INvertec 275-s Understanding

admin

Hello everyone I am relatively new to welding and I am having some issues and I believe my understanding of the machine is the problem. I was trying to do an open root in horizontal weld and I kept having serious issues.Machine was set on 200 Amps with a +2 Arc Force.Remote was set on 6-6 1/4 I was using 6010 rod I tried to gap it 1/8 and My bevel was 30 degrees. When I would turn the remote amps past 5 I would start burning right through and the keyhole would not close. I was welding half inch steel. If turned the amps below 5 I couldn't keep an arc and the electrode would stick. It was a very frustrating four hours.
Reply:I run 1/8 6010 at around 85-90 amp. Open root joint on a pipe weld I'll use a strong 1/8" gap and a 1/8" land. Watch the key hole and whip the rod in and out accordingly. When using 6010 rod you should have your machine set for a "stiff" or "strong" arc.
Reply:So I picture you're in a booth with a remote hanging beside you.  With Miller inverters, when you set the machine at say 200 amps, the remote will decide a percentage of that 200....5 on the remote equals approx. 100 amps.  I believe that on your Lincoln, it doesn't matter what the machine is set at.....5 on the remote gives 50% of total machine output which could equal approx. 140 amps.  I'm guessing, if there are no problems with the remote, you should be putting the root in at about 3 on the remote.  Quick check of your remote....what happens if you run a pass on the flat with a 3/32" 7018 on your 1/2" plate?  5 on the dial should be way too hot, lots of buckshot, rod turns red pretty quick.  3 on the dial should be slightly cold for the 3/32" 7018 but a good starting point 1/8" 6010 open root.Last edited by OldSparks; 10-13-2013 at 10:27 AM.

Reply:I have a 250s. I think its almost the same. You have to select SMAW CRISP for arc force. The nominal setting for exx10-14 is 6. SMAW SOFT is for Hot Start. SOFT is recomended for hard restarting 7018 but I only use CRISP unless Im using GTAW.  Ive never tried the remote for SMAW. I thought the remote was only for GTAW.   I think SMAW SOFT would help for scratch start TIG when you dont have a remote.  Are you in SMAW CRISP?
Reply:Ditch the remote. Run it at 85. Problem solved.
Reply:Thank you for all the replies guys, that makes some sense. Turn up arc force while setting remote at 5 that should give me what I need. Not sure what the crisp is I will take a better look at the machine tomorrow at school and get back to you. + the welding genius will be there and likely be able to fix my issues. My teacher on Saturday would rather not be there I suspect.... -____- Which doesn't add any value to the education. Thanks again everyone.
