Welding gun nozzles play a critical role in the welding operation. Having the right nozzle for the job can help reduce weld defects, rework and associated downtime — while also extending consumable life. All of these factors impact the bottom line.Unfortunately, like other MIG welding consumables, the importance of selecting the right nozzle is often overlooked. In any welding application, the right shape and style of nozzle, however, can have a significant impact on the quality, productivity and overall cost of the welding operation. Knowing how to store and handle nozzles properly can also help improve their overall performance. Consider these tips to get the best results

• The higher the welding current, the larger the bore size of the nozzles
• Consider standard duty nozzles for low welding current applications to save money
• Use a heavy-duty, copper nozzle for the high heat1 applications
• Brass nozzles have good spatted resistance and can take more manual abuse than copper nozzles at medium and low heat applications.
• Brass loses most merits when the temperature is above 450 degrees Celsius (840 F)
• If heavy spatter is expected (i.e. galvanized base metal, or, oily surface, or, short circuit weld, 100% CO2, etc.), use a short nozzle with a larger bore size
• Brass material is also a good choice depending on head
• Straight bore nozzles are recommended to achieve the most effective cleaning with a robotic nozzle cleaning station or reamer
