Next time you need to have something welded, consider RENTING the welder you need. Dependo Rent-All will be happy to help you select the right welder for the job. They can show you how to use it. It's not that hard, believe me.
YOU CAN DO IT YOURSELF !
Yes, the first thing you weld will not look as good as the second or third thing you weld but "practice, practice, practice".. If you don't like the way it looks, just grind it off and start over.
Renting makes sense on an expensive tool that you don't need often. You might know how to weld with a stick welder but never tried a mig or tig welder. This is a chance to give it a try. I love to weld. It won't look as good as a pro but I can say I did it and SO CAN YOU.
