Question

drag to correctly order the steps for setting up an oxyfuel torch in the order they are performed. first turn on the cylinder supply valves and set the pressures on the regulators. gradually open the oxygen valve on the torch. open the fuel gas valve on the torch and ig- nite the torch using a spark lighter. fine-tune the flame using the torch valves. last

Explanation:

1. First, the cylinder supply valves must be turned on and regulator pressures set to provide gas supply.
2. Next, the oxygen valve on the torch is opened to start supplying oxygen.
3. Then, the fuel gas valve is opened and the torch is ignited to start the flame.
4. Finally, the flame is fine - tuned using the torch valves for the desired flame characteristics.

Answer:

1. Turn on the cylinder supply valves and set the pressures on the regulators.
2. Gradually open the oxygen valve on the torch.
3. Open the fuel gas valve on the torch and ignite the torch using a spark lighter.
4. Fine - tune the flame using the torch valves.
