The guys in the shop did that same thing to a new kid in a machine shop I worked at. They actually let him try to drill a hole using a drill press into a piece of 3" thick steel. When he burnt up the bit, they made him take it to the shop foreman who told him he must have been running it too fast. Gave him another one and told him if he burnt that one up he'd probably get fired. Poor kid didn't come back after lunch, so we sent somebody to his house to get him, after we found out what happened. He took the bunch of clowns seriously and was already starting to look for another job.
As far as a welder, there are plenty of places to read about "what should I get" so all you have to do is find a few of those posts. We here at TBN will be proud to help you spend your money.
