    Default question about stick welder amps

    the question I have is about the amps. I asked about stick welding 1/2 mild steel before and everyone said to use 250 amps (for single pass). So I know this probably basic info, but could I use a 200a machine and just do multiple pass. I have access to a 200a machine. I don't need to weld that thick but 1 or 2 times a year, so if I don't HAVE to buy a 250a I would wait to buy it.
    Thanks Dean

    Unless your working on a skyscraper you should be fine with 1/8 7018 between 125&130amp dcrp, depending on your skill level.

    Default question about stick welder amps

    200 amps is lots for anything but gouging. Just multipass it

    Not sure why anyone would want to attempt welding 1/2" steel in a single pass.
    Multi pass is the way to go. If you require a full 1/2" weld, 5/32" rod will make quick work of it.
