Colorado Welding Supply is where I have to shop for my son's Christmas and Birthday presents. They are the only people in town who carry exactly what he needs at good prices. Their gas prices are not as good as AirGas but they are MUCH nicer and easier to deal with, therefore I'm willing to pay a little bit more. Great for LARGE orders or just for the hobbyist. My son is a blacksmith/metalworker/welder in his spare time and Colorado Welding Supply has every thing he needs to outfit his shop and create his wonderful works of art.
