what thickness mig wore should i use for:
-chassis
-body panels

i use 0.6 ihave used 0.8 with no probs

I use 0.6 for everything. I dont get on with 0.8 on vehicle stuff

But some say that 0.8 feeds through much better - with less slipping/jamming. I have always used 0.6 - and have had problems with it. I intend to try out the 0.8 when I next have any welding to do.

Using 0.6mm made me think that my Sip welder was as bad as a lot of people claim (mainly making frequent 'birds nests') - changing to 0.8 removed that problem altogether and I haven't used the thin stuff for years now. Wire feed mechanism in my new Sealey welder might handle it better, but I don't think I'll bother to find out!

I've struggled with 0.6 - the wire kept sticking in the pistol tip. I tried all manner of different settings, with no improvement. So I use 0.8 all the time now, and it hardly ever sticks in the tip.

Funny business, welding!

I've never investigated what the proper distance from tip to the end of the outer shroud is recommended as, but on my, gulp, SIP, the two were nearly level, and the wire was always sticking. I made a distance piece to bring the outer shroud forward by about 3mm, and cured that one! (Still plenty more problems with that particular make, though!)

I'd bought a new shroud, but the problem with 0.6 persisted.

I'd forgotten to say in an earlier post that the angle of the MIG pistol is very important for ease of welding. I'm still not sure exactly what the best angle is - I've been meaning to find out for years .

I have only ever used .6 wire and never had a birds nest in the welder, I am however an expert on welding the wire to the tip!
I have virtually cured this by increasing the distance to the work not allowing the wire to burn back to the tip.
I have the wire drive set so that if I did get a tip weld the drive would slip without a problem.

Get an SIP and it automatically does that, wanted or not

I use 0.6 and 0,8 in my sealy welder with no problems. if you find the wire is sticking back in the tip it is usualy because you are working in a bit too close. 0.6 is fine for chassis work but use a higher voltage and weld a bit slower to ensure good penetration.
