Im about 9 classes in to my first class, Cutting processes. Never welded or cut before. I just got out of our first Air Carbon Arc class, and it was a nightmare, though thankfully I wasnt the only person messing up. Among other things, we managed to break 6 electrodes. When one of mine broke, it broke more readily than some twigs of the same size would. Obviously she was pretty pissed about all this, so Id really like to avoid this in the future. Is this normal for these electrodes? I tried googling various CAC-A electrodes breaking phrases but didnt find anything, which suggests that it is not.

Reply:It seems strange that they would give you carbon arc cutting before having you weld.
Reply:If you choke up on the rod it will keep the arc hot and there is less chance of snapping the rod. Leave 4-6" sticking out and move the rod back after you gouge until you end up clamped on the non-coated end. You can't lay the stinger down with the rod still clamped. Its a specialty application, best to treat it as such.Lincoln 275 SquarewaveLincoln SP 250

Reply:Choke up for sure, they run best at about 6" sticking out from the holder, Those 1/4" rods are so fragile, I prefer 3/8" rods they break less but you need at least a 400 amp machine.We've done so much, for so long, with so little. Were now qualified to do anything with nothing !

I would like to run 1/4" carbons at roughly 300-400 amps.So, example: I have a spare Thermal Arc 250TE TIG inverter which is worthless (HF/gas start is broken, but works fine in MMA mode). This is rated at 210amp at 100% DC.If I found another 250 amp inverter... any inverter... would they have to be matched machines? Would it have to be another TA 250TE, to ensure the load is balanced? Or could I get away with pairing with, say, an XMT 300, which is a totally different machine?And then it's just a case of joining cables together, running off our massive 3phase supply, setting each machine to 200 amps to give 400 amps total, and off we go? Have I got that right, or wrong?

Reply:If your rods are breaking you must be hitting them on something, if your rods are breaking from just having to carry and bring to class ,the easiest way to keep them from breaking is, ask your teacher for the box the rods come in. you must be using or learning with very very small maybe pencil size or smaller rods. everybody at some point breaks rods, I really dont have that problem. I am using 1" rods with a 1500 amp power supply!
Reply:Don't take this the wrong way, but we all would like to see pics or video of your 1" rod in action.

Reply:You guys are funny so funny you'all much really lack in the experience of carbon air arcing. Its one of the things i specialize in. If your lacking in air arc experience most likely your also lacking in open root welding using copper backing, thats something else i specialize in with stainless, nickel, mild steel, low alloy with over 100 metal alloys. You guys are so funny you probably think im making it up that i have 2 navsea 250-1500 certifications 2 inconel 112t certifications,2 inconel 182 1 of which is navsea and the other being dissimilar metals fabrication a 309 dissimilar metal fabrications certification 12018m hy100 certification, ferralium 255 certification, harris 630 for the ge lm2500 front frame casting of which i've done 2 production runs 100 each. Still laughing boys ge/ruston lm5000 ge lm6000, 7018, 308 navsea, 316lt-3, 320lr, 410nimo, ok68.55, 958ht-0, you ever thinks thing are so funny, in order to do my job i had 7 different sizes and shapes of copper because of that 1" carbon rod working on or out of a 600 degree preheat oven. You want a really good laugh, because im laughing now, repaired and fabricated 6 full ge ship set of trident and ssn 904 propulision systems, sstg-2, cvnx, westinghouse sunny vale,westinghouse cvn, the west 1 production model, i bet you neverheard of a project call ge ipmp2-improved performance machinery phrase 2, i fabricated the ge thin wall prototype for ssn seawolf 21. You guys are probably the type of welders that have or had 1 weld booth worked in 5 a week on days or swing, in order for me to get where i was and specialize in it i had to work in 4-5 different weld booths a night, 20-25 a week. That open root specialized skill of mine is with 5/32 rod or 1/16 dualshield wire, so you might think that 1" carbon rod really is no joke or laughing matter. Heres something that you might find funny or want to really laugh about, i was the only welder without a hy80 certification, because i didnt have the time? At one point in time i was coming in contact with over 80% of the work cycling thru the re and ue depts either welding or defect cavity arching
Reply:Hey i got a couple question up on weld messages talk board on another site see if you can answer the mismachined post or the mild steel post, the response side stepped the answer most likely because the admin couldnt answer it how many different ways can you fill that mild steel defect cavity , i can do it 6 differen ways with no problem passing rt inspection
Reply:Well we'll aren't we special.
Reply:Yes i am there was no other and i havent work in a foundry in 20 years, your a good indication with that way of responding just another fourm with people that have welding experience but couldnt pass the 7018 and 316 vertical up on a double vjoint groove because you lack air arc experience and couldnt arc out the groove the right way. On a 1 1/2 thick test plate, its not really being special its called custom engineered products
