I have to weld a manual thumb base plate http://usera.imagecave.com/whitedwar...b/DCP_0001.JPG
Onto my excavator in the area indicated http://usera.imagecave.com/whitedwarf4/Thumb/weld.JPG
The base plate is 1" thick, and I imagine the portion of the excavator boom I'll be welding it onto is at least 1/2" thick.
I have never welded anything this heavy, I'm not a professional welder. Sometimes my welds turn out great. sometimes they don't... This will need to be a very good weld.
The plate was cut off another machine, it had a 1/2" full penetration fillet weld all around the outside of the plate. I'll be looking to do the same.
A few family members have home generators that I can use, but all of them only put out 50A at 220V... My welder can draw 70A at 220V. http://www.millerwelds.com/products/...bolt_xl_ac_dc/
If someone with welding experience could give me some pointers, that would be wonderful. (What type of rod to use, welder settings, etc)
