What's "dig?" And "arc force?"
My Lincoln doesn't have these settings. I know its not a fancy machine, but are the AC/DC 225/125's more suited to a certain rod? It's not often I wander to the stick forum, cause we use mig and tig at work, but now that I'm welding with my machines at home more, its time to head over and do some learnin.

Perfect. Thanks a lot! So, I need to find the sweet spot on my machine, as far as arc length vs amps for a given rod. I like to feel the flux like Jody, but I don't remember sticking the rod. Mine is a standard, low-tech transformer/rectifier machine. No fancy settings on the cracker box.

I start with a 6010 about 60 on the dig and 7018 around 10. Then I adjust from there depending on how much crap I couldn't grind off of the base metal or what I need the weld to look like. If you have never played with your dig setting before run a few beads with whatever rod you have on the low end then crank it up to the max for a few passes so you can feel the difference.
I have more questions than answers

I don't have dig on my cracker box. That's why I was wondering lol. Maybe one day I will have an inverter based machine, but that will be a long time.Poland308 wrote:I start with a 6010 about 60 on the dig and 7018 around 10.

Hey Nathan, I actually used a lincoln 225/125 machine Saturday.
Burned 1/2 of a 1/8" 6010, and 1/2 of a 3/32" 7018. Welded a little part at a friends shop.
Both at 95amps. Dc.
Welded nice as any machine.
Nobody really needs dig, it's just nice to have once in a while.

Just a couple welders and a couple of big hammers and torches.

Awesome! I haven't tried any 6010 yet, just 7018 and 7018AC. The 7018AC, I ran at 135AC, and the 7018H4R was a 3/32" Excalibur that I think I ran at 75 DC+. I originally bought it for my TIG rig, but it ended up paying itself off on that bumper job that you saw on Instagram. I oughtta try 6010 on the next job... I remember liking it in school.AKweldshop wrote:Hey Nathan, I actually used a lincoln 225/125 machine Saturday.

It's too hot for that rod and the motion can entrap slag in the weld that would show up on an X-ray. Until you get some practice after that you might easily run up to 130 amps with a 1/8 in 7018. Depending on position and material thickness.
I have more questions than answers

I agree, do not whip out of the puddle - not designed for that.Jeremy wrote:when learning to weld 7018 1/8" do not exceed 110 amps DCEP do not whip and pause.
But the amps I respectfully disagree - 125 amp minimum for me - personal preference

You can whip 7018 just fine. Many pros do it.
And 110amps is the minimum for 1/8" 7018.
Get your fact straight.

Turned hot enough, any rod in skilled hands will weld without sticking. The most revered stick welder ever, the Lincoln SA series hasn't got it. That said, I tried the Dynasty up with 1/8 7018. It's pretty cool. Neat toy, not worth suicide if you don't have it.
in addition to slag inclusions the whip and pause motion can allow for serious undercut, especially if welding in a groove.nathan wrote:Huh?Jeremy wrote:when learning to weld 7018 1/8" do not exceed 110 amps DCEP do not whip and pause.

I know not to whip, thats not my style. But 110A is really low.Jeremy wrote:in addition to trapping slag (and a lot of it) the whip and pause motion with 7018 cause serious undercut especially if welding in a groove.

Get your fact straight.
the min amps for 7018 is 90 @ 1/8" http://www.lincolnelectric.com/assets/g ... c21010.pdf
i also originally said learning, as skill increases the amps travel speed and specific angles become more of a preference and the material being worked with has some bearing on the amps used.nathan wrote:I know not to whip, thats not my style.

someone using 7018 for the first time doesn't have the same skill to control the same sized puddle as some of the more experienced welders. on some of the projects I've done the amps have been as high as 160 (max Recommended amps for 1/8"), but i don't recommend that for the people learning.
they dont if it goes through ultra sound or xrayJeremy wrote:AKweldshop wrote:Jeremy wrote:when learning to weld 7018 1/8" do not exceed 110 amps DCEP do not whip and pause.

That isnt the problem with 7018.it is not whipped as it will lose gas shielding and result in porosity.sometimes visible to the naked eye,sometimes not.Jeremy wrote:in addition to slag inclusions the whip and pause motion can allow for serious undercut, especially if welding in a groove.nathan wrote:Huh?Jeremy wrote:when learning to weld 7018 1/8" do not exceed 110 amps DCEP do not whip and pause.

Low hydrogen rods are particularly sensitive to arc length because of this.

I strongly agree; other problems like undercut, overlap, slag inclusions, incomplete fusion, and lack of fusion have a higher probability of occurrence using a whip and pause manipulation with a low hydrogen rod.

It is a good practice to start your arc in the weld area just ahead of were you want the puddle and then carry it back to your start spot so that by the time you get a puddle started you will have some gas from the flux to avoid pin holes on your start up on a bead.

What you listed are possible problems encountered with every type of rod,but due to improper technique when whipping.all can be avoided with the right technique.the only thing you cant work around,is the loss of gas shielding.
