They stick and won't stay lit, no matter what amps or how close you hold to the work.
They came in a not air tight plastic box with a not airtight shrink wrap around the outside without any dessicant. And it is very humid this time of year, here. I'm guessing they are damp.
I should have paid more attention to the other negative reviews. 7018 electrodes must be dry, and these (the 5 lb package, anyhow) are not adequately packaged.
Edit: I broiled 6 of them in the oven for 45 minutes, and still nada. No arc, at all. My welder works fine with 1/8" 6013 rods.

These rods should get 0 stars. Hard to get started almost impossible to restart. Inconsistent horriable bead. They came damp. It didn't matter what setting the welder was on.

Used a few of these as soon as they came in and they seem to weld great, even in an old 1983 Miller welder. Trying out several differnet brands, so seemed natural to try out Forney also. Will edit later if I decide to go with something different or figure out if one is superior to the other. As for now, these seems to be right up there with the Lincoln Electrics that I normal use and are a little less expensive.

The rods are okay. I've had no trouble welding with them in flat or horizontal positions. For some reason when I try to weld overhead into a 45 degree joint the flux continuously comes off, and I can't get a good weld in. When I used my lincoln excalibur 3/32 7018 I had no problems. I'm still not sure if this is user error as i'm an amateur welder. If you want high quality rods, I would stay away from these.
These rods suck. You get what you pay for. Stick way too much, don’t hold an arc.2017年9月24日 - 已在美国亚马逊上发表
The packaging was good and the rods were dry when they came in. I was able to a get a few clean beads in but I’m wasting more rods than I am burning. I’ve tried turning my machine up and also putting the rods in the oven. I bought a different brand of rods from my local hardware store just to make sure it wasn’t just me or the machine and it turns out those worked a hell of a lot better. So yeah these rods suck. Better of sticking with Hobart or Lincoln rods.
