What should the welding machine be set at for a 7018 welding rod in 3G?

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


What is the difference between 7018 and 6010 electrodes?

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.


What temperature should you put a 185 miller welder to weld a 7018 rod?

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.

What are the two polarities used with direct current welding?

reverse polarity and straight polarity The answer is right but a bit of furthur explanation is required. Polarity can be changed in DC output welding sets. The heat of the welding arc is concentrated on the positive terminal. So when thick plates are welded as more concentration of heat is required on the job the job is kept +ve ie. straight polarity is used. For thin plates concentration of heat is on the filler rod ,so reverse polarity is used.
