MIG Contact tip M6 0.8mm

Description

Taurus BZ contact tips are manufactured from a hard and highly-conductive copper alloy. The higher copper alloy quality requires less frequent replacements which in turn saves on welder’s downtime and consumable costs. Contact tips are one of the consumables needing frequent replacement on a MIG torch. They are responsible for guiding the welding wire and transferring the current from the swan neck (conductor tube) through the MIG wire to the work piece. It is important to choose a correct size contact tip for the welding application to ensure the best welding performance. Using an incorrect tip size that is too big or too small can create problems such as micro-arcing, overheating, friction and wire jamming, all of which can lead to wire burn-back. Copper is naturally soft and when combined with heat and wire friction can lead to contact tip deformation. This in turn can lead to arc-start issues, burn-back and poor welds such as a lack of penetration. Contact tips need to be changed on a regular basis.
