SNAG - How Is Your Cut 50

I'm curious if your unit has arrived yet and if you have tested it out.

My Cut60 arrived yesterday (dual voltage). I didn't have a spare 240V plug handy so I decided to try it on 120V. Wow. It was pretty dismal. It cut 1/8 and 1/4, but I could do a better job with a torch. Of course I have used a torch more. I didn't bother trying it on 3/8. Even on

220V I can't see it "cutting" the claimed 22mm. Maybe it will severe, but I think it would be a reach.

Maybe after I get a little more practice. I did find going to slow was just as bad as going to fast.

OK...

...after a stop at Lowes for a $15 plug and a switch to 220 its "better."

It cut 1/4" decently. With 3/8 it took slow deliberation. Then I grabbed the torch and made a cut. The torch is faster and cleaner, but the slag from the plasma cleaned up easier.

I think ON 110V even 1/8 inch was "meh!" Might be okay for sheet metal.

Admittedly I learned to melt and slag my way through metal with a torch about 40 years ago, and just made my first cuts with plasma yesterday.

I found on mine it made quite a bit of difference which tip you use. I tried to cut some 10mm steel with the tip fitted and it didn't go well but as I have a selection I changed to another of a different size and it cut easily and cleanly. I bought mine 2nd hand as an ex demo unit and didn't get a manual but the torch is common enough Seco Trafimet one IIRC. One problem I did have with it initially was the tip sticking internally, it uses air pressure to pull in the internal electrode when the plasma is initiated and over time the impact peened the body it slid in causing it to get pinched, a quick deburr and all good as new.

Do you recall if you went up or down in orifice size for the cut thickness? (Higher velocity air or higher volume air.)

10mm is a little thicker than 3/8 so good results should be duplicatable.

I just checked the size of the old one and the new one with my torch cleaning broaches as pin gauges and both seem to be 0.9mm, the old one measures slightly larger at 0.95mm, and the new one 0.9mm so maybe the old one is worn, the other difference is the new one is longer as I  might have been needing to use it against a template but I don't know if that makes a difference. Just noted the longer one has the end of the internal electrode at 5.5mm diameter and the old short at 6.8mm diameter. i have the longer ones in 0.9mm and 0.8mm so may have to set-up and see what difference it makes, the short ones I have in 1.0mm as well. Here are the ones that proved most effective
