miller 320 abp

admin

hi everyone,please help.i may be purchasing a miller 320 a/bp. is this a good machine. it has the white face on it. what is it worth. what should i pay for it.what i need to know is it the same thing as the 330 a/bp?what are the exact differences if any?will the 320 weld 1/2 aluminum? will the 330?does the 320 have the same response time as the 330 with starting the arch? the 330 is instant.
Reply:The 320 is the smaller version of the 330. The 320 is rated at 60% at 200 amps, the 330 is rated at 60% at 300 amps. Max amp rating of the 320 is 300 amps in GTAW vs 435 amps for the 330.I've never used a 320, but have done some tig running a 330. My guess from looking at the manual is that the machines should be very similar as they share the same manual.Near me most of the 330's I see listed run between $500-800 depending on what comes with the machine and condition. I've seen some people who want as much as $1500 for them, but I'd be surprised if they get it. I've seen a few 320's listed, but can't remember exactly what they were asking. My guess is they were in the same rough range as the 330's, thus I didn't really pay that much attention to them.http://www.millerwelds.com/om/o340j_mil.pdfLast edited by DSW; 12-01-2012 at 04:15 AM..No government ever voluntarily reduces itself in size.

Reply:300 vs 435. is that a huge difference? is it like the 435 will weld 1/2 aluminum and the300 will weld 1/4"i guess what i am asking is how much more power is the 330? is it really noticablethanks
Reply:There aren't a ton of people who usually need amps that high for tig. Heavy alum would be one of those places where more would be better. Most people who are probably doing heavy alum are most likely doing it with pure helium and DC though if using tig.Other high amp uses would be carbon arc gouging or heavy stick welding and chances are with those, more is probably better. It doesn't sound like these are things you are likely to be doing however.Most guys I know on average, can get by with 300 amps for tig. That's more than enough to do 1/4" alum in AC. If I was feeding the machine a steady diet of 1/4" alum, I'd probably go with the larger machine for duty cycle reasons rather than max amps. 200 amps will do 3/16" alum in AC.A better idea just what you want/need to do with the machine would help..No government ever voluntarily reduces itself in size.

Reply:You simply can't kill a 330 if you take care of it..I run mine on "Kill" 95% of the time and I use it all day long.That reminds me..I have a pile of aluminum cooling chambers to weld up on Monday..I get all the fun jobs!...zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.

Reply:i am asking these questions because my brother has a 330. it is awsome. i came across this 320 with water cooled torch, the machine, tank, peddle, and home made water cooler for 225.00.the machine is a 1964.i called a miller repair guy this morning and he says the 320 is only comparable to a syncrowave 200. is this true. if it is the machine does not have that much power.i will be welding a lot of 1/4" steel, roll cages, body panels. i want the power their if i need it. (like having a v-8 that will lite the tires up at 60mph if needed)i just want to make sure i am not buying a machine that will not satisfy my needs for the welding i will be doing. it is also a little over 2 hrs away.I know the 330 will do 1/2 aluminum. I just cannot find really any info on the 320,(its all 330) so i just want to be sure it is a very good machine. (like the 330)will the 320 do thicker than 3/16 aluminumRE.7A749 "Not trying to be smart, but most guys familiar with TIG welding 1/2" AL know what kind of machines do it & the amperage required."my feelings do not get hurt very easily so what ever is on your minds let me know please. it only will help me out. (people on here know more than i do. so i will listen)thanks againLast edited by tbird; 12-01-2012 at 10:58 AM.
Reply:I think he means the Syncrowave 250 not the 200. My Syncro 200 is rated at 40% at 150 amps and tops out at 200. The Syncro 250 is rated at 200 amps at 60% duty cycle and tops out at 310 amps..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear.

Reply:it is for $225.00. welder, torch, water cooler(home made), tank, foot peddle. i do not care how old it is. old stuff is better than this new junk. there are  parts still available for these machines. these old machines were also built not to break.so are you saying the 320 is comparable to the 250 dx sycrowave of today?as for the power. i will run what ever i need to get the most power out of itif i run helium will i get a hotter burn to go thicker on the aluminum or steelthanks
Reply:That machine is going to have more power than you ever need.   I can weld 3/8 aluminum on the medium power setting which is about 250amps.   the pedal alone will bring about $150 on ebay,   the cooler is worth a couple hundred and if you take the time to strip out the copper there is about 80lb of copper in one of these machines.   I just sold a HF panel on ebay for a 330 for $125.    just taken as one piece to scrap yard it will get ya about $100Tiger Sales:  AHP Distributor    www.tigersalesco.comAHP200x; AHP 160ST; MM350P,  Spoolmatic 30A; Everlast PowerTig 185; Thermal Dynamics 60i plasma.  For Sale:  Cobra Mig 250 w/ Push-pull gun.  Lincoln Wirematic 250

