wire size question?

[txargyll]

my migs feeder wheel has two options 0.8 and 0.9, and im out of wire.

Question: can someone explain the benefits over one and other.

my welders lowest is 55A, which is not great for the thin suff, will 0.8 aid me in welding thinner metal or?

0.9 is fluxed wire, sure your looking straight and its not 0.6? coz 0.6 will help with thinner metal,

 

[txargyll]

sorry should have said, the welder in this case is a flux no gas welder

 

[normspanners]

Havnt seen any fluxed wire wire smaller that 0.9 ,sounds like it could be dual no gas /gas, 0.8 is a bit big for thin stuff on gas, if you can go gas try 0.6 but you will need a new drive roller.

didnt know that BUT £69.99 !!!!!!!!!f/kinel!!!!!!! bet they dont sell much of that, cant see 0.1 making that much diff.
i havnt done a lot of gasless i dont like the spatter

i pay around £30 inc vat for a 15kg roll of copper coated mild steel .8 wire, £70 is a joke, shop around online mate you will definatley find it cheaper...

dont worry it was just an example to show its availability, welder takes the small rolls at 5 quid each.
not sure if it could take the weight of a large roll, no manual so cant tell if the ferm 100 is capable or not.

55A is way OTT for thin (car bodywork) welding, so unless you expect to do a lot of thicker welding you've got the wrong machine. With a lot of practice it may be doable, but it will never be ideal. Doubtless someone will come along in a few minutes and claim he can weld cars with a minimum current of 100A, but it's certainly not for the newbie trying to learn MIG welding. It's like trying to split a matchstick lengthways with a tree felling axe. Some people can, but most can't.

i want to make a welder table 3mm stuff and am sticking anything to anything at moment lol, just practicing, i made a wine rack from horse shoes so far with it. i want to make a kids motorcycle trailer type thing that attaches to the tow bar which will be 3 and 2mm square tube. Owning a land rover i will need to do some welding sooner or later, i have tried using the welder with 1mm but and it works but i have to travel fast. if i have to do panels ill borrow my mates clark 85 that i just fixed as it goes down to 27A
