INSTRUCTION MANUAL

DANGER

EXTREMELY FLAMMABLE GASES USED WITH TORCH FIRE/EXPLOSION HAZARD CARBON MONOXIDE HAZARD

This oxygen brazing and cutting torch is unlike most hand held torches. It is designed to be used simultaneously with an oxygen cylinder and a Pro Gas or propane cylinder.The use of an oxygen cylinder results in the torch flame burning at much higher temperatures as it would without an oxygen cylinder. Do not use this torch until you become thoroughly familiar with its proper use and potential hazards. In particular, you must not attempt to ignite the torch while oxygen is flowing to the torch. Further, when turning the torch offALWAYSTURN OFF THEOXYGENBEFORE TURNING OFF THE FUEL GAS. Turning off the fuel gas while oxygen is still flowing could result in a flash back and an explosion.

Read and follow the instructions and warnings in this manual. Familiarize yourself with the torch before lighting and using. Review instructions and warnings periodically to maintain awareness. Do not try to operate before reading instructions and without being thoroughly familiar with this torch's use and potential hazards.

Failure to comply with these instructions and warnings may result in damage to property, serious personal injury, or death.

WARNING

• ● While the Oxygen-Pro GasTorchis not a commercial oxygen torch, it produces flame temperatures up to5300oF.This is much hotter than the flame of a standard propane torch. These extremely high temperatures can cause serious personal injury or damage to the metal you are working on if not handled carefully and correctly.
  • ● Never point the torch toward the cylinders or let the flame deflect to heat the cylinder in any manner.
• ● Do not permit grease or oil to be placed on or come in contact with any portion of the torch, hoses or cylinders, particularly the oxygencylinder, oxygen connection, oxygen regulator or oxygen hose as oxygen can cause the grease or oil to burn in an uncontrolled manner.
• ● Keep torch out of reach of children and anyone who has not read instructions. Do not point torch towards face, other persons or flammable objects. Never attempt to use torch as a cigarette lighter.
  • ● Disconnect cylinders when not in use.
  • ● Never attempt to modify the torch construction and never use unapproved accessories or fuels.
  • ● Treat the torch as you would any fine tool or instrument. Do not drop, throw, or otherwise abuse.
  • ● Do not use a leaking, damaged or malfunctioning torch.
  • ● Always wear safety glasses, protective gloves and use proper tools to handle hot work.
• ● Radiant energy can harm youreyes.Wear glasses having an appropriate lens shade number for the torch operation being done; brazing and light cutting, medium cutting and light welding, heavy cutting and medium/heavy welding.
• ● Work only in well-ventilated areas. Avoid the fumes from fluxes, lead-based paint, and all metal heating operations. Be careful to avoid fumes from cadmium plating and galvanized metal-remove these coatings in the area to be heated by filing or sanding prior to heating.
  • ● Never use torch to strip lead paint.
• ● Be careful when using the torch outdoors on sunny or windy days. Bright light makes it difficult to see the torch's flame. Wind may carry the torch's heat back towards you or other areas not intended to be heated. Windy conditions may also cause sparks to be blown into other areas with combustible materials.
• ● Heating a surface may cause heat to be conducted to adjoining surfaces that may be combustible or become pressurized when heated. Always check to make sure no unintended parts or materials are being heated,
  • ● Be aware that the tip of the torch can get extremely hot during use.Takeprecautions to protect yourself and others from accidental burns.
• ● Never use the torch on or near combustibles. Be careful around motor vehicles or any gasoline-fired products and beware of hidden fuel lines and tanks.
• ● Always make certain the torch is placed on a level surface when connected to the fuel cylinder to reduce the risk of accidental tipover.Be sure the torch is not pointed in a direction which could cause nearby objects to ignite when the torch is set down.
  • ● Be careful not to overheat surrounding materials. Use a heat shield when necessary.
  • ● Never leave the torch unattended when lit.
• ● Never attempt to repair or heat a gasoline tank, a chemical drum, an aerosol can, a compressed gas container that held flammable liquid or gas or any other chemical. Heating these is extremely dangerous, especially after theyhavebeen emptied because vapors may still be in thecontainer.
  • ● Alwayshavea fire extinguisher and a bucket of water near the torch and work area.
  • ● This torch consumes oxygen and must only be used in well ventilated areas. Do not use in a confined space.
    • ● Do not operate the torch with a flame that is less than 1/4 inch long because it can overheat the mixing tube and cause flame outage or flashback.
      • ● Do not hold the tip of the torch too close to the work piece. This can cause the flame to go out, cause flashback and weld the tip shut.
      • ● Do not operate the torch if the section of the mixing tube that is directly in front of the torch handle becomes hot. Although the section of the mixing tube immediately behind the tip of the torch can get hot, the section of the mixing tube directly in front of the handle should never get hot. lf this occurs, extinguish the torch immediately by turning OFF the oxygen valve and then the fuel valve. Allow the torch to cool and then check the tip of the torch for blockage. If the tip is unblocked and clean, relight the torch. If the section of the mixing tube that is directly in front of the torch handle still becomes hot, discontinue use of the torch and contact RTM immediately.
      • ● If the flame disappears unexpectedly, immediately turn OFF the oxygen valve and then the fuel valve. Disconnect the oxygen and fuel valves from their cylinders and re-open the valves to bleed the hoses.
      • ● Place the cylinder stand on a stable and level surface. Improper stand position, such as placing the stand on its side, could cause accidental tip over leading to liquid fuel entering the hose and causing an excessively long flame. This is called flare and is very dangerous. It can alsocause the flame to go out.
      • ● DO NOT USE THE TORCH IF THE HOSES SWELL DURING OPERATION. THE HOSES MAY RUPTURE UNEXPECTEDLY AND CAUSEINJURY OR DAMAGE. If the hoses swell, stop using the torch by turning OFF the oxygen valve first and then the fuel valve, Disconnect the valves from the cylinders and then re-open the valves to bleed the hoses. Replace the torch assembly before relighting.
        • ● Always use tools, such as tongs or pliers, to handle brazing/welding rods because they could be hot.
        • ● Beware that certain surfaces can reflect and transfer the heat back to the torch handle causing damage or injuries.
        • ● In cold weather the size of the flame will be smaller.
        • ● Always carry the torch by the handle and make sure the valve side of the cylinders is not tipping downward, which could cause the cylinders to fall Out of the stand.
