragment such boulders to get production going again.
A two inch safety recess is built into the rear of the flame cutting tube so as to provide a buffer against burning into the torch head. Three crimps on the exterior of the flame cutting tube ensure the solid spoke fuel retains its radial design. Magnum has experimented over the years to ensure the critical crimps provide reliable performance on land as well as in underwater cutting settings.
The hottest oxyacetylene flame is limited to a temperature of 5,600 degrees. Although a well adjusted flame has been used for cutting for decades, anyone accustomed to using a gas flame realizes the temperature has limits. Not only are there preheating delays, the preheating also encourages the surrounding metal to become soft. Moreover, an oxyacetylene flame cannot burn through laminates, since the flame will stop after the first layer. Our flame cutting tubes melt through multiple layers as of cutting through one. Finally, the low heat prevents burning through such hard metals as stainless, cast iron, manganese, T11 plate, hard-facing, copper, zinc, aluminum and more. Since flame cutting tubes burn without acetylene, dangers associated with combustible gas are eliminated.
Our cutting tubes will fit into most brand torches using our standard collet, including Broco®, Arcair® and Oxylance®. Some manufacturers refer to our tubes as cutting rods.
