Installation & Setup Oxygen & Acetylene Filling The Mobile Max is shipped with the tanks empty. Therefore, you will have to take the tanks to a local welding gas supply distributor to have them filled prior to welding. Different welding gas suppliers handle tank filling differently; some will fill the tanks while you wait while others require a tank exchange. You will need to select the type of supplier you prefer. Attaching Regulators and Hoses 1.
Installation & Setup It is important that all fittings have been tightened with a wrench by this point. Insure the tank valves, regulators valves and torch handle valves are turned to the off position. Opening Valves 1. Attach the welding tip and tighten with a wrench. 2. Slowly open (clockwise) the oxygen cylinder valve to allow oxygen to flow to the regulator. Once the regulator begins to register pressure, open the valve an additional 1 to 1 1/2 turns.
Operation WARNING At this point the operator should be wearing appropriate protective clothing such as gloves and goggles. Once a neutral flame has been achieved the torch is ready for welding. Lighting the Torch 1. Open the acetylene control knob on the torch handle just enough to let some gas flow. Heat Envelope Acetylene Feather 2. Holding the striker close to the welding tip squeeze it a few times to create the sparks required to light the acetylene.
Operation Shutting Down 1. Using the acetylene control knob turn off the flow of acetylene to the welding tip. This will allow oxygen to continue to flow and will insure any debris that may be in the orifice is blow out. 2. Turn off the oxygen using the oxygen control knob on the torch handle. 1. Remove the welding tip from the torch handle and attach the cutting head. Tighten with a wrench. 2. Insure that the both the acetylene and oxygen control knobs on the torch handle are closed (clockwise). 3.
Operation 8. Check all connections for leaks. Leaks can not be seen, therefore, use soapy water on all connection points to insure there are no leaks. 9. Open the oxygen control knob on the torch handle two full turns. No oxygen should flow at this time because the oxygen flow is controlled by the valve on the cutting head. 10. Insure oxygen flows by turning the control knob on the cutting head a quarter of turn. Quickly close the valve after confirming oxygen flow. 11.
Operation 3. Press the oxygen cutting lever briefly to insure oxygen is flowing through the cutting hole. 4. Further adjustment may now be needed to insure a neutral flame in the preheat holes. Generally a reduction in oxygen. 5. The torch is ready for cutting. Shutting Down 1. Using the acetylene control knob on the torch handle turn off the flow of acetylene to the welding tip. This will allow oxygen to continue to flow and will insure any debris that may be in the preheat holes is blow out.
