needing advice on a good flux core wire

admin

I got an Ln 25 that Im using to weld equipment on the job site but Im having problems with the flux core wire Im using if I weld any position other than flat it runs and spits off. Im using fabsheild 21B I do a lot of vertical welds so I need a fast freezing wire. I have gone to my local welding supply shop but they dont know much more than I do I would appreciate any advice thanks
Reply:Lincoln NR 211 for under 3/4" Nr 212 for over 3/4" or NR 232-233 if you would like something with better charrpy impact numbers.ESAB Coreshield 8 is my favorite FCAW 7018 substitute. THe NR 211-212 are the easiest to run but are prone to cracking  at lower temperatures or in hight impact cyclic fatigue structures. If you are welding on something dynamically  loaded I would go with the Coreshield 8Good Luck
Reply:21B is a good all position wire. It can handle verts and overhead all day long with no problems. Look someplace else for the answers. What machine and settings are you using? Is your polarity correct for that wire?....What are you welding on? Is it in a magnetic field or magnetized in some way? Dont be too quick to blame the wire.....
Reply:ok  have been running beads trying to get my settings right Im running 26 volts 170 in of wire, reverse polarity welding on mild steel 3/8 plate mainly new metal the problem Im seeing is no slag on the top of the bead I have tried voltages between 18 and 32 and wire speeds between 140 and 220 it all does the same type of bead. the power source is a trailblazer 302 that I got 6 months ago before that I had a bobcat 225 that ran it with no problems. Should I have slag covering the whole bead? if I run any higher wire speed it starts hitting the bottom of the puddle. The wire is 1/16. I was running .045 wire doing the same crappy beads. my stick out is about 1 inch  any advice would be appreciatedLast edited by idacal; 06-14-2008 at 01:15 PM.
Reply:What brand and # wire are you using.  You said reverse polarity.  Electrode - or +?If you know the brand and # wire, you can go to the website of the producer and find a spec sheet for that specific wire.Those #s sound a little high for 1/16 wire.  .068 NR211 MP runs at 130 ipm 20 volts.Where is weldrwmn?Here is a welding guidehttp://content.lincolnelectric.com/p...ure/c32400.pdfand a lincoln spec sheethttp://content.lincolnelectric.com/p...ure/c32000.pdfDavidLast edited by David R; 06-14-2008 at 04:18 PM.Real world weldin.  When I grow up I want to be a tig weldor.

Reply:I just made a post about this in another forum. In short NR-232 is an awesome wire. NR-203 is also not bad either.http://weldingweb.com/vbb/showthread.php?t=22086
Reply:for that particular wire, you will want to run the following settings (keep in mind that they are only a starting point and you should fine-tune according to your particular tastes)1/16 flat/horiz: 19volts, 100ipm       vert/up:  16 or 17volts, 60-70ipm.045 flat/horiz:  18volts, 175ipm       vert/up:   16volts, 125ipmyou should have slag covering most/all of the bead.

Reply:Thanks guys for all the advice. I was welding to hot and overrunning the wire I went and bought some coresheild 8 that stuff is great and makes a nice smooth weld thanks again for all the advice
