Re: tack weld SMAW 6010 cellulosics - yes!

Hello everyone
Decades after first mention of tack welding with SMAW 6010's, on then
welding newsgroup and on r.c.m., I tried - and am bowled-over!
In Britain almost no use of 6010's and 6011's.

I think that is in part because 6010 doesn't run on all the machines that could fly through 6013 and 7018.  Only in recent years have I see mif price import machines able to run 60610 reliably, and some of them have shown mixed results from one machine to the next of the same model.   I can't speak to older transformer machines.  My Lincoln cracker box barely ran 7018 well.  My only other transformer machine is the Miller MIG box.  WEll I do have an ancient Hobart (Real Hobart, not Miller Hobart) generator welder, but my dad parked it decades ago when it melted its starting battery.  I haven't got around to trouble shooting it.

I've used for a couple of decades of root-running.
"In background" a bit because my Miller Dynasty 200DX welding machine
won't "keyhole" with 6010.  Which was my first application of
cellulosic 6010's and 6011's - "keyhole" the root of a V-butt weld.
Well, trying to weld 10mm A/F 6mm nuts to the periphery of a 10mm
wall thickness tube forming the shell of my rod-mill, suddenly
recalled 6010's used for tacking in North America.
So that's "open arc" - use like a 6013 (7018 is "open arc" but very
close-up due to cup formation at end of rod - so not that similar)
Wow!
That was a trick I missed!
* instant arc-up and pool formation
* fluidity
* very "clean"
* fast freeze
* directional directable arc
* smooth and pleasant to use
 

Thanks for the info.  While the odds are never zero I am unlikely to run 6010 any time soon.  There is always that chance.  I will have some questions about mid thickness overhead welding soon.

Well everyone - best wishes and thanks for all the help along the way,
Rich S

Same to you.
