The Bernzomatic 0X 2550 Mini torch uses a tank of MAPP gas and a tank of oxygen, which sets it apart from common Bernzomatic propane torches. The torch comes in a kit, which includes a burner wand, hose, oxygen regulator, fuel gas valve cylinder stand, MG9 454gr. MAPP Gas cylinder, a OX9 1.1 cubic foot oxygen cylinder, spark lighter and 5 brazing/welding rods. The Bernzomatic 0X 2550 Mini torch is sold as a welding, brazing and cutting torch, but the cutting feature is limited to unhardened screws and small bolts. Setting up the Bernzomatic 0X 2550 Mini torch only takes a few minutes, and using it is similar to using an oxyacetylene torch rig.
- Skill level:
Attach the gas and oxygen cylinders to the hoses by screwing the oxygen cylinder onto the brass connector with a large plastic knob on top of it, and the MAPP gas cylinder onto the brass connector with the plastic knob on the side. Set the cylinders in the cylinder stand.
Open the gas valve by turning it counterclockwise, between 1/8 and 1/4-turn. Hold the cup of the spark lighter over the end of the burner wand and squeeze the handle. Squeezing the handle drags a Flint over a knurled piece of steel inside the cup, causing a spark that ignites the gas.
Open the gas valve until the flame no longer smokes. The resulting flame should be approximately 8-inches long. Open the oxygen valve until the feather around the inside of the flame is gone. The torch is now ready to perform any welding or brazing operations. Open the oxygen valve further without extinguishing the flame, until there is a hot enough flame for cutting tasks.
Shut the torch off by first closing the oxygen valve, then the MAPP gas valve. Disconnect the oxygen and gas cylinders from the hoses.
Tips and warnings
- Always wear protective clothing, gloves and face protection when operating welding or cutting torches.
