Wire size

[Graham Brown]

I have a Hobart chart that says when using Flux core wire and welding material 1/4 to 3/8 inch it recommends using .045 wire. I understand the ironman 210 will not use wire over .035. Will .035 wire work well on 3/8 material?

[Zrexxer]

I understand the ironman 210 will not use wire over .035.

That's incorrect. See pages 22 and 23 of your owner's manual.

solid .030 will work well also on 3/8 plate...Bob

Zrexxer, I don't have an owners manual, but lookig it up on the internete shows that the Ironman 210 only used .023, .030 and .035 wire.

Oh, but you DO have a manual, you just haven't read it. It's right at the top of the page, available for free:



Anyway, like I was saying, page 22:

I stand corrected, but if you put ironman 210 in your browser and look at the specification sheet it only shows ;023 , .o30 and .035 wire

IM210 & .045 wire

To run the .045 flux core wire you would need to purchase the optional feedroll, gun liner and tips.

I would certainly consider how much work I needed to do in this range before I went to the effort to swap all the stuff, there are ways around it for a few misc pieces.

I have welded a lot of 1/4 inch steel,some 3/8 and even some 1/2 steel with
.035 flux-core wire without any problems.I am sure on thicker than 1/4 inch .045 would be better but if you burn it in right,clean then make another pass or two you wont have any issues with the .035 wire.Material prep and skill level will be the only issue.You have a good machine,just practice ,practice ,practice with it.I only use .035flux-core in my mig machine and feeder.It can do 16 gauge up to 1/2 plate with proper prep.Skill level is the main thing.And that will come over time.

Do you understand why this is recommended?

[Graham Brown]

probably because it will run better on .045

[Graham Brown]

boilerman, are you telling me that you can't weld 1/4 inch with ,o35 on a single pass?

[boilerman79]

NO, not at all,you can weld 1/4 steel with a single pass of .035 wire.As long as you have enough machine to do it.If you have a 210 you have enough machine.In some cases a single pass on 3/8 will be all you need .it just depends on what you are working on.If I am making a stand to hold a bench grinder and am using 3/8 steel ,1 pass is all I need.If I am building a ramp tp load a tractor then I will use 2,3,4 passes ,what ever I think it takes to get the job done.This is where experience comes in.The key is to burn it in right every time,clean after each pass.
If you are going to weld 3/8 thru 1/2 steel day after day,then you need to get everything you need to switch over to .045 wire,but if you are only going to weld that thickness every now and then ,.035 flux-core will be fine with the 210 machine.Just think about what you are building and makes as many passes as you need to get the job done.
Make sure your wire is for multi-pass welds,as some flux-core wire says single pass only.I dont know the designation numbers off the top of my head,but I can find them if you need them or I am sure someone here knows them .

boilerman, Thanks for going into detail. I am old and a little bit thick headed but I think I understand.
