    Recently replaced a plasma cutter that I had sold years ago with the tiny one branded as Reboot for $200.00 Canadian.

    The unit is dual voltage, I'm running on 220 volts for the air supply a 5hp compressor on 80 gallon tank but most smaller compressors will handle the demand if your patient.

    Types of metals I tried it out on, Copeland refrigeration compressor case - cast iron, aluminum truck rim, stainless steel steam table, propane tank and some junk iron. Great fir zapping through bundles of insulated copper wire.



    I have several large starters with my first plasma I would blow out the screws securing the steel shoe that holds the field coils in place to recover the copper coils. This plasma struggles at this chore, not large enough for gouging.

    The propane tank had some fuel in it, the fuel ignited once the tank had been pierced and burnt externally. Cutting with plasma versus an oxy torch is that it injects an excess of oxygen - BOOM. Plasma is a safer method as it does not use oxygen to cut metals.

    Mike1 I highly recommend using one of these small 60 amp plasma cutters for the task your faced with, it'll handle screws, copper lines, wires and cutting tanks. be the best money you ever spent on a tool.

    And remember what I said, plasma does not use oxygen, so there will be minimal reaction with any oil remaining inside the compressor when cutting one open.

    Cutting sealed units with a sawzall? now thats determination.

    I know you dont have alot of room, but i would save up the Units, coils, copper and maybe even the motors and try to get bulk pricing on them. Most yards will pay around .05 to .10/lb more with alot of volume or 200+ lbs. Maybe not the S units cause they are heavy to begin with, might need 1000 lbs for those. Got to talk to the yard manager about that tho. My yards mgr is an awesome dude, i dont have to call the yard, i can call or text him personally. Currently the markets are not to stable at the moment. but thats how i would do it

    greytruck specks truth, yards will up the price on the volume of weight going across the scale.

    Mike1 I no longer think the boss lady is a Karen, you may never see those AC's being gifted to you.

    One thing i learned from scrapping for about 15yrs is the whole dont count the chickens b4 they hatch.

    ive had so many people (residential) tell me that they are going to have this and that so many times, i dont even believe people anymore. Its now or never how i do it now-a-days with the general public flagging me down or talking to me at a stop light. Pretty much the main reason i only try to deal with the trades shops. They generate the scrap, they want it gone that day, and im ganna go get it. Even if they dont want to haul it back to the shop, they know ill come to the job site and get it if its permitted.

    greytruck you obviously know all the old sayings which are disguised as lessons, I'm often guilty of counting my chickens before they hatch and get caught in price drops.

    The phrase "tomorrow never comes" is often used to express the idea that the future is uncertain and that we should not rely on the assumption that something will definitely happen or be available in the future.

    You learn a lot of phycology, working with the one of folks sucks, if they do not agree to my schedule then they find someone else.

    If you miss the first buss don't break into a sweat because another one will show up shortly.

    I bet the boss woman didn't set the terms when the guy came to evacuate those systems as she would have incurred multiple service call charges.

    For reasons unknown to me, I think Mike1 missed the boat on this deal.

    Seems we are missing half the story here.

    Why did she say you cant take them?

    Were all these units part of a contract to be removed and then properly disposed of?

    Is the company planning to scrap them their self's or do they have a guy thats going to pay for them, or planning to auction them?

    Are they going to be resold?

    I also agree with Alloy that the units have not been drained. I never heard of window units having the refrigerant removed from them.

    I concur. We don't have the whole story.

    I think different parts of the country have different customs.

    The states here in the Northeast are pretty serious about environmental issues. Removing the refrigerant from Freon appliances like window ac's, refrigerators,freezers, and dehumidifiers has been standard practice for quite awhile now. It's just what you do at end of life before shipping them off to the scrap yard to be recycled.

    Maybe they do things differently where Mike is.

    I believe the EPA and OSHA have no state boundary's when it comes to enforcing regulations. Many rulings / cases end up with SCOTUS the highest court on the land.

    There are different levels of government alloy. They all have their areas of responsibility and respective roles to play. It's best if all the different levels try to work together for the purpose of serving the people. It's also important that the different levels stay out of each other's way.

    At the end of the day .... it involves some complicated ideas about where power should rightly reside and the preservation of democracy. Federal law doesn't necessarily reflect the will of the people of a given state or region of the country.

    Most states have an Environmental Protection Agency called the Department of Environmental Protection. Acronyms federal EPA and state DEP respectively. Enforcement of the environmental laws seems to happen more at the state and local level in my experience. That's the way it should be as it more accurately reflects the will of the people in that state or municipality.

    Most environmental problems that come up can be handled at the local or state level. It's a relatively rare thing for the the full force and power of the U.S. Federal government to be called in to handle a situation. Big things are apt to start happening when those guys roll into town.

