How to Operate a Concrete Cutting Torch How to Operate a Concrete Cutting Torch
For a lot of different concrete projects, it is necessary to use a concrete cutting torch. It can be used for many different tasks, but typically you will need it to cut the shape and size of concrete or even metal. If you are new to this tool, you may want to take this step by step crash course in order to learn for your next project.
Step 1 - Prepare
Before you use this type of tool you need to make sure that you prepare as far as safety is concerned. Make sure that you always have a fire extinguisher nearby in case of any problems that may arise. Also, be sure that you are wearing boots, safety goggles and gloves so that you do not put yourself in danger. Loose fitting clothing is also something that you will want to steer clear of so that you do not accidentally catch it on fire.
Step 2 - Secure the Material
Make sure that you secure the material that you are cutting to make sure that it doesn't move around. You can use a clamp to do this or supports. Also, you will want to work on a metal or steel table or work space so that you don't damage the area that you are working on.
Step 3 - Mark the Material
Now that you have it secured, use a marker or pencil to mark the areas that you want to cut using the concrete torch. Make sure that you use a straight edge to make your marks or a ruler so that you can measure twice and cut just once.
Step 4 - Cut
Before you actually do any cutting, you will need to hook up the tanks to the right gauges. Hook up the red and green hoses together. The oxygen and the acetylene will hook up together. Be sure to use a wrench when you are attaching the hoses together so that they are tightened completely and secure. If you don't do this step with caution, the brass on the hose can be damaged. Then, turn off the acetylene off and the gas on. The pressure should never go more than 15 PSI, otherwise you run the risk of starting an explosion. Now, turn on the oxygen regulator. You can adjust it by opening and closing the valve. Begin by opening it completely, but then move it down slowly so that the PSI is around 30 or so, give or take 5. You can open the acetylene valve and turn it on. Then you will be able to squeeze the handle of the striker to light the torch. You want to keep adjusting the acetylene valve until you end up with a flame that is around 10 inches or so long and is a yellow color. Work the tip around the marks that you made in order to cut the material.
