Posted 15 Jan 2021 (edited) How can I lay a MIG weld bead like this? Is this very thin filler (.025?) and an exceptionally low current setting? Edited 15 Jan 2021 by Supermotive added a picture Share this post Link to post Share on other sites
Posted 15 Jan 2021 Practice Practice Practice.Yes smaller filler wire will helpThe weld at the bottom looks like its packed full of porosity Might just be the photo too. Share this post Link to post Share on other sites
Posted 15 Jan 2021 that welder and gas combo should work great for that type welding. Can you just turn your heat down? Share this post Link to post Share on other sites
Posted 15 Jan 2021 .025" wire 20-30 CFH on the flow. Do you have a separate control for wire speed and voltage? Welding the thin tubing just takes practice and a developed eye. It gets especially fun when you start welding different thicknesses together. Share this post Link to post Share on other sites
Posted 16 Jan 2021 Pretty much everything TJay said. I think pure argon is going to make matters worse, C25 works well. Use the .025 wire, your machine should have a chart with setting guidelines, I have found them to be pretty much spot on. 1 person likes this Share this post Link to post Share on other sites
Posted 16 Jan 2021 (edited) Find some material the same thickness as the tubing you intend to weld and set up various types of weld joints with it and start welding them up, once you have that mastered you will be ready to start practicing on the tubing.Something like this makes excellent practice.
