Fabcor86r

admin

Question for yall, I have a potential side job coming up. The materials are 3/16 thick mild steel and small “C” channels. My plan of attack so far to weld quickly is .035 solid with 100% CO2, or C25, or 3/32 dia 7014. The welds would need to stay small 3/16 – 1/4 max fillet size and limited heat input so warping is a major issue. Just curious if anyone has used  .035 Hobart’s Fabcor86r with 95/5 (argon/CO2)   or 95/5 (argon/O2)? I have used it with 95/10 C10 gas before and it run beautiful, but was thinking the higher argon % would help me spray at lower heat inputs…. Your thoughts are appreciated.

Reply:Not quite sure what you're trying to do here. FabCor 86 is a metal-core wire and Hobart does not list any sizes smaller than .045. I would stick to .035 solid wire and 75/25 for what you have described.JohnA few weldersA lot of hammersA whole lot of C-clamps
Reply:I though that too. But i looked at their chart and it says .035 in a 33lbs spool. I am just looking for a faster spray weld without the higher heat input of a solid wire. I have sprayed many spools and watched many guys mske nice welds..... Just way too big. Short arc is fine but spray is so much nicer. I know ya can't get something for nothing but thought it would be nice to try first. If it's a pipe dream i will just stick with solid.
Reply:Yes you can get Fabcor86R in 0.035" diameter.  Running it on 95/5 will not get you lower heat input than running it on 90/10.  The puddle will be more fluid with the O2 mix, which is not normally a problem if you're using spray transfer.  If you want to spray with lower heat input, use a pulsed mig power supply, or simply use a higher travel speed.  2 smaller, fast, beads laid down back to back will likely give you lower overall heat input than a single bead the same size.  The only question is can you move fast enough in a straight line to make the difference?Alot depends on the exact welds you need to make.  Are they short beads?  Or long runs?  I don't think you'll get the results you want if your making short fillets.  Long fillets or groove welds would likely work out better.Benson's Mobile Welding - Dayton, OH metro area - AWS Certified Welding Inspector
Reply:Ya i think i can move fast enough. I did alot of .035 solid wire spray with C10 years past. The welds would be done are 11' long total. So i would be back step/skip welding. Was just thinking the metal core with a different gas mix would help making a smaller 3/16" fillet easier. Or had though a higher voltage C10 short arc would work good too. Alot more splatter but nothing a quik sander and brushing can't fix.Last edited by MISSING LINK; 02-27-2014 at 02:01 PM.
Reply:I always thought spray transfer was real hot?Lincoln pro core 125 14''chop saw7 inch grinder,2-4.5 inch grinders,electric die grinder.Half inch drillAnd alot of hand tools
Reply:It is, but the time spent with the heat in one location is typically less. So in most cases if done correctly you can see less heat warpage than with other methods. Not always, but most of the time.
Reply:I recently used some Lincoln 71M in .035" w/C-25 in my Lincoln PowerMIG 200 and was really happy with it.Welded some 1/2" to 5/8" plate, multi-pass. This is a destructive test fixture for a rigging project for So Cal Edison. Worked like a champ.http://all-a-cart.comWelding Cart Kits and accessories
Reply:ZT thats why Lincoln is the best wire and machines ,it is all we use for bridges . Outershield 71 is the best used over 100 tons in the Transportation Hub 7" D1:5  fcm full penitration welds. Real welders DC-600 /LN -9 s

Reply:Thats the go to wire for A-709 50W and 70W for A -588 bridges if they allow FCAW at all.
