Installation Notes

Liner replacement is performed by qualified welding technicians familiar with MIG gun maintenance procedures. Power down and disconnect the welding gun from the wire feeder and power source before removing or installing the liner. Follow the gun manufacturer's liner installation sequence to ensure proper seating and trim length, as improper liner fit is a leading cause of wire feed irregularities. Refer to Bernard's service documentation for Q Gun Quick-Change liner replacement procedures.
