There is not two separate strengths like bifocals. I have just worn
bifocals for so long that I habitually tilt my head back, although there is
not a separate part of the lens to look through. No split like bifocals. I
always used the no lines.

If they're anything like Toric lenses for astigmatism, then they're
weighted(ever so slightly) at the bottom and they stay more or less in
place so long as your eyes don't dry out. They depend on being able
to "float" on a film of moisture, otherwise they stick and can rotate.
Funny story: Ever try MIG welding on the underbody of a car while

You just slap the side of your head really hard when they rotate .........
They work something like this: I can see great from 6" in front of my face
to about 12 feet, where it is slightly fuzzy. After that, it gets more
fuzzy, but not to the point that I can't drive. Drove 360 miles today. So,

Thanks Bruce. Im still looking in OC. The Hobart is up north at my
homestead...along with me. I got home about an hour or so ago at 2am.
The van is now parked in a buddies yard behind his big machine shop, at
least for a month or so. Tags expired while I was in the hospital a year

It's tricky, fun, and doable. Get your amperage so it just burns, and whip
in and out of the puddle. Staying still will just get you a hole. Keep a
short arc to place the next puddle, but you can lengthen it a little to whip
out and in just as soon as you get a puddle, whip out, let it cool for a

Thanks Steve - heard of this - 6011 DCEN on thin metal. Have a few
6011's - must try it some time. "Stack of dimes" - will see if can
get that. -- Rich Smith

Remember that some rods can have special and functional uses when used at
non mfr. settings. The one that I have used a lot is 3/32" 6011 with
stinger negative to field weld .065" tube. A case where you just want to
put a "stack of dimes" on there to hold it together for a long time. Quite

Hi all posters on this thread
For what it's worth - generator DC welding machine at work - tried
running our 6013's on the Negative pole (DCEN) and observed that
visibly they do run better that way.
Follows what the manufacturer says on the packet - AC or DCEN.
Reckon DCEP for Basic (7016 and 7018) and Cellulosic (6010) always

Not really- Start stacking thin plates one on top of the other. Strike
an ark with DCEP stick, and see how many plates you can get to melt
together as you run a bead.
Then do the same with a TIG torch, set up for DCEN at the SAME AMPERAGE
as the stick was, and again run a decent bead. I'll bet you that more
