cut quality of my hypertherm 45 on Plasmacam DHC2

[james.davis]

I can't seem to get my machine dialed in when I use the settings in my book to cut 16g mild steel the cuts are wavy.I've tried
slowing the corner speed down and I've replaced the loader springs.The lack of quallty in the cuts really shows up a lot when cutting letters out and around tight corners, if I slow the machine way down to about 200ipm the quality of cuts are better but then I'm dealing with a lot of dross.I had a 600 hypertherm on my Plasmacam DHC2 for years(with good qualiy cuts) and just changed over to a 45 .I haven't changed the belts yet.Any help would be much appreciated.

PS I'm using a machine torch and a "snap and cut" holder with my 45.

i am a newbie , but did you check youre air pressure? and maybe lower the volts some.

maybe the filter is a little clogged . I like 100-130 psi on the back of the machine .

I found the higher the psi the cleaner the cut. and the faster you can run.

just my observation so far

Thanks but I' m running a combined 2 tanks 140 gals. with an air dryer an filter set up at 125psi .I had everything cutting alright with my 600 it's just when I changed over to the 45 that everything went south.I'm pretty sure that something just needs to be set diff.just don't know what that something is
Thanks,
Jim

Could it be torch height to high? or volts to high? that's all I got . sorry

For finer cuts at lower speeds you can use the 30 amp consumables (there are cut charts in your Powermax45 operators manual). Since they are unshielded you will lose the ohmic contact functionality, but will get better edge quality and narrower kerf at lower speeds. Likely it is the PlasmaCam machine having issues cornering at the higher speeds required. I would also check the bearing way surfaces and ensure your machine has smooth motion. If you hold on to the torch while running thorugh a part program you will feel roughness in the motion, anything you feel will show in the cut.
