Been battling this all day, im cutting small 1.5 rounds out (edge start) and the drops are the parts i need, and the dross is mostly only on the round drops?
The cut quality is good, as long as i edge start, if not the tip is lost right on the start of the pierce and very misshaped due to the tip blowing out
its a heavy thick bubbly dross and is very hard to remove and some will not come off
you may have some moisture issues…the motorguard should be the very last item before the plasma…it is noit a very good unit to dry with…they plug up and corrode.
I have had, am putting back my full dryer system once my garage is done…
60 gallon compressor between the head and the tank I have a home built copper wall cooler…soon changing to a radiator type cooler with drip leg with auto drain…then into the 60 gallon tank…from the tank through a refrigerated dryer…then through a beaded desiccant dryer…then through the motor guard…
when I added the copper wall cooler I doubled my consumables life…then when I add my refrigerated dryer I added another 25% life to my consumable…
I live in Ottawa Canada and I deal with extreme temp variations and high humidity…and I can get over 800 pierces with this setup…even then I prefer to change out before they blow on the table.
I use the “used” consumable on the hand torch for crappy cuts
0.8 are 30 amp unshielded tips so you wouldn’t use them for 1/2". 1.0mm/50 amp tips and 1.1mm/60 amp tips can be shielded or unshielded. If your using 1.1mm/60 amp shielded tips with a CNC shield you need to measure the torch height between the tip and work piece not the shield and work. If the distance between the shield and work piece is more then .035" the torch height is way to high.
