Stainless Steel with Hypertherm 1650

[waterfxmatt]

We primarily cut 10 and 12 gauge 304L SS on a Dynatorch table.

I am using the fine cut 40 amp tips, and using the settings in the manual...but my cuts leave much to be desired. What would be the recomended Amps, voltage, IPM, etc for these two materials?

Thanks in advance for the help.

Follow the specs in the manual.....it is more important to ensure the standoff distance is adhered to as opposed to setting the arc voltage. If you look at the Fine Cut specs in your manual...you will see that the torch needs to ride at .010" off the plate for stainless. I find that most users leave the height at the same (.080") that they use for mild steel.....and that will produce an ugly cut on SS.

Often...the arc voltage reading for different torch height control systems will vary due to system design and circuit board calibration. Adjust the voltage to achieve the physical height recomended in the Hypertherm cut charts. It is also a good idea to use the 220404 deflector when cutting thin stainless as this deflectore extends slightly past the nozzle....protecting the nozzle from plate contact and improving cut quality. The speeds suggested on the FineCut charts are correct......if you go slower....expect a drossy cut.
