Any one have this unit? Pros? Cons? How effective is the built in air compressor? Would I be better with a 220 v machine for general home and hobby stuff. Most of my projects are 1/4 inch and less

Reply:Its perfect for home and hobby. But i agree its a great sheet metal machine
Reply:I bought a used Miller 125. I kept it for about a week. I was very disappointed and put it on eBay. I got more than my money back and bought a Miller 375. I use it for 1/8"- 1/4" with very good results. I have severed 1/2" but not easily nor cleanly.Burt _____________________Miller Syncrowave 250Millermatic 211Miller 375 Plasma Cutter Hobart Handler 12010FtDrillBit.com
Reply:I'm really going out on a limb here, because I've never owned a plasma cutter, and I'm not too sure what the advantages are (At least in what I do. Mostly mild steel).Is the cost of the plasma vs. O/A justifiable for most work? It seems to get into real money when you're talkin' heavier cuts with a plasma.Would it be a good route to maybe buy a low dollar/smaller capacity plasma, and stick with the O/A for thicker stuff?"Any day above ground is a good day"http://www.farmersamm.com/

Reply:farmersamm,As Ed/Broccoli cryptically mentioned, plasma can cut pretty much anything electrically conductive (meaning pretty much ANY metal). Steel, stainless steel, aluminum, copper, iron, whatever.O/A cutting of mild steel heats the metal to white hot and then introduces the oxygen cutting jet to get the steel to 'rapidly oxidize' AKA burn. But that methodology doesn't work for other metals like stainless steel or aluminum or copper, etc.Plasma uses electricity and compressed gas (usually plain old CLEAN compressed air). That's it. Not counting consumables. And with the appropriate sizing (amps of power) for the work thickness, plasma is FAST. A small Hypertherm PowerMax30 machine (30 amps of arc, only 21 lbs for machine and torch and cables but not air hose, about the size of two loaves of bread stacked on top of one another) is rated to cut 1/4 inch material at 33 ipm on mild steel and 24 ipm on stainless steel and 26 ipm on aluminum. Thinner material can be cut even faster, as in sheet metal at hundreds of ipm (18 ga mild steel at 394 ipm using full 30 amps). That machine can sever thicker material at slower speeds. Bigger machines can cut thicker material (IIRC Jim from Hypertherm did some recent demo/trade-show and used a slightly bigger 45 amp machine to sever through 1+ inch thick material!) But the machines have an expensive-to-very-expensive initial price.With O/A cutting, you need the torch set plus the tanks plus the gas in the tanks. It's portable, and can be used for other things as well. For cutting thick mild steel, you still need a big torch and big tanks.Navy, as mentioned the machine you are talking about is pretty much for sheet-metal thickness. You have to get into the 30-amp class machines or better to do 1/4 inch. Hypertherm PowerMax30 or 45, Miller 375, or others. Or go for MORE POWER! Arrrr! The best laid schemes ... Gang oft agley ...
Reply:My little Hobart 12 amp machine works very well. One key is to ditch the shielded cover and use the exposed tip. Holding a bit of standoff improves the cutting thickness of that machine. I have the Esab 125 handyplasma 11 amp version / 18 amp Esab 250. (which I really like for a 120 volt machine) I also have a 100 amp Thermal 151 for those stubborn jobs. I will cut some .250 mild steel with my Hobart today. I bought mine for $225.00 used and it was almost mint.I have to say I like mine very well:

Reply:I think my Harris will cut up to around 2" with a no. 2 tip. So far I've been lucky not to have to go any bigger. Hate to watch the dial visibly spin on the O2 bottle"Any day above ground is a good day"http://www.farmersamm.com/ |
