I am thinking about buying 8x10 pieces of sheetmetal, which one of my
contractors is going to be joining up. We were thinking of buying a
acetelene torch /w fuel, but that would cost around $200.
Are there other cheaper ways of joining together those pieces. My
worker (who is experienced with using a welding torch) told me that
the previous job was done with a butane torch and uses aluminum as the
joining agent. Is this common and reliable?
