mig wire size

[EK JAY]

im about to replace a floor pan in the ek wagon and wondering
would .9 mig wire be better to use then .8
we use .9 at work but we use alot thicker gauge metal then
the floor pan im putting in any info is good

[muza]

Thats what i'm using with gas mate.
Seems to be doing the trick
Be interested on others with more experience with thin gauge steels thoughts though
Cheers Muza

Thanks muza My mig at home is a gassless 155 amp
works fine with the .8 flux cored wire
on the panel's but wondered if i should step
up and use .9 on the floor

[RobinGi]

I've replaced 3 floor pans using .9 and all the settings on the mig set to min
Blew a few holes here and there sepically where the butts didn't line up but in most part it went quite well
Cut up the sections that your've removed so you can get some practice welding them back together before moving onto the real thing

You would be better off with .6 for panel steel or a floorpan.

point 6
NOT GASLESS

[Mick Jagger]

gasless wire is banned every where ,but not here
bad for you
its like CCA pine in playgrounds ...........WHAT THE FKUDK

I haven't got to panels yet but would .9 be too much heat, causing it to warp?
Cheers Muza

That is definitely a major factor.
its about not having to heat the wire as much to melt it,you have more control over the fine tuning of amps/heat and wire feed with .6 om light gauge metal.
Id be using .9 on anything over 1.6,though.
That said,.6 wire could weld 1.6 withput problems.

And like Jase,I never use gasless.
I reckon its messy and expensive with an inferior weld.I didnt know about the health aspect.

[muza]

Cheers for that wot.
I'm only new to welding thin gauge metal so your help is appreciated.
I have a Lincoln 180c welder with gas. Like you say I personally wouldn't use gasless either. I'm finding even with the settings right down low it probably is still a bit hot, but still ver usable on the 'hidden' stuff. Don't think i'll try my luck with it on panels though!
I find if I'm doing a longish run it'll blow through
I might get some .6 and see how I go.
Cheers for your help.

I replaced a sill and floor pan recently using .6 and gas, went very well.
I've got a Trans-MIG 165 which is awesome, you can run very low heat. (I practiced on .5 steel before doing panels)

[Mick Jagger]

when i weld panels its not much more than a tack every inch ,a good tack though,and go
over and back again and again,easy on the heat...
and a wet rag to keep it kool ,im probably doing it wrong
but the distortion of a nice door is worse,just practice on a FB
or a EK

[muza]

Yey I've heard of the wet rag thing.
Do you just cool it straight down once you've tacked it?
Might see if I can get hold of an EK door...............don't wanna wreck an FB one

If you change wire size do you need to change anything else as well? eg tip size

[wot179]

Yep,youll need to change tip size as well,but they are cheep so buy a bag of em,you are gunna want a new one before you know it anyway.
