    What to do if ESAB ET 301i AC/DC creates undercut?
    • B
      Brianna BryantAug 7, 2025
      If your ESAB Portable Generator is creating undercut, it means a groove has formed in the base metal adjacent to the weld toe that hasn't been filled. This can happen if: * The welding current is too high (reduce it). * The welding arc is too long (shorten it). * The electrode angle is incorrect (it should be at least 45° to the vertical face). * The joint preparation doesn't allow the correct electrode angle (allow more room for manipulation). * The electrode is too large (use a smaller gauge). * There's insufficient deposit time at the weave edge (pause momentarily to allow weld metal buildup).

    Why portions of weld don't fuse with ESAB ET 301i AC/DC Portable Generator?
    • K
      Kyle GrahamAug 14, 2025
      If portions of the weld run aren't fusing to the metal surface or joint edge when using your ESAB Portable Generator, it could be due to several reasons: * Using small electrodes on heavy, cold plate (use larger electrodes and preheat the plate). * Welding current being too low (increase the welding current). * Incorrect electrode angle (adjust the angle to direct the arc into the base metal). * Travel speed of the electrode being too high (reduce the travel speed). * Scale or dirt on the joint surface (clean the surface before welding).

    How to prevent non-metallic particles trapped in weld metal with ESAB Portable Generator?
    • R
      Robert NelsonAug 23, 2025
      To prevent non-metallic particles from being trapped in the weld metal when using your ESAB Portable Generator, consider the following: * If there's undercut from a previous run, clean the slag and cover it with a run from a smaller gauge electrode. * Ensure adequate joint preparation for penetration and slag removal. * Chip or grind out any irregularities if they're severe. * Use a smaller electrode with enough current for penetration, and remove slag from corners with suitable tools. * Clean the joint before welding. * Use electrodes designed for the welding position to control slag effectively.

    What to do if ESAB Portable Generator leaves a gap in the weld root?
    • T
      Tamara StokesAug 30, 2025
      If your ESAB Portable Generator leaves a gap because the weld metal fails to fill the weld root, it might be because: * The welding current is too low (increase it). * The electrode is too large for the joint (use a smaller diameter electrode). * There is insufficient gap (allow a wider gap).
