'Doggy......how thick of metal will it cut?
From the Hobart website
max output of 27 amps at 92 volts
cut capacity - 'rated' for 3/8" steel at cut speed of 14 ipm
'max' listed cut capacity of 1/2" steel at cut speed of 6 ipm
max listed 'severance' capacity is 5/8" steel
reduce thickness rating up to ~30% for cutting highly thermally conductive materials (aluminum, copper, etc) compared to cutting steel.
As to the OP, ratdoggy, tips?
Use clean dry air (better cut and better consumable life).
Have some spare consumables on hand (Murphy says if you don't have any you will need them, if you have them you won't need them.

).
Try and maintain a steady travel speed while cutting (once the cut is initiated).
With a 'proper' balance of cutting amps and travel speed (for the workpiece material thickness), there should be minimal slag. If there isn't a 'clean' cut, check settings and practice more (see previous tip about keeping a steady travel speed).
Use PPE and good safety practices. You
are dealing with molten metal being sprayed around by pressurized air, after all. Oh, and that plasma jet is somewhere between 5-10+
THOUSAND degrees F (could go up to 20k to 30k degrees depending on actual operating amperage and jet design) in temperature. Keep that in mind, as the plasma jet will cut or damage
anything in it's operating path.