    You would be surprised though. Most of the time it's less about law enforcement and more about lending the financial support that will be needed to address a problem that has come up. That comes in the form of grants and loans that will be needed to tackle a project. It's a positive thing and not a negative thing. More carrot and less stick.

    My apologies Mike. This thread should rightfully be about you and processing window AC's. I just wanted to take a moment to explain to alloy why his picture as a Canadian citizen isn't an accurate reflection of the reality on the ground here in the United States. At least not here in the State of Maine.

    The situation might be different for greytruck. It could be that the DEP in his state is a bit more laid back about the laws and such. It would depend on the will of the people and the state legislature where he is.

    It's all good !

    No prob she said it's not the acs that is the problem it's all the way in the back the truck driver is going to have to move them up so she knows where it's at so if someone gets hurt say one falls on top of me lol not likely I've been doing it a long time haha. She's fine with me taking acs now. I can even get more after the 160 lol. As long as they don't work.

    That's good news. I'm glad you were able to get things cleared up.

    I had a little time a few days ago so i tore one of the ac fan motors apart to see how much copper was in it. It was about 1/3 of a pound. It's really up to you to decide if you want to break them down or sell them whole.

    grey truck has a sealed unit scrapping video up on youtube. It's one of the best ones i've seen. It might be worth a watch if you are looking at doing 160 of them. Don't know about you but i'm always looking for different ways of doing the job. Once in awhile you hit on something that makes the job go easier.

    Thanks I'll watch that. I was wondering what a power cord on a window ac weight is if it's worth stripping them ?. If a u haul has a weight limit of 2,850lb how many window ac units should i be able to put in it on one go ? I was thinking 25 ? If each one weighs 80lbs I'm estimating on that since they are not all the same.

    The boss I work for is cool he's awesome she is the boss of him I think she is road blocking me giving me hurtles to jump through. She knows this scrap is money I need to pay off a debt she doesn't know how much there worth I know this cause she was like are the ac units going to pay for a u haul truck haha. This is going to be almost two months of my pay I only get little over 1k bi weekly net I had to drop medical,dental,eye and 401k payments to keep as much money as a can without getting a second job to pay for stuff.18.54 a hr ia not enough in this economy plus no overtime. To answer alloys question she said she didn't ask the right questions when she said yes and yes if I got hurt on site her head would be on the chopping block. I usually don't go to bed til midnight anyways always been a night owl somehow ended up with a day job haha. So 3hrs after work shouldn't burn me to bad. Yes they drain them how else would HVAC people scrap them if they didn't ? Do they go and snip window ac lines in their shops I wouldn't think so it would be a contradiction for all the school they had to go through and thsy could lose there licences for that. Safe to say I get along better with my boss he is more laid back. If all goes well I should have some this Friday I'll keep you updated.

    I'm an old fart. Anything over 40 lbs makes my back and knees ache the next day.

    Most of the window ac's i've got coming in these days are fairly comfortable to lift. They're mostly plastic and styrofoam with a steel sheet metal shell and solid steel bottom. Most of the weight seems to be in the sealed unit. I doubt most window ac's are over 40 lbs these days. They're not that hard for this old codger to manage.

    The window ac's are built to operate on a 110 volt / 15 amp circuit. They don't seem to be any more than what you would get with a 12 ga extension cord. It's stranded wire inside so it would be a hassle to strip. The plug ends are way oversized with a circuit breaker built in. Probably best to cut the plug ends off and sell the cord as ICW. About he same grade as any other cord that plugs into a wall outlet.

    Hard telling on the U-haul. They rent different sized trucks. Most of the trucks and trailers they rent are a little overbuilt cause they know their customers tend to overload them sometimes.

    YMMV ... it's all just based on most of what i see coming in on a regular basis. The really old ac's would weigh more because they were built with more metal and less plastic back in the day.

    �� A old fart huh how old is that?. So the ones from the 90s are more weight. There are lots of different ones some have one bracket on top and some have two brackets on top the ones with two brackets are the heavier ones the ones with the single brackets on top are easier for me to lift. If I was able to send pics I would haha.

    I'm in my mid sixties Mike. At this age ... it's better to have some kind of boss job and leave the heavy lugging & tugging work to the younger hands. Work with your head / not with your back.

    The AC's from the 90's would definitely be heavier. I went to buy a new ac from Home Depot awhile back and couldn't believe how light it was in comparison to the one it was replacing. It seems to have held up well enough even though it's not built as heavy.

    The few older ac's i've torn down seemed to be more difficult to scrap out. Some of the sheet metal screw heads were all rusted up. The teardown procedure varies some from manufacturer to manufacturer. The good part is that you're likely to get a little more copper out of them. They were built more heavy duty and made to last back in the day.

    Nowadays they're built as cheaply as possible.
