We are going to have some iron work installed to help keep our home secure. What we are trying to do is raise the height of our wall by a about 15 inches. The iron work will go on top of the concrete wall (fence) we have surrounding our yard. I am sure this will involve some welding and I took a look at machinetools.com for welding equipment. I did not know much about welding equipment, but I know that along with the welder itself you need. No matter what kind of welder and welding equipment that is needed for the job, I am sure it can be found at machinetools.com.
