Hobart Handler 180: Settings for Sheet Quarter Welding?

[63nova9sec]

Hi Guys. Havent stopped by in a while. I have to do quarter patch panel replacement. I have it all clamped up with the sheet clamps, leaving about a 1/16" gap all around.

I have had some burn through, on the lowest setting, 1. I would like to know if I should speed up or slow down the wire feed? It seems to always like the 50-65 range for almost everything else I did, but everything else was thicker also...

Im pretty sure Im using .030 wire, but not 100% since the label is gone.

Last question is, where can i buy some of those backing plates, besides eastwood co, that are copper magnetic? seems like there the monopoly... I will ask this one in the tools area as well.

Thanks!

I'm no pro here but for sheet metal I think I would go for less or no gap on my fit up, that is, if you can.

I would also think that if you are burning thru, then faster travel would help. Are you working on this in place or on the bench?

Just a thought from a nobody.

Good Luck.

i use 023 and no gap and just keep tacking in different places so not to warp as far as settings 1/30 area but my steel on the jeep is a little thin but it works, c25 for gas hh187

Hi Tom, yes working on this on a vertical part of the quarter panel.

Thanks CBorema! I will try lowering my wire speed a lot. I never even thought of dropping it to 30, but i will try. im pretty sure the hh187 is just a newer version of the hh180... should be similar settings.

for a backing plate all I did was go down to lowes and get about 2 foot of 2" copper tubing and flatten it out. works great!

.023 solid wire and C-25 shielding gas is the best way to have the unit set up for thin ga sheet metal. .023 wire will allow you to dial in the unit about 10 amps lower then an .030; which, should help reduce your chances of burn through.
