i weld mild steel 1/8'-1' thick. i use DC+ and E6010 or E7018 most of the time. i've tried welding w/ DC- and these 2 rods, but the arc isn't stable at all and tends to stick a lot when you try to start the arc. i've found that AC makes a 7018 rod stick more than DC+ when you start the arc. but i've usually overcome that drawback by turning the amperage up a little to compensate for the 'colder' arc in AC.
in your case, DC+ would be the best polarity. there are ways of controlling how hot a puddle gets on thin materials so it doesn't burn through, so you shouldn't have to use AC for anything.
magnetic arc blow is when you have electricity flowing in only one direction (DC+ or DC-) and it turns your piece of steel into an electromagnet and it forces your arc to stray toward or away from the puddle, depending on which direction the magnetism is pointed. it can really make you mad if you don't know how to control it before it happens, or while it's happening because it will blow a giant crater in your piece faster than you can fill it. but switching to AC polarity (if you're using a rod capable of AC current) is a cure because then the electricity is switching directions 60 times a second and does not give enough time for a magnetic field to form.

If you’re confused about which MIG welding polarity settings you should be using for flux core wire, and for solid wire…
Since Mac Tool is now a division of the Stanree company, the folks who bring you claw hammers and wood saws, chances they are worth a. as welders are pretty lo. They will be made by the same folks who make cheap crap for places like Harbor Freight. Mac Tools won't be around much longer. This video explains the difference between the different welding polarities that are on welders, and the processes that they are used on. Basically this vide. MIG welding is always going to be positive polarity. Some people confuse MIG with flux core welding. They are not the same, though the equipment used can be nearly the same or identical. Flux core uses a wire that contains a powder flux in the center of the wire. It has its advantages in windy conditions, and offers go anywhere performance.

Here’s why it’s so important to set polarity for mig welding correctly…
If you’re using your MIG welder with flux core wire, and you have it set on the wrong polarity, you’ll quickly notice that your welds will look nasty, like this…

If you want to avoid this headache, then make sure you switch your MIG welding polarity settings any time you change from solid wire to flux core wire.
If you’re not sure what the difference is between using solid MIG welding wire, and gasless (or flux core wire), it’s pretty simple.
We use solid wire when we’re using a shielding gas, and that’s typically C25 gas (25% carbon dioxide and 75% argon) when welding mild steel.
For other processes like aluminum you would use 100% argon shielding gas.
The reason we use gas is because it shields the weld puddle from the contaminents in the atmosphere that can wreak havoc on the weld appearance and strength.
With flux core wire, there’s no need for using a shielding gas because the shielding agent is inside the wire, and when the arc starts it acts as the shielding agent.

Direct Current Electrode Negative
So, for gasless MIG welding polarity (when using flux core wire), your MIG welding polarity settings should be set to direct current electrode negative (or DCEN).
With DCEN, the negative terminal inside your machine is hooked up to your electrode (your MIG gun) while the positive terminal is hooked up to your ground.
Electrons flow from negative to positive, so with DCEN the electrons are traveling from the machine to the MIG gun. They then travel through the workpiece and ground cable, then back to the machine.
It’s opposite for DCEP.
Direct Current Electrode Positive
For DCEP, you now have your positive terminal hooked up to your electrode. The electrons now travel in the reverse direction (from the machine through the ground cable, and back in through the MIG gun.)
I hope this helps you with your MIG welding polarity change.
