Interpretation of Common Problems in Wire Feeding Machine - Improper Use of Wire Feeding Machine Pressing Wheel

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 wire feeder manufacturer wants to talk to you about today is the improper use of the wire feeder clamping wheel.

Cause: When using the wire feeder clamping wheel, it should be matched with the welding wire. For solid carbon steel welding wire, steel wheels should be used, while for flux core welding wire, ceramic wheels should be used, and the groove model should match the diameter of the welding wire. The pressure should be adjusted according to the usage requirements and should not be too loose or too tight.

Causing phenomenon: When using ceramic wheels for carbon steel solid wire welding, it can cause the ceramic wheels to wear out too quickly. When steel wire feeding wheels are used for flux cored welding, the flux cored welding wire will be compressed and cracked, causing the flux to leak out and unable to be welded. When the diameter of the solid carbon steel welding wire is larger than the diameter of the groove of the wire feeding wheel, it is easy to create indentations on the welding wire, causing the circular section of the welding wire to deform. The welding wire with indentations will be stuck when passing through the conductive nozzle. When the diameter of the welding wire is smaller than the groove diameter of the wire feeding wheel, the friction between the wire feeding wheel and the welding wire is insufficient, causing it to slip and unable to feed the wire normally. When the wire feeding wheel matches the diameter of the welding wire, the pressure of the wire feeding machine's clamping wheel should also be appropriate. When the pressure of the wire feeding wheel is too high, it will cause deformation of the welding wire. When the pressure of the wire feeding wheel is too low, the friction between the wire feeding wheel and the welding wire is too small. When the welding wire is subjected to resistance in the wire feeding hose or on the conductive nozzle, unstable wire feeding phenomenon will occur.

Attention: Use steel or ceramic wire feeding wheels as required. The groove type of the wire feeding wheel should match the diameter of the welding wire, and the pressure should be appropriate. The groove of the wire feeding wheel should be cleaned regularly.
