Pocket 25 Plasma Cutter

wrote: In Febuary, a guy gave me a Daytona Mig Pocket 25 plasma cutter (rebadged Cebora 920) No one knew if it worked, and the defuser, nozzle and electrode had been badly fried. I suspect because they attempted to fire it up without air. This unit is a "pilot arc" machine, no High Frequency start. The consumables were a bit pricy, so I stuck it up on the shelf until another day. 2 weeks ago, I contacted Daytona Mig (unfortunately it appears to be the only source for consumables, and not knowing if this even worked..I ordered one of each consumable, electrode, nozzle and defuser. It they showed up during the week while I was on the road...so today, I dusted it off, ran an air hose and plugged it in. This torch requires you to press the tip against the work, then press down lightly while springloaded switch kicks in something and the plasma starts. Which it didnt do until I replaced the ****ty OEM ground clamp and hit the contact area with a wire wheel. It works~!!! The downloaded manual makes no reference to maximum thickness of work. It cuts 1/8" fine, severs 3/16 if its nice and clean, and simply cuts a groove in 1/4" material. Not as powerful as Id hoped for...sigh...being able to cut 3/8ths would have been the tits, or even 1/4" material., but I can use it for stuff Id normally have used a jigsaw or bandsaw. Shrug Any tips for using a small plasma cutter? One assumes that the material must be clean , based on trying to cut some rusty 3/16" stock. Straight up and down except when piercing... Anything else I should know? Gunner, plasma noobie A 24 amp machine like that should cut 3/16" cleanly and sever 1/4". You do need a stiff 20-amp 120-volt supply, though. Running it on 14-gage wiring or (worse) an extension cord would definitely diminish its capacity. |

Its on a 30 amp breaker..and wired with 10ga wire from the 60 amp distribution panel 12" away (yes...inches) Im a very good industrial electrician. Ill have to try some clean 1/4" plate. What I tried was rusty/nasty Gunner Political Correctness is a doctrine fostered by a delusional, illogical liberal minority, and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a turd by the clean end. |
