Quik fuel diffuses
Bernard Quik Suggestion gasoline diffusers have a positive halt which secures the Quik Suggestion make contact with ideas in a fix situation for remarkable repeatability and steady excellent welds. The posture of the call suggestion within just the nozzle, commonly referred to as the call idea recess, can also enjoy a very important element. The accurate call tip recess place assists to decrease extra spatter, porosity, insufficient penetration, burn-as a result of or distortion when welding on thinner products. Although the excellent get hold of idea recess posture differs in accordance to the application, a normal rule of thumb is that as the welding existing will increase, then the recess need to also boost.
The chart below is a manual demonstrating which Quik Tip diffuser should really be utilized.
| Recess/
Extension |
Amperage | Wire Stick-Out |
Course of action | Notes |
| 1/4” Recess | >200 | 1/2 – 3/4” | Spray, high-present pulse | Metal-corded wire, spray transfer, argon-loaded combined gas |
| 1/8” Recess | >200 | 1/2 – 3/4” | Spray, higher-recent pulse | Metal-corded wire, spray transfer, argon-loaded blend gas |
| Flush | <200 | 1/4 – 1/2” | Short-circuit low-current pulse | Low argon concentrations or 100% CO2 |
Quik Thread system
With the Bernard Quik thread system, removing the nozzles from the diffuser could not be simpler. Just a quick twist is all it takes to remove them for either cleaning or replacing them.
