E7018 is a shielded metal arc welding (SMAW) electrode. 'E' stands for electrode. '70' stands for 70000 psi minimum as welded tensile strength. '1' designates the position the electrode can be welded in, in this case all positions. '8' classifies that the electrode is a low hydrogen electrode and contains a higher amount of iron powder.
Welding rods are manufactured by a number of companies , but are sold by retailers that deal with these supplies.
They are mild and low alloy metals . the rods are iron coated for a better distribution of the flux metal. They are normally used for general fabrication, heavy sheet metal work and shelving.
About $90 for a 50lb canister

a welding rod
7018 structural 6010 root, 7018 cover for pipe
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.
what is the difference between 7018 and 7018-1
no 7018 is for carbon steel 9018 for chrome 308 is for stainless
1040.
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.
