Never attempt to repair hoses with tape of any sort.

Having tight connections is extremely important because they will keep both the oxygen and acetylene from leaking. You'll also need to connect the gas supplies, like the oxygen and the acetylene hoses, to the torch. The recommended setting is for the fuel gas regulator to be set at 10 PSIG and the oxygen regulator at 45 PSIG. Open the acetylene valve with a half-turn first before using friction or spark lighter to create a flame coming from the torch. Reputable, American company you can count on. Slowly make your way to the other edge of the metal at a consistent speed, and follow the mark you made on the metal. How many gauges are needed on the acetylene bottle?
