I'm going to start doing Hot Air soldering and I have been wanting to for a while and I just couldn't decide on witch cheapy unit to buy like a Baku because I heard something things about them and the other cheapies I didn't and I got a bit gun shy on pulling the trigger and just ordering one.

I was talking to a guy that has a small electronics shop he runs from his home where he also does a lot of repair and I told him I was looking to get into Hot Air for soldering SMD hobby kits because I do a lot of them in spare time and give them away to friends or as projects to do with kids I know.

When I called up the guy I know I told him what I needed to order then told him I was looking to get into Hot Air soldering very soon and he told me he ordered a Quick 861DW for a guy without taking any money down and got stuck with it when the guy did not come back to pick it up and he told me I could have for the 189.00 US funds it cost him so I sent him the money threw PayPal and I'm going to pick it up this later this week.

The guy I'm getting this from does very little Hot Air soldering and so he could not advise me on what kind of solder paste to buy,I'm only doing hobby kits for the most part and will use it for some repair work,I do not want to buy the most expensive solder paste on the market and have go bad before I even use a quarter of the syringe,I don't mind spending a few bucks for something better but I don't want to waste my money either.

Has anyone tried the Mechanic brand found on Banggood and ebay and if so what's it like,for me I would like a solder paste that flows ice and is easy to clean off but is not 30 to 40 bucks a tube,I like to use AIM wire solder and I pick it up when I'm in the city but I don't want to spend that much for a paste that is only good for a year that I may only use half of.

I have gotten some really good solder from China off ebay before that flows and wet's really nice and the joints are not a shiny as a product like AIM's but to me if your on a really tight budget that's a small pay off,I'm not some much on a tight budget it's more of a thing where I hate wasting something that you have to pay a premium for.

I got some of this. 

MG Chemicals 4860P 63/37 No Clean, Leaded Solder

A little will go a long way, but the paste will go bad as the flux breaks down (or whatever it does)

No clean is actually hard to clean up, but you don't have to.  Dirty boards look like crap though.

What do you use to clean up the MG Chemicals stuff.

Be careful, as $189 for a Quick 861DW sounds really fishy to me (there are some clones out there being sold as 861DW's; example). The cheapest I've seen a genuine unit go for lately is $265, and a real one wouldn't be that hard to sell at a fair price.

As per solder paste, leaded or lead-free?

For example, you could could get MG Chemicals 4860P-35G (63/37 tin-lead, 35g, no-clean). Most will be no-clean, but some of these use modified rosin, which is easier to clean than the synthetic resin based variants. So check the datasheets. Kester's EP256 (also 63/37) is one such example. CML Supply breaks it down and sells in hobbyist/small repair shop friendly sizes (syringe & jar). Indium offers 63/37 that uses RMA flux in a 4oz. jar, 10ml or 30ml syringes, as does AIM's RMA258-15R (10ml syringe & 500g jar).

As a general rule, stick with well known brands such as MG Chemicals, AIM, Indium, and Chip Quik (these offer 10ml syringes). Kester and AIM for example only sell in large sizes meant for production (i.e. cartridges).

There is one thing I forgot to mention about this deal and I can see by me leaving it out it may sound fishy.

I have known this guy for a long time and I only go to his shop 2 to 3 times a year at the most and he mails stuff to me but I never knew he had a access to the Quick line of products.
When I was deciding whether to buy purchase a Hot Air set up and I read so many bad things about the Baku that you either got a good one or you did not I seen a smaller Quick Hot Air station and I was considering I forget the model number but anyway I was planning on buying something and just hadn't gotten it nailed down.

I called Quick USA about the smaller model and asked if they had any dealers in Canada and they said they do not have any official dealers in Canada but they a few people who buy their stuff to resell and they mentioned the guy I know who is more of a repair shop but will sell to people if they can't find what they are looking for.

When I talked to the guy I know who had the Quick 861DW he told me he was selling it to me at cost because he told me that he would never sell and does not get anyone asking for a bigger machine like the 861DW he also took a screen shot for of his PayPal screen showing me what he paid because I had asked him if it came from Quick because I did not want to buy a fake,plus I confirmed it with Quick that they sold him a 861DW and they said he normally orders the smaller unit if someone wants Hot Air and this was the first one he ordered.

The only reason why I asked him if he got it from Quick or not was not because I don't trust him I don't trust the people that may have sold to him and saying they are a Quick dealer when they are not.,the guy I deal with is a pretty stand up guy and deals with people when certain things are not always fair and try to a middle ground rather then saying tuff crap that's the way it is.
