NO idea of the basic concept of what welding is all about
This guy has absolutely NO idea of the basic concept of what welding is all about. The purpose of a good weld is to melt the two base metals together, the wire is a filler metal, the purpose is to fill the void that the arc creates while melting the base metals. If the weld setting is to high , and your an experienced welder you will be able to see the puddle before it blows threw the base metal, this can be corrected with a faster travel speed or just stop and adjust the heat setting, but you should never start out with a cold weld. I would wager if the guy had hit the piece on the work bench a weld failure is certain. This is why buying a welder at Lowes and doing it yourself is ok for small jobs around the house. If its something critical, such as a trailer, where your safety or the safety of others is an issue take the project to a qualified welder with the proper equipment and experience.
