DC help

[Shield Arc]

P.S. How is the polarity supposed to be for flux core?

You really need to look at the manufacturer's recommendations. Majority of flux core self shielded wires are DCEN, but just to name a couple NR-305, NS-3M are DCEP.

Would it say on the spool of wire, then?

Sometimes, sometimes it's in the literature in the bottom of the box. Or you may have to go to the manufacturer's website.

For self shielded flux core, it should be dcen (mig gun negitive) I think some dual shield flux core need dcep.

In case you are interested, You should be able to run a Voltage Sensing feeder off of that new stick welder if you ever want to put down some wire. I am unsure about that brand but most will do it.

Here's some Mig welds I just did with a 46 year old SA-200, (no CV box) LN-25, and C25.

Those are nice welds. If I could find a used VS feeder CHEAP ($100 or less) I would probably pick it up. I dont really feel the need for a mig right now. I would rather have a tig rig for it. But if I found a deal that good I couldnt help buying it.

You get good with SMAW, and scratch start Tig welding first, then go to Mig, you'll pick it up in a heart beat!

Did you ever run a mig? Those things will ruin you, way too easy..:laughing:

Nope. Holding the gun of a princess auto 90 amp flux wire welder is the closest I have ever came to using one. I am still trying to learn stick. I have gotten to the point where I can make nice looking beads on a piece of plate, now I just need to get good at joints. 7018 is a piece of cake to make a nice looking bead on a piece of plate. One I can get the stack of dimes with 6011, I will move on to fillet welds.

Remember a lot of that comes from the correct arc length. Once you find the correct arc length, and heat settings getting the stack of dimes will be easy.
