To maintain weld positions and weld in the same place every time, the MIG gun neck used in a robotic welding system must stay in its expected position as an accurate tool center point (TCP) that provides consistent repeatability from part to part. A weak neck that easily bends during routine welding can lead to problems with system accuracy over time. Here are some ways to protect, setup and maintain the neck and help ensure that your system maintains optimal TCP with minimal downtime.
