Whats your welding Like?
I have a small inverter stick welder and my neighbour who has not welded, picked it up easy.
I prefer migs with gas ,mine is 15 amp (250) and probably overkill unless you weld a lot.
Lincoln Electric has a good name

If you can weld with Stick you will find Mig easy, Once you get the hang of it.specially if you go Gas.
They would be the most forgiving welder you can get.
The Gas shield makes them awesome, the gasless is So So in my opinion

I have a little inverter that is Awsome for onsite jobs. It's the size of a women's hand bag and goes all day.
I also have a SIP migmate that I used in the Worksop to manufacture heavy barred doors for Dept of housing buildings in Redfern. Mig is better as suggested but requires gas and is heavy.

If I'm only welding T sections Id get a good quality inverter. They are not like the old Big W CIG jobbies that are heavy and suffer chronic wand stick. They amp up when you strike. A good auto shield is also a good investment .

The SIP migmate 150N is for sale BTW, I've no use for it anymore.
If trees screamed when we cut them down, We wouldn't. If they screamed all the time we would.

I've got a baby MIG, I use it without gas and it's good. The Helmet with auto darkening glass is a godsend!!!

I believe if Portability is not an Issue, I would prefer the Mig with Gas.
Mind you that Mig looks reasonably Portable

If you're doing structural, and trying to get a decent penetration into 4mm & 10mm sections, then you need a lot of grunt.
A household/handyman MIG won't be up to the task, nor will anything single phase.

For that sort of work you're best off with a decent stick welder - for the money you'll get a better bite.

But if you want an all-round welder, you cannot go past a MIG. It will do sheet-metal a whole lot easier, without blowing holes like a stick, so you can cover a wider range of future jobs.

I have a 15A single phase MIG I bought 2nd hand some 25 years ago. It's an old CIGweld job that weighs a tonne, and takes the large bottles you have to rent (but I have adapted it for the disposables). It's great for doing panel work on cars, and I made my first roti ring with it, but it struggles to penetrate enough when doing something heavy (like a gearbox cross-member from 4mm angle.

+1 for the SIP 150N - they are a great unit, and one of the easiest to learn for a beginner, while still having all the needs/wants for an experienced welder.
I "upgraded" to it about 15 years ago, and it's much more forgiving than they old CIG. Sadly mine was destroyed when it was on loan to a mate, who didn't think about where his welding sparks were landing, and promptly burnt down half his garage when rags in the rubbish bin caught fire - rags that had been used merely 10 minutes earlier to wipe up spilled paint, and were soaked with paint, and some with thinners, so it went up real quick.

ok, here is my 2c


Stick - cheap entry cost and quite versatile (lots of different sticks you can buy to weld different metals or even one type of metal to another)
Mig Gasless - Cheap entry cost mig but higher running cost due to flux core required to make a mini atmosphere for welding. the Gasless mig is required in some cases for outdoor use as Gas Mig has issues in windy areas (outside). the slag can be a pain though and you will need to wirebrush a lot to re-start a weld. not able to use small wire for thin metal (such as 44gal drum)
Mig Gas - Very clean welds with no slag or spatter.Wire is less expensive.Wire size down to 0.023: (0.6mm), great for thin metal.
Tig - Very Pretty welds but takes a lot of practice and hands/eye/foot dexterity

I have a cheapie gasless mig at home and i get by but would suggest a Gas Mig if you plan on doing a professional job

Anti spatter works well, Keep your sticks dry,
They can be dried out in a preheated oven door open.
Especially if they have been hanging around for a while or your in a Humid enviroment
