Chinese Plasma cutting techniques

go to see Welding Machine for Chinese Plasma cutting techniques

I regretfully bought a Chinese Cut40 plasma cutter a year ago. (I've had 2 bad ones out of 3)  Anyway that mistake aside I figure I might as well use it and get better with it.  I've cut some pieces out of 1/4" plate with it and it does pretty good hower  I think my cutting techniques are lacking.  The Tips I have on the machine now are short and look like drag tips but I dont use them that way I normally hold the torch 1/16-1/8" off the materal and cut that way.  Does anybody know if these are drag tips? Or if they make any?  Or has anybody rigged up a roller type setup that keeps distance even?  Anybody got any recommendations on cutting techniques with these things?  Angle of operation and air pressure etc?  Thanks.

Replyarry could probably chime in,But on ebay,i saw some tips and electrodes for the cut 40,came in a 10 pack,if i can remember,And they were cheaper than I could but them for,and resell them,so I bought a 10 pack!!!!!!!Got to the job,put a new set in,and cut 4" of 11 ga..WTF???????????,Looked at them,and there about a 1/16 shorter,,and a smig thinner,well the whole 6 that I used,same thing,,So But the real replacements!!I always leave my air water seperayor cracked a hair,and always drag rite on steel,I found staying off the material,it eats up consumbals!,Hope this helps,Jack

Replyarry,I never looked But when i had my miller spectrum 500 they never had a part # on the accual tip,ot electrode,only when i started buying from centracut in new hamphire,was the # stamped on,although you need a microscope to read them.!Alot of the time i just use a spare 60 amp torch,they say they dont work on the 40's,But ive had no problem,especially when your on the road,and somehow,when you have 3 different guys working for you,and one uses the spares.and dont say any thing,well you all know the story!,Jack
Reply:Thanks for the responses guys.  before I read these posts i just tried dragging the tip and wow the machine cuts so much better and the tip wasn't ruined after one run.  I'm much happier with this thing now.
