Bernard D118Q Diffuser Overview

The Bernard Q3015TE5EMC welding gas diffuser uses the D118Q Quik Tip design for MIG and flux-cored processes. It fits Bernard BTB, Clean Air, Dura-Flux, FILTAIR, Q-Gun, S-Gun and W-Gun series torches. The threaded connection secures the contact tip and nozzle for consistent gas coverage.

Installation and Common Issues

Thread the diffuser into the torch head by hand before final tightening with a wrench. Cross-threading the connection is the most frequent error and will leak shielding gas. Verify the 1/8 in recess alignment so the contact tip seats correctly without forcing the Quik Tip nozzle.

Compatibility Check Before Ordering

Confirm your torch model matches Q3015TE5EMC, Q4015TE5EMC, Q4020TN5ELC, S3015TE5HMC or S5015GH5IMC. Ensure you are using Quik Tip series contact tips and nozzles, not standard slip-on styles. Check that your welding process is MIG (GMAW) or flux-cored (FCAW) as listed.
