My Thunderbolt 225/150 AC/DC isn't working right in AC. I have gone as high as 170 amps with a 7018 1/8" rod but it still doesn't maintain an arc. Same rod on same machine works fine in DCEP at 100 amps.What should I look for when I open it up to look for issues?Thanks!GravelThe difference between theory and practice is that in theory there is no difference.
Reply:Is your rod 7018 or 7018AC?
Reply:If your Thunderbolt has a low and high range tap, use the low range tap. On the low range tap, the OCV is higher and gives you a better chance at running a 7018 on AC.If it's not a 7018AC version rod, they tend to run badly on AC. When not marked, it is a DC+ preferred rod.Dave J.Dave J.Beware of false knowledge; it is more dangerous than ignorance. ~George Bernard Shaw~ Syncro 350Invertec v250-sThermal Arc 161 and 300MM210DialarcTried being normal once, didn't take....I think it was a Tuesday.
Reply:pin2hot,Rods are 7018H4R.Dave,I think I tried both high and low range but I'll have to try low just to be sure. I'll get some 7018AC just to make sure that my machine is working right. I'll run my current rods DCEP.Thanks!GravelThe difference between theory and practice is that in theory there is no difference.
Reply:If you like running AC, 7014 rods run nice that way - one of my favorites So do 6013, but don't tell anyone you use them - 7018 purists my shoot at you LOL (kidding guys )For the record, for overall weld quality it would go 6013, 7014, then 7018 at the top.Dave J.Dave J.Beware of false knowledge; it is more dangerous than ignorance. ~George Bernard Shaw~ Syncro 350Invertec v250-sThermal Arc 161 and 300MM210DialarcTried being normal once, didn't take....I think it was a Tuesday.
