Interpretation of common problems with wire feeder - uneven thickness or burrs of welding wire

During welding, the wire feeder often experiences unsmooth and uneven wire discharge, which can cause difficulties in welding and directly affect welding quality. The weld seam that should be welded at once should often be divided into several sections before welding can be completed. So what are the problems we often encounter in our daily welding? The following experience is for reference only.

The issue that the welding wire machine manufacturer is going to talk about today is: uneven thickness or burrs of the welding wire.

Cause: Due to unqualified wire drawing equipment during the production of welding wire.

Causing phenomenon: When welding, uneven thickness or burrs of welding wire enter the wire feeding hose of the welding gun, causing friction and vibration with the hose wall. When the vibration gradually approaches the welding gun and enters the conductive nozzle, unstable wire feeding, intermittent welding, or jamming phenomenon will occur.

Attention: Intermittent welding may occur after replacing the new conductive nozzle. Before welding, a matching model of conductive nozzle should be used to inspect the welding wire. It was found that the welding wire that did not pass through the clamping wheel of the welding machine was not smooth when passing through the matching model of conductive nozzle, which must be due to uneven diameter and thickness of the welding wire. The welding wire should be replaced.
