Tweco GAS DIFFUSER QTR56-SW | 15601125

Increase productivity with longer life front end consumables using Tweco® Spray Master MIG gun series with Eliminator front end consumables. Combined with all the advantages of the Spray Master, this new line of MIG guns helps the shop floor lower usage cost with improved operator appeal. Selecting the right nozzle for a welder’s preferred ‘nozzle to tip relationship’ on a MIG gun is generally based on the application and the welder’s daily welding routine.

• Used in medium to heavy duty welding application up to 600 amperes
• Machined from 360 brass alloy bar stock to ensure consistent dimensional stability
• Designed to be used with the REL24 series robotic/fixed automation nozzle assemblies
• Easy identification – Part No. rolled stamped on the outside surface
• Designed to work with robotic/fixed automation MIG conductor tubes
• A course thread is machined on the outside surface to allow the nozzle assemblies to thread over – holding the nozzle in place during the welding process
• Gas diffuser has a silicon O-ring to seal against the nozzle assembly

Recessed Tips are generally used for higher heat applications where longer electrical stick-out is required, or in cases where the nozzle may touch the work piece (tack, spot, and stitch).
Flush Tips are generally used where a shorter electrical stick-out is used sometimes resulting in shorter/tighter arc lengths. This brings the tip closer to the work piece.
Protruding Tips are generally used when welding open root pipe or any joint that requires the welder to get into a tight weld joint. However the down side to this is the chance of arcing the tip to the work piece, which could damage front end parts resulting in downtime needed to replace.
