If you'll be doing a good bit of this type of thing it might not be a bad idea to learn. You can get started for around 250 depending on the machine you get. I could show you the chart and teach you to use a SMAW (Shielded metal arc welder AKA stick) in an hour or two (basic proficiency of course, not make you a master or anything). No gas, no feed rates, no fuss, just learn a bit about the different electrodes so you pick the right one and refer to the chart for your amperage.
