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.

Air pressure at around 70psi. No I don't think they make drag tips but I'll check.

Larry 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

Maybe you should buy a 1Torch for the thing. I see them on Ebay once in a while…

Yes Jack is 100% right..........there are some JUNK consumables out there,,, I unfortuately have recieved some of them myself mixed in with a large batch last winter.I do disagree with Jack thou on one thing,,,, there is NO SUCH thing as REAL replacements when it comes to consumbales from China.There are no "Riland" brand name consumables, there are no "GiantTech" brand name consumables etc etc, check your consumables do they say Riland or GiantTech on them and is their a part number on them? THAT ANSWER WILL BE NO! The many Chinese factories that make these inverter welding/plasma machines purchase the consumables from consumables/torch factories ( probably just as many consumables/torch factories in china as there are welding machines factories, prehaps hundreds ), so that being said yes you might be smart to purchase from the company you got the machine from ( at least then you can be sure that the consumables they are selling will actually work seeing that they are selling it to work in their machine and should want your return business).
Hope I made some sense:laugh:

Larry,I never looked:eek: 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

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.

Jeep,Glad your happy,if you want to do any gouging,like air arcing,ive found that strait down,and a tad away,washes the old weld,or whatever your gouging real nice,But you will use consumbables faster!,Jack:)
