I used em for some brass and bronze as well as some combo selections for my small mill and lathe. Prices sre OK, just watch your freight. Otherwise I have no problems or issues with em.

I make repairs at a track on car frames and roll cages between heats and the repairs have to be fast, sound, and proper. TIG welding is too time consuming for making such repairs in this situation. I have never MIG welded 4130 before, only TIG. Can anybody tell me what the do's and don'ts are of MI...
