I am looking for a used Weld Pac. Anyone have any leads. How about other ideas for better choices- opinions on best unit to use, I have few patch panels to weld up, and could use it for the business as well... Just don't want to drop $500 for one right now. I want to use a shielding gas set up. I would post in the classifieds but nobody looks unless they want something. Thanks for the help.
