Haven't seen the specs of that cigweld but I'm picking it will be DC only so no ali welding.
When buying chinese, they are not all created equal, even though they all look very similar. Basically I think the old rule 'you get what you pay for' still applies.
I did a bit of research and ending up buying a Jasic 200A AC/DC which retails in NZ for NZ$2500-3000. It is nice to use, but has broken down three times. And that's supposed to be a good one. the repair shop said they are pretty reliable and told me the unit BOC used to sell was the same welder rebadged. Also Excel-arc, same welder. I don't use it everyday or anything but have given it a pretty hard work out on several occasions.(ie in a commercial setting, handpiece getting so hot you can't hang onto it even with good leather gloves)
Yes it has broken down but including repairs it would still work out way cheaper than an equivalent Kemppi, Fronius, Miller, Lincoln or whatever. I would love to have a nice Kemppi don't get me wrong but on my budget at the time it was chinese or nothing, and I'm quite happy with it.
Mig welding alloy is ok, but it brings it's own issues which you don't get around without spending big money on the right machine either.
