What mig welder?

[monkeymoreton]

For that sort of thickness a arc welder would be a great choice

unless you've got 3 phase, your going to be limited to around 220-230A max, even with a 32A socket, and unless your going to use it every day dont waste your money on something that large, look at around 185-195 ish as your limit, and if you want to weld thicker than they can cope with, look at MMA machines (stick) as an alternate. good machines can be sourced from R-Tech, SIP, Weldtech, and a few others

I regularly use a tecarc 181 mig and its a good machine for the budget, not sure what the prices are like now though. The arc is not as consistent as the murex that I use from time to time but it is still a very capable machine .

If you want to double your budget the 200a esab migs are just over a grand and that is a hell of a lot of welder for the money

My brother has a garage and uses a snap on tools ( cebora ) mig 140 , says it's good .

In the field I used a stick welder for agricultural stuff so am only used to MIG for steel sheet up to 3mm. In fact the little 162A parwelld inverter was good down to 2mm using rods.

 

Given that I'd plump for a MIG welder inverter and one with 4 drive wheels.

 

I notice Parweld also do an all in one MIG, Tig and stick welder for under a grand.

 

With the cost of keeping oxy-acetylene being so high I wonder if it would be worth having TIG for sheet work but have never used it. It would mean keeping a bottle of pure argon for MIG and TIG but there are a number of firms offering gas sales with no rental charges.

6mm is optimistic for your 150 amp welder, 4mm is more realistic. You will stick it together but not efficiently. For 8 to 10mm you are looking at something bigger than you will run on single phase mig but if you go for a mig/mma multiprocess welder you will do the job. You might have to up your budget a bit though.

Yes im not happy with the welding of 6mm most of the welding is 4mm, but cant find a reliable fabricator so going to start sorting it out myself

I've got the 250a R-Tech mig unit. I'm only a hobby user but my neighbour is a welder/fabricator by trade and has had a go with it. He really likes the way it performs.

 

Apparently their backup is pretty good too which is nice to know. I'd certainly recommend them based on my experience.

I recently had to buy a new welder for tacking up a small shed extension i was building of a genny.

I bought a new type Stealth arc welder, (sort of digital display) think it is an inverter welder, absolutely brilliant far better than my old arc and is so smooth to weld with esp on really low amp's with finer electrodes. Very very impressed with it

 

Even my old mig wouldn't weld of the genny (5kw) and this 1 does get a fair bit of penetration even on the thicker metals easily.

 

If ur not doing a massive ammount and esp if on thicker metals that are going to be worked/abused i'd just go with the arc welder, even the slag seems to come of easier with the new welder (possibly as easier to adjust to the correct ampage, old 1 was a dail and i never really knew wot ampage i was welding with)

 

Plus with ur costs of gas hire etc or needing clean metal and indoors/no breeze the arc certainly has a lot of benefits for heavier outdoor use
