The question was of no great importance. I was just curious.
On the Procedures for NR-233, I noticed that the deposition rate and amperage at their lowest suggestion
was LOWER for the 0.72 than for the 1/16 wire.
Why would that be?
http://www.lincolnelectric.com/assets/global/Products/Consumable_Flux-CoredWires-Self-Shielded-Innershield-InnershieldNR-233/c320003.pdfI was looking at different wires to suit my needs, installations of columns and beams in new house construction, mostly.
I have uses NR 211 0.45 and it was OK. I try to pre fab everything in my shop with GMAW. In the field SMAW seems so slow.
I keep hearing about the NR 233 and tried the 0.72. Works pretty good.
But 0.072 seemed a little much ( for my experience level) on the usual 1/4 inch wall tubing.
Any gaps ( my fits don't have gaps, Im talking about fill a connection at the rounded edge of larger tubing, right?) and I start wishing for GMAW and no wind.
I did call and after being handed off a few times talked with someone that pretty much said the 1/16 just ran better at that lowest setting. And the 0.072 ran acceptable at its lowest (recommended) setting.
The Lincoln tech suggested I stick with NR 211 if the seismic qualities are not required. So far we are not prone to earthquakes here in Central Texas.
I have a roll of 0.062 in the suitcase ready for an install later this week.
Oh yea, I wish all those wires came in a 12 lbs rolls. Who wants to lug a suitcase all around with a 25 or 40 lbs roll of wire.
And I would rather put on a fresh roll than have the same 25 lbs roll around for a year or two.
