Three factors contribute to excessive use of welding gases, according to welding research.
Selecting a contact tip system [as shown in this cut-away] that stays tight or has locking features can help improve electrical conductivity and provide better welds.
Trimming the liner to the correct length preventswire-feeding problems and keeps the contacttip from failing prematurely.
Select a nozzle with a smooth surface to prevent spatter accumulation that can lead to downtime and shorten the life of the component. Note, this cut-away shows the inside nozzle insulator.
