Which AccuLock Consumables Are Right for Your Welding Operation?
Based on discussions with customers in key industries, we found that MIG gun consumables challenges differed depending on the quantity and mix of welding applications in each customer’s facility (i.e. semi-automatic, robotic, fixed automatic).
If you have all semi-automatic or automated arcs, the choice of AccuLock consumables is more straightforward. However, with the increasing adoption of automated welding to address the ongoing welder shortage, many operations now have a mix of welding application types.

If you are experiencing the following welding challenges, we recommend using AccuLock S nozzles, diffusers, liners, power pins and power pin caps with AccuLock contact tips:
- Birdnests
- Burnbacks
- Erratic arc
- Short contact tip lifespan
- Excessive rework
Many of the issues above can be traced to MIG gun liners that have been trimmed to an incorrect length or that pull out of position inside the MIG gun creating gaps along the wire feed path.
