hi folks I am going to work with some 10 gauge 304 ssI have a miller 35 mig & a friend of mine gave me a 30#spool of #309ss wire the only problem is that its .45 dia. will it work in my millermatic 35
thanks Larry 4

Hey there larry,

According to the MM35 manual the Wire capability is .023 .030 and .035

but has anyone ever tried the .45 " in a 35 or simular machine

[Broccoli1]

I know that's what you're after and hopefully someone will come along and have an answer for ya

but has anyone ever tried the .45 " in a 35 or simular machine

I cannot find a drive roll for that machine in .045, so my guess is that it's a no-go.

Drive roll not big enough, but also there's the liner/tip questions, plus will a 30# rool even fit in that machine?? Probably cheaper to just get a small roll in the proper size.

[larry4]

I allready tried the roll on the machine & it fits & runs threw the .35 liner but I did not have any tips

[wworks]

if it runs through the drive roll and the liner, then if you have a regular .030 or .035 contact tip, you can put it in a drillpress and drill it out with the smallest drill bit you have
(i ususally use a 1/16). make sure to drill very very slowly and clamp very tight because its easy for the copper to get stuck on the bit so go slow

[Mike W]

You should be able to drill out a smaller tip.

larry4,

This may be an exercise in futility! I do not know if that machine is going to be happy running .045 stainless, since it is not rated for .045 wire of any type. \

Stainless typicaly requires a higher voltage at the same wire feed speeds that you would use for MS. I'm not sure the machine has that much arc voltage under load.

That is a lot more wire for the machine to melt. Remember, the cross sectional area increases with the square of the radius, so small incrieases in diameter add up fast in total volume of wire. Also would be a whole lot stiffer for it to push through the whip. Especially in stainless, which is stiffer metal to start with.

You get an A+ for determination ...
If you make this work ....they should have you go and Fix New Orleans

[larry4]

thanks for all the input ,tomorrow I will pick up some .45 tips & give it a try if everything in life was easy anyone could do it

It's not so much a matter of easy, but correct and possible. The 309 would be the wrong filler for 304,(308 is correct), and IF you're using standard steel gas, that too would be wrong. Now if it's just a matter of sticking the pieces together, without regard for strength or corrosion resistance, then go for it. Depends on what yer welding. You could also just weld it with regular steel and c-25, as I'm sure has been done many times before.

[larry4]

I do consider myself a craftsman & want to do it the right way would you please explain to me the differances in the filler rods & there #s &i am going to use a tri mixture that my supplier recommends & what i am building is a dump body for a Dodge 3500 4X4 diesel that I restored ,this is the second body that I have built the first one was with reg steel which has to be sandblasted & painted often since we plow here in Ma. SS material cost about 3times the amount but I think well worth it. The reason I am interested in this wire is that a friend of mine has 5 30 lb. rolls that he wants $25. each for & since I am from New England I am very frugal (cheap) thats my story .
