That depends on the diameter of the rod if it is 1/8" set your amperage between 125 and 140.

7018 electrodes should be used with DC positive polarity. This means the electrode holder is connected to the positive terminal of the welding machine, resulting in better arc stability and smoother weld deposits.
its 7018 grade rod can use
depends but i would use a 3-32 rod preferably a 7018 hope that helps
3/32 85-100 1/8 110-160 is what I run
Yes, the electrode holder (stinger) is positive and the ground is negative which means you would be welding DC positive.
That depends on the diameter of your rod which depends on the thickness of the material you are welding. An e-7018 1/16" rod start at about 70 amps. A 3/32 rod start about 90 amps. A 1/8 rod start at about 110 amps. These are ball park ranges and you will need to adjust to suit. When the scale from your test beads chips off easily you are exactly where you need to be with the heat.
no 7018 is for carbon steel 9018 for chrome 308 is for stainless
1040.
The E 7018 welding rod is typically recommended to be used with direct current (DC) and reverse polarity (DCEP), where the electrode is connected to the positive terminal. This polarity helps achieve better arc stability, penetration, and overall weld quality. However, it can also be used with alternating current (AC) in some situations, though DC is generally preferred for optimal results.
