Troubleshooting

Why is my stick welding porosity?

Quick answer

Porosity in stick welding usually means gas shield interrupted — wind, empty bottle, loose fittings, or dirty/oily steel. For this process, dry your rods — damp flux is the usual culprit before touching anything else.

The specific fix

Dry your rods — damp flux is the usual culprit. The general rule: check gas first: flow, leaks, leaks at the regulator; shelter the arc; clean the joint.

Process checklist

  • Arc too long — stick wants a rod-width gap or less
  • Dragging too fast, leaving thin, weak, undercut beads
  • Not chipping and brushing slag between multi-passes — slag inclusions
