    replied to weld shrinkage and fixtures
    Is the part coming out to acceptable tolerances when he does it? If so leave him alone. If not then obviously something needs to be tweeked. All designs require some different thinking as to how it will distort. Sometimes in a production environment it pays do do several pcs differently to see which...

  • Most flux core calls for knurled rollers, not smooth so you can set the tension slightly less to not crush the wire, especially if one roller is flat. Blow out the liner and see if you can push the wire through by hand. You can use a torch tip cleaner to clean up mig tips.

    replied to Air compressor recommendation
    I use an IR wheelbarrow compressor. https://www.tractorsupply.com/tsc/pr...air-compressor Although it is smallish it does what I need. I do light gouging with 3/16" carbons using an arcair K2000 torch which uses minimal air. Not doing heavy gouging just some cracks or some shanks. It just barely...
