Jim Colt,

While ordering some consumables today I noticed that the 220755 cap is Counter-Clockwise and the 220756 cap is Clockwise. We have a custom 45 amp N2 and 80 amp N2 process for aluminum that cuts better than the air setup, but my question is which retainer cap is better for an N2 aluminum process? I had thought that the 755 was for N2 and the 756 was for air, but looking at the consumable chart the 45 amp N2 stainless uses the 755 cap and the 130 amp N2 stainless uses the 756. Also doesn't the swirl ring control direction? Or is this just referring to shield gas direction?

Thanks,
Colton

I suggest using the cap as the cut charts suggest. I remember during development we found that we could get better cut quality by reversing the swirl patter on certain thicknesses and types of material. I honestly do not remember all the details, however the cut charts outline where these caps are used, and for what materials.

Thanks, but there is no cut chart for what we are doing.
As a suggestion I'd like to see Hypertherm refine their aluminum processes for thinner materials. We have much better cut quality using our custom N2 and F5 processes on .060, .125, .188, & .25 Aluminum. While consumable life is a little shorter, the time saved in post processing is well worth it.

We'd be happy to look at your cutting specs. Honestly we pay less attention to thin aluminum cutting as it is a very small segment of where these systems are used.....we are always looking for suggestions.

Best regards, Jim Colt
