I bought a box of Blueshield 7018 rods (Air Liquide house brand). Not much info on packaging. I tried to run the rod, and boy, it was as if my welding table was a big magnet: the puddle was travelling front and back and side to side... never seen anything like it! I checked on the rod and it is labelled «AC». I ran many brands of 7018 and they were all pretty good (even some Hobart 7018 AC without any problem). I went back to other rods and they were fine... I wonder why it behaved this way; any cue? It is as if they were magnetized... (?).
Yes I do... Jasic Razorweld Razorarc 200 di.
It looks like an intense arc blow going on and on... I changed position and even pieces to weld; still behaving erratically...
AC rods should run ok on DC inverter; or maybe not always...
Yes, great suggestion; but what puzzles me the most is that it's an ongoing arc blow... usually, you start your weld and at some point you start to get arc blow. In this case, the arc blow begins as soon as you light the rod... I'll need to do more tries. But I want to get it out of the way; is it possible that some AC rods could behave like that on a DC inverter?
i would start by turning down the arc force.
AC rods will have a lower voltage requirement so you may need to set up the welder a bit different and also change your arc length a bit.

tweak it until it breaks
I almost always run my 7018 at «0» arc force... I like the buttery smooth feel. So, in this case, that's not the cause... I am talking of an extreme reaction... for exemple, even with a pronounced drag angle, the puddle rushes in front of the rod! Never seen anything like it.

and what size rod?

3/32... running many amperage settings, from 70 to 85, depending of position...tweake wrote: ↑Fri Aug 16, 2024 5:45 pmwhat amps are you running?Rodbelan wrote: ↑Fri Aug 16, 2024 8:57 am I almost always run my 7018 at «0» arc force...
