Gasoline Cutting FAQ’s
YES …and MORE. The SUPACUT Oxy-gasoline system was originally designed as a VERY powerful cutting system and that is its primary strength. The starter set includes the explosion proof tank, fuel hose, oxygen regulator and hose plus cutting torch and tips to cut up to 4″ thick steel.
However if you want to heat, weld (or braze) there are also optional a heating torch and a welding torch available. If you need to cut or heat, oxy-gasoline is the way to go, as it has much higher performance and the running cost is a fraction of acetylene!
If welding is your primary need, yes you can weld with the optional welding torch, however due to the greater oxidizing nature of the oxy-gasoline flame steel welding is more challenging than with an acetylene setup and its extra power limits its suitability for lighter materials.
YES, The cutting torch can also be used for heating work, but if heating is the primary need the optional dedicated heating torch performs better.
MAYBE…..Depending on the job, the heating or welding torch can be used for heating pieces to braze large heavy gauge material. Not suitable for light gauge work, it just has too much power!
Oxy-gasoline is not a single product. The gasoline required is just regular gasoline you buy for your motor vehicle, same place you get fuel for your car or pickup. Kit comes with a specially designed explosion proof 4 liter tank and hose to connect to the torch. Oxygen requirement is same as oxygen for oxy-acetylene. You usually rent or buy a cylinder from a local industrial gas supplier.
Due to the properties of gasoline the gas vapor is about 4 times as heavy (dense) as oxy-acetylene so has much more “punch”
No pre drilling is needed. The SUPACUT is MUCH better at punching through metal than an acetylene system. As the vapor is approximately 4 times heavier/more dense than acetylene and the flame is almost 100% oxidizing, SUPACUT can easily cut a hole and has minimal heavy/hot waste (acetylene has about 30% molten steel waste).
YES. Oxygen is needed for the torch to function so a standard oxygen setup is required just the same as for an acetylene system. However, the SUPACUT uses about 30% less oxygen than an acetylene system.
NO. This will not work with compressed air. Like acetylene system you MUST have OXYGEN to achieve the temperatures required for operation
NO – The tank does not need to be pumped up or connected to a compressed air supply. The torch is designed in such a manner the flow of oxygen thru the torch creates a powerful venturi effect draws the gasoline into the tip, then mixing the gasoline and oxygen and the resultant vapor is ignited to provide the cutting flame
Gasoline consumption is TINY. As a simple example if you were cutting 1/2″ plate with a C100 torch (with a No. 1 tip), in one hour you should be able to cut about 100 ft of plate and use less than 1/4 Gal gasoline (approx. $0.75c gasoline cost)
