It’s good to have friends pushing you in the right direction. We use a Miller 255 it seems to work well. I have another spoolgun for my Miller passport plus but haven t used it since the 255 showed up. Here’s a link to a toolbox welding cart we made for the 255.
Ironically it was all tig welded.
Here is another project. Ended up make making some curtin rod hangers and rod for the wife from refrigeration line offcuts. No electricity or money was used while making these parts.
