One piece solid copper drilled scarfing nozzle of nozzle mix design.  This nozzle produces a wide flat gouge path.  This solid copper scarfing nozzle has been fitted with a Stellite wear ring to help prolong the nozzle life.  This H4 160/10 nozzle is suitable for use SAF style scarfing torches.

As with all gouging or scarfing nozzles car should be exercised when forward gouging to ensure the dross is being blown forward, try not to allow the molten dross to sit on the nozzle tip face as this will cause the nozzle to burn prematurely.

It is important that the nozzle has sufficient oxygen flow to enable the dross to be blown ahead of the gouge path, high flow equipment has to be used so no restrictions are encountered, scarfing operates best with lower pressures and higher flows - it is the volume of oxygen that is important to the gouge path being achieved correctly plus of course the technique and skill of the artisan.

Should internal burning be encountered then it is important to shut off the oxygen first and then the fuel.  If possible quench the nozzle and torch head in clean water then establish why the sustained backfire happended. Inspect the nozzle and torch the refit and test.

Nozzle shown is the H4 size 160/10
