Before you grind it turn the heat up on the welder and make a fusion pass on the back side . The first pass you made on the top will allow you to get a nice flat weld without burning through . Look on the back side . With low heat you most likely did not get full penetration and weld will crack . I sometimes do this on purpose with but welds on thin stock . Do a cold build up on one side then come back and do a hotter pass to get full penetration without blowing through . If I had a Tig , I would do it differently . A tig is just a lottery win away.Eugen wrote: ↑Tue Jan 31, 2023 11:39 pm Small step ahead. After drilling the 3/4" pins on the bucket linkages new roll pins were installed.
Then it took me a while to find a piece of sheet metal the same thickness as the hood and cutting the missing piece out of it.

Set the flux core welder to low current and there it stuck.

There will be angle grinder in its future.

Re: Case 644 loader repairs
Haha Dave, nothing goes past you does it? I love it how you see right to the crux of the matter. Indeed, the hood is thin stock, maybe 1/16" thick. Let me tell you, not having basically any welding experience to speak of I was quite impressed that I didn't melt through the thin stock. I used 0.035 wire and was on maybe 15% up from minimum on heat. Noticed that when I was at a sharp angle with the sheet it was less likely to penetrate through making a hole. The new helmet with the magnifying glass and the new filter allowed me to see the tip of the wire so clearly that it was quite easy to move it nicely so as to lay a nice bead. Also, longer beads came out nicer, I suppose more of the inner core creates that shielding gas.DavidBarkey wrote: ↑Wed Feb 01, 2023 6:57 am

How about this for many words to say I did weld on both sides.

Re: Case 644 loader repairs
A little wire wheel action and a preliminary coat of paint makes a difference and provides a little protection. Not the right shade of yellow. That's fine.

Re: Case 644 loader repairs
You went from a pile of parts to a working machine pretty quick! The wrong color is better that no paint, can always paint it again!

Re: Case 644 loader repairs
Nice fix Eugen. What was the hole in the hood there for. Do you think.
Or have I asked that question already.

Re: Case 644 loader repairs
Noel, I think they cut the hole in the hood for the exhaust stack of that small diesel engine.
Now I have a 10hp diesel engine that I think would be economical if I could make it work on the 224 only for mowing deck duty. But it doesn't have any easy way to put a front PTO on it, so I'm thinking of selling it.
