Hi...
I finally started on my first welding project; a welding table. (I said first, not most original. ) I'm using primarily 1/8 inch (3.18 mm) 1 1/2" angle iron because I got five 7 foot sections for free from my cousin, along with two 1/4" (6.35 mm) 12" x 33" plates for the top that I found on Craig's List. Unfortunately, the angle's painted, and it's taken me more time to grind off the paint from three of the 15 angle pieces than it has to cut all 15 pcs. and set up and weld one corner.
Anyway, I finally set up the welder for the material I'm using by welding scraps from the cutting process. Then I set up to weld the first corner of one of the two rectangular frames. I mitered the corners during cutting, so I got everything square, clamped, and welded the flat portion (the portion where the weld is parallel to the ground. This welded normally with a little weaving and actually came out quite nice.
To the strange part... Then I went to weld the vertical, inside joint of the miter, starting at the bottom and working upward. Everyone talks about the frying or buzzing sound that indicates everything is set up correct. This was certainly present on the weld parallel to the ground. But on this vertical weld, I got one frying pan sound, and then the arc became almost silent, like the whooshing of air. But it was still a good arc, so I proceeded to make the vertical weld, all the time wondering if I was in the Twilight Zone. This weld also turned out good.
So where the heck is my frying sound??? What could have caused this? What normally causes the frying sound, anyway?
I'm using a Dayton 85 amp hobby-type welder set on the highest heat setting, and 0.8 mm L-56 wire with 75%/25% Argon/CO2 mixture at 20 cfh. There was no appreciable splatter on either weld, but there was a brown powder that brushed right off, which I understand is normal. (But didn't occur until I changed the polarity to the correct polarity for welding with gas.)
Can anyone provide some input as to what happened? I'm really confused...
