Operating Instructions for Victor Torches

A Victor torch is an excellent tool for a homeowner's shop needs, since it will provide a full range of welding, cutting and heating operations. Built-in flash arrestors and reverse flow check valves add extra safety, but using a torch is not a job for amateurs. Proper safety equipment must be worn at all times, including shaded goggles. The work area must have a fireproof floor, benches and work tables must have fireproof tops and heat-resistant shields must be used on nearby walls. A handy fire extinguisher and a clean work area free from combustibles is a necessity for safe operation.

Welding Preparation

Sparks can fly during a welding operation, so protective gear is essential.
  1. Check valves and connecting hoses for any grease or oil buildup and clean, if necessary.

  2. Connect the oxygen hose regulator to the torch and tighten with a wrench.

  3. Slowly open the cylinder valve. Shut the valve off, then quickly open and close the valve to dislodge any loose contaminants. Don't stand directly in front of behind the regulator during this process.

  4. Adjust the oxygen valve intake to allow 3 to 5 PSIG to flow through the hose. When the intake gets to the proper setting, allow it to flow for 5 to 10 seconds and shut it off.

  5. Inspect the torch handle head, valves and hose connectors for any oil, grease or damage. Inspect the handle for dents or burned seating surfaces. Check the flash arrestors and tighten if needed. Attach the hoses to the torch handle and tighten tightly with a wrench.

Welding Setup

  1. Check the thickness of the metal to be welded and select the correct size of tip from the tip selection chart that comes with the torch.

  2. Open the oxygen valve and adjust the regulator to the required range, according to the charts included with the torch. Then close the torch handle control valve to purge the oxygen hose.

  3. Open the fuel valve on the torch and adjust to the required range. Close the torch handle control valve to purge the fuel line.

  4. Hold the torch in one hand and the spark lighter in the other. Be certain the lighter is away from the tip and not obstructing gas flow. Open the torch and ignite the gas.

  5. Continue opening the fuel valve until the flame stops smoking. Open the torch oxygen valve until a bright neutral flame is achieved.

Welding Operation

  1. Clean the joints to be welded.

  2. Place the metal to be welded on the worktable and tack the pieces together at the ends, to hold them in proper alignment. If the pieces to be welded are long, you will need to tack them together every few inches. Hold the torch at a 45-degree angle to the joint.

  3. Move the torch nozzle over the edges of the joint and rotate in a circular motion until the metal from the two sides melts into a molten puddle. Dip the end of a filler rod into the puddle, melting it into the puddle.

  4. Move the nozzle forward after 1/16-inch of filler rod has melted into the puddle.

Welding Completion

  1. Shut off the torch oxygen valve. Then shut down the fuel valve. Close both cylinder valves.

  2. Re-open the torch handle oxygen valve and release the pressure from the system. Close the torch oxygen valve. Turn the adjusting screw on the oxygen regulator counterclockwise to release pressure.

  3. Re-open the torch fuel handle valve and release the pressure from the system. Close the fuel valve. Turn the adjusting screw counterclockwise to release pressure.

  4. Check the gauges after a few minutes to assure that everything has been shut off completely.
