Reply With QuoteI've no doubt you will find that to be a really good unit. It looks like it is specced up well for home use. Our 6 MIGs are going all of the time and our 2 oldest machines are Unimig. For home welding that will be more than enough.

SupporterI'm looking to buy a cheap mig welder to fabricate some stuff from square hollow tube. I don't want an expensive one as I've got a very good stick welder for heavier stuff. I'm looking at this . Does anyone here have experience with these or recommendations for something else in the price range, or advice generally. Thanks.
Don.

SubscriberUse an 80/20 or whatever MIG gas blend your local supplier does. Corgas do bottles with no rent - just a one off deposit - doesn't matter how long you have the bottle.Originally Posted by Don 130
When I click on the link, it goes to the home page of Unimig - what model are you looking at?
Whatever you buy, make sure you can get spares for it - tips, shields, rollers, liners, etc. Parts for some cheaper machines are non existent but I doubt that is the case with a Unimig machine, but worth checking.
If you need to contact me please email homestarrunnerau@gmail.com - thanks - Gav.

SubscriberC02 up to say 5%
Oxygen up to approx 3%
Balance argon should do it.
BOC's Argoshield light
Coregas 5/2
Air liquide Arcal 5
CO2 gives weld penetration, oxygen assists with weld finish / bead profile, argon is the shielding part. So choosse your poison.

Nice price.
I use an old CIG stick welder for mild steel and cast (yes I can weld cast.......without all the BS on the net and the right rods).
I'm interested in something like this Unimig for welding thin stainless.
Comments invited from all you erudite gents please!
cheers, DL

SubscriberI've never had to weld cast iron, but hear there is a bit of an art (Black magic?) to it...
So what was your chosen method?
High nickel castcraft rods, or something more run of the mill with plenty of prep, pre heat, cool down and peening?

Outline thin stainless a little more.
I have MIG stainless but you will need specific tri mix gas not really suited to mild steel plus pretty Exe spools of wire.
For heavy stainless I stick weld
Light stainless I scratch start TIG with straight argon (which I already have for al and Si bronze)
Also have bottle of argoshield light for carbon steel
For truly thin stainless where you are running 20 A or so TIG might be a better choice? Unless you be welding miles of sheet
