Welding???
Boggert:
I am self taught, but it was a case of trial and error! I got there eventually, I had a SIP mig welder, now sold as I have not used it in years. I agree get a 130-150 MIG Gas and get a larger bottle.
Oh yes get a good grinder as well! :lol:
rollazuki:
OK, dont buy gasless!
Ill expand.
They weld hotter, so harder to do thin stuff.
They smell and smoke, Yeuch.
They leave slag and need cleaning.
They are harder to see the weld 'pool' and so harder to judge penetration(oooer)
You cant turn the gas pressure up to weld outside on a windy day.
The wire is more expensive.
Just my opinions thats all :wink:
clbarclay:
welding land rover chassis you can get away with a smaller welder as you tend to only weld bits ata time, however bear in mid that just because a welder can run at 90 amps maximum it can't do this for very long peroids of time or it will over heat, its to do with the duty cycle of the welder. 130 to 150 amps should weld 2 to 3mm well without over heating issues.
For cheap welders clarke have one of the best reputaion amoung kit car builders. I have a draper 2300 which is pretty much as big as you can go on 240volts (its on a 32 amp plug). Its not too often I use it at full power, but doing things like making the rear bumper and welding up damper mounts made from 6mm plate then I need all the current its got.

Not if you turn the amperage down
The whole idea of them been gasless is so that you can weld outside on a windy day as there's no gas to blow away
For the amount of wire the average diy'er is gonna use it'll probably work out the same as the cost of buying the gas+wire for a standard mig.
Highlander1:
If you decide that you would like to do a simple mod or beef up the underbody protection aor build a trailer your'd be better to start with 150 min co's you will soon want to get more adventurous. I just built a new boat trailer and now built a trials bike trailer from thick steel.
Wee welders cut out when getting flogged with heavy steel.
I've been welding for 24 years now with both oxy acet and mig.
