Why Is My MIG Welder Popping? (and How to Stop It)

WebApr 1, 2009 · As the contact tip absorbs the heat from the arc, it loses its ability to transfer the current to the wire, resulting in increasingly poor welding performance. Excessive resistance anywhere along the circuit can result in a wide range of problems, including a sputtering or erratic arc, inconsistent weld appearance and frequent contact tip burn ... WebMay 17, 2024 · Loose connections and damaged cables impact the quality of the welding arc. Damaged cables can cause voltage drops and ultimately reduce the heat into the weld, and this contributes to inconsistent weld quality. Poor cable connections or cable conditions also can lead to spatter in the weld, increasing time and money for cleanup. bims assessment for hearing impaired

Inconsistent high residual current during the cool interval between each weld impulse was also observed. WebAfter the wheel leaves the tack/spot weld, it sees the tack/spot as just another seam weld and will weld normally till the next tack/spot weld is approached. Another issue that happens as the seam wheel approaches a tack/spot weld is a possible gap between the two work pieces. A gap can happen with or without tack/spot welds. bims aphasia friendly
