Interpretation of Common Problems in Wire Feeding Machine - Mismatch between Voltage and Current during Welding

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 problem that the wire feeder manufacturer is going to talk about today is that the voltage and current do not match during welding.

Cause: Failure to adjust according to the specified welding specifications and lack of experience during welding.

Causing phenomenon: When the current is too high and the voltage is too low, intermittent unstable welding will occur, welding spatter will be too large, and the welding wire will transition to the molten pool with loud and chaotic sound. When the current is too low and the voltage is too high, there will be excessive welding smoke and dust, and the sound of the welding wire transitioning towards the melt pool will be small and sharp. The welding wire and the conductive nozzle will melt and stick together at the same time, making it impossible to weld.

Attention: According to production needs, adjust according to welding specifications to ensure that the welding wire melts in a timely manner when entering the molten pool, and the sound of the welding wire transitioning towards the molten pool is uniform.
