matts37chev all welding types, should always be as clean as you can get it
practice with the new set up- adj. wire speed and temp up and down until you get a feel for where you are at and what works and doesnt

67Elcamino I finally got the gas going but for the first couple rounds Im not too impressed but Im starting to practice and getting better. heres a couple things I noticed and wondering if someone can help me ;
The chart on the welder recommends when using 75/25 Argon/Co2 between 20 and 30 CFH

Is CFH the same as SCHG that indicates on my regulator?
If Im using 84/14 mix do I use the same CFH pressure?

I noticed that when welding and go too fast the wellding bead would not penetrate if I wait too long to penetrate it burns through Seems like it works well with very clean metal but if its not really clean it does seem to burn deep enough and causing metal beads to just sit on top of the piece Im working on. Would it be true that using gas with .23 wire instead of flux core .30 wire requires the metal to be cleaner?

deadbodyman Flux core is great for heavy stuff it looks like a bead of chulk but it really sucks for sheetmetal.

MRTS33 I recently bought a Hpbart 187 welder and tried welding sheetmetal with .035 with flux core wire. That was frustrating burning through like it was to hot. Did some reading and switched to .030 flux core and was a lot better. I read pull the trigger only a couple of seconds and make good spot welds. I finally got to the point where I could make like 3e's in a row and moved on so as not to distort. Moving a little quicker helped not burning through. I am soon going to make the jump to gas and as said it will get easier to weld the thin stuff with better results.

very nice
let us know how that set up compares to the flux core wire
i will be very interested to hear what you think

100% cO2 is used for better penetration, so less cO2 might be better
did the welding shop recommend that mix?
or is that all they sell around there?

Just realized that I have to use a argon regulator and i dont believe the one I have is such. Do you have to use a specific Argon regulator?

DanielC If the regulator came with the welder, it should be OK. I understand there is a problem if you go higher on the CO2. It cools off more in the regulator, and freezes the regulator.

Maybe the lower percentage of CO2 is a California thing, to reduce the imagined global impact from CO2.

matts37chev i'm not sure what size (cu. ft.) mine is, but its 2ft. tall
i had the small one first, and it went empty kinda quick
so last time i got it filled (exchanged) i got the size i have now
if its too big (3-4 ft tall) its a pain to move around if you take you welder anywhere
12-09-2011 01:01 PM
DanielC My bottle is 43 CU/FT.
I brought my welder home August 10th.
I got a refilled bottle December 7th. Remember Pearl Harbor.

67Elcamino Picking up a 75/20 Argon/CO2 mix today.. What do you guys think?

20 cu in tank $95 full $36 refills

60 cu in tank $144 full $40 refills

Will a 20 cu tank go too fast?

DanielC Get the gas bottle, and practice. Here is my GMAC welder, A Miller Autoset 180.
.

Get the smaller wire, and a few extra tips. A pair of good diagonal cutting pliers, you want to cut the little ball or nub off the end of the wire, each time time you end a weld. also get some sheet metal, and cut it up into coupon or credit card sized pieces, and weld them together, as practice. It helps if you weld some thicker gauge metal before you try to weld auto body sheet metal.

If you have a Community College near to you, you might want to consider enrolling in a welding class. That would be good practice welding, with an expert being able to help you.

I live on a smaller farm, so there are other things to weld. Repairing field mowers, fixing wheel barrels, fabricating small items like water bucket holders. Things like that. all good practice.

Did I mention it is a good idea to practice?

deadbodyman OMG ,get some gas.welding without the gas is like painting without air pressure...
