Is it true that wire feed roller tension should be tightened until the wire stops with slight pressure?

Wire feed roller tension is crucial for ensuring a consistent and reliable feed of the welding wire during the MIG welding process. When the tension is set correctly, it allows the wire to be fed smoothly without slipping or causing inconsistencies in the weld. Tightening the tension until the wire stops with slight pressure ensures that the rollers are gripping the wire adequately without extruding or deforming it. This balance allows for optimal feeding and helps maintain an uninterrupted weld arc, which is essential for quality welds.

If the tension is too loose, the wire may slip, leading to interruptions in the weld and poor arc stability. Conversely, if it is too tight, it can deform the wire or cause excessive wear on the rollers, ultimately impacting the quality and integrity of the weld. Therefore, achieving the correct tension where the wire stops with slight pressure is critical for effective MIG welding.
