Mig power and feed settings

[smokey9701]

I have a Hobart 130. It has a chart which provide setting for different thickness and for the type of wire. I have an ArCO2 bottle. I have noticed that when I use the recommended settings, the feed rate is too and and the wire start to pile up in the puddle. So I adjust it down and then things work out.

Here is one I don't quite know how to adjust for. Lets say I have 1/4 inches thick piece of steel angel and I want to weld an 1/8 inch piece of flat stock to it. Is there a rule of thumb on how to adjust voltage and wire feed when I have a difference in the thickness of stock? Is it just a matter of trial and error on some scrap to figure it out?

The door charts just get you close, you are right to adjust as needed.

For thick to thin, set for the thicker piece, then hold more arc/bead on the thicker piece.

Well, that is kind of what I have been doing so I guess I have been on the right track.

Thanks for the information.

That is a wide open machine for that type of joint.

utube TimWelds perfect mig welder
settings in 3 asy steps

using an everlast cyclone mig....has power set feature

shows bunch of metal thickness on screen...usually weld 1/8...gives 19 260

a few minor problems with this everlast....

I like the mig torch, swivel thingy bottom handle, very comfortable to use...

No digital display on a Hobart 120Volt model 130. Amp settings are 1 2 3 4 5 and that's it. Wire feed is variable. It works for light jobs. At the time I got it, I only had access to 120 single phase. I now have a shop with 220V so it may be time to move up. But, it does work for the jobs I need to do and I have yet to have it cut out due to duty cycle overload.