Reply:yes that is why I listed the amps.   Also you can use preheat or an Argon/helium mix  to get hotter but you will find once you get a few inches into whatever aluminum you are welding you will be backing off the pedal a lot due to the heating of the base metal.You have to know how to weld properly then know how to use the machine...  Go look at some of Zapster's welding as its all done on a Miller 330 ABP. he flat out will prove its the operator not the machine that makes the weld...Tiger Sales:  AHP Distributor    www.tigersalesco.comAHP200x; AHP 160ST; MM350P,  Spoolmatic 30A; Everlast PowerTig 185; Thermal Dynamics 60i plasma.  For Sale:  Cobra Mig 250 w/ Push-pull gun.  Lincoln Wirematic 250
Reply:Uh... You haven't bought it yet? Where is it?   Kidding of course. It won't be around long at that price.
Reply:Oh......... missed that part .... "tank". Priced those out lately?
Reply:If u don't buy it, you should post up the seller contact info, someone here that is close enough will definitely jump on itTiger Sales:  AHP Distributor    www.tigersalesco.comAHP200x; AHP 160ST; MM350P,  Spoolmatic 30A; Everlast PowerTig 185; Thermal Dynamics 60i plasma.  For Sale:  Cobra Mig 250 w/ Push-pull gun.  Lincoln Wirematic 250
Reply:thank you every one.i bought the machine. he did not give the hose and the flow meter thow. kind of mad but it was not listed in the add, that it came with it. so, i can not really get that mad.he gave me some cups and a bigger ground clamp.i took my brother with me. he welds with a syncrowave 250 everyday and he said it is in the same power spectrum as the 250 with possibly a little more power. the guy had too small of a ground cable and clamp hooked up and the wrong size cup and tungsten.the machine did 3/16 aluminum no problem and penetrated a little into a piece of 5/8 and 3/8 steel on the middle setting without adjusting anything else and too small of a ground cable, with wrong cup and tungsten. (pure argon).my brother has a 330 a/bp and he said the 320 reacts the same, and has the same type of power as the the 330 for the steel and aluminum he welded. as everyone said here the 330 will have more power for thicker stuff but most stuff that is welded will not be that thick. the 330 was designed to build ships. the 320 is more than enough to get just about any job done.oh, by the way. my brother does not like the syncrowave 250. it has nothing but problems, is always breaking, and is not reliable. they had the machine 1 week and one of the main circut boards went out. mulitple other things and now they were on the 3rd relay for something and finally just bypassed it so they could use the machine. he would rather use his 330 instead. when he needs to weld, thats what he wants to do, is weld. not have to fix the stupid thing just to make money. thats what is awsome with the old welders. they are just machines that where built to get the job done.got home about  12:15 AM. Nothing better than getting cool stuff at night time when most people are sleeping.  well, thanks again every one
Reply:Congrats. I know you'll be very happy with that machine and you picked it up dirt cheap. I know a couple of guys who would rather have older 330's than newer machines. My blacksmithing instructor being one of them.I'm a bit surprised at his poor luck with the Syncrowave however. The tech school has 10 Syncro 250's and very little trouble with them even though several are older units and the day kids can break just about anything..No government ever voluntarily reduces itself in size.

Reply:maybe they have a lemon?
Reply:You got a hulluva deal. You're going to enjoy it's performance once you get the settings down for the different metals. Not much to go wrong with them. Caps and relays are cheap compared to boards. Flow meters are out there reasonably priced. Look around and be patient.Pic's?
Reply:Originally Posted by DSWNot quite. Output wise, you would have roughly the same power available with both machines. Both are rated at 60% at 200 amps and top out at 300 amps roughly. However the 250DX has some advanced functions an older machine like that 320/330 will not have such as pulse. I'm not 100% sure about balance control on the 320/330 because I've only used one for DC tig. AC balance can help you get a bit more out of a machine. The range of balance adjustment on the Syncrowaves is about 68% DC neg in min cleaning and 55% DC poss. in max cleaning, vs say the traditional 50/50.
Reply:Sounds like a great deal.

Reply:here are some pics Attached Imageshere are a couple more. the bucket is the guys simple coolant tank. not what i was expecting but it works and it runs through the machine. it is a fish tank pump and it just gets plugged into a 115 wall outleti am going to make the cart wider because the machine barely fits on it and i want to build a large water tank that will sit next to the welder Attached Images
