a welding rod
7018 structural 6010 root, 7018 cover for pipe
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
That depends on the diameter of the rod if it is 1/8" set your amperage between 125 and 140.
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.
no 7018 is for carbon steel 9018 for chrome 308 is for stainless
6010 penetrates deeper than 7018 does. It is a "fast freeze" rod - the puddle solidifies quickly. There's not much slag and it chips off easily. It also requires DC electrode-positive polarity. If you have an AC-only welder like a Lincoln AC-225, get 6011 which is almost the same rod but it will run on either AC or DC. Most guys who use 6010-series rods are welding pipe. Guys who weld bridge decking grab this rod first because of its penetration. 7018 is a rod with low-hydrogen flux. It produces a LOT prettier weld than the 6000-series rods do, but it's got to be stored in a rod oven because moisture in the air changes the way it welds. These are generally used for structural welding. These are two of the most general-purpose rods out there.
