What polarity do you run with E6010?
Cutting with these electrodes produces big-time sparks and large globs of molten metal. 6011 runs on AC and direct current electrode positive (DCEP), while 6010 runs only on DCEP. This gives 6011 an advantage if you have an AC-only machine. I have found, and think most welders will agree, that 6010 runs more smoothly.
Why is reverse polarity preferred for magnesium welding?
DC reverse polarity provides better cleaning action of the metal and is preferred for manual welding operations. The welding technique for magnesium is similar to that used for other non-ferrous metals. The arc should be maintained at about 5⁄16-inch. Tack welds should be used to maintain fit and prevent distortion.
What are the advantages of reverse polarity?
“Straight” and “reverse” polarity are common terms for “electrode-negative” and “electrode-positive” polarity. Welding currents with electrode-positive (reverse) polarity result in deeper penetration, while electrode-negative (straight) polarity has the benefit of faster melt-off and faster deposition rate.
What is E6010 welding rod used for?
Pinnacle Alloys E6010 is an excellent choice for construction, shipbuilding, general purpose fabrication, maintenance welding, out-of- position X-ray welds, pipe welding, and vertical or overhead plate welding.
What polarity is used for 7018?

Is 6010 a filler rod?
This makes it ideal for welding at a stiffening angle or downhill passes. The 6010 electrode has ample strength to do the job and is faster than other electrodes in its category….Overview of 6010 welding rods.
Is DCEP reverse polarity?
DCEP was also historically known as Direct Current Reverse Polarity (DCRP) or simply “Reverse”, whereas DCEN was also known as Direct Current Straight Polarity (DCSP) or simply “Straight”. In TIG welding, the split of heat between the anode and cathode is significant.
Do you reverse polarity when welding aluminum?
More often with GTAW, aluminum is welded using alternating current (AC). In AC welding, the arc’s action when the electrode is positive and the workpiece is negative, called reverse polarity, breaks up the oxide on the surface of the aluminum, making welding much easier.
What are the benefits of using AC polarity?
The alternating current between positive polarity and negative polarity allows for a steadier arc for welding magnetic parts. Fixes problems with arc blow. Enables effective aluminium welding. AC welding machines are cheaper than DC equipment.
What is the easiest welding rod to use?
The easiest welding rod to use is a 1/8″ (3.2mm) E6013 rod. The fact that most welding schools start teaching with E6013 is proof enough. It has an easy arc strike and is the most forgiving to manipulation errors during welding.
What does the 60 stand for in E6010?
The “E” indicates an arc welding electrode. The first two digits of a 4-digit number and the first three digits of a 5-digit number stand for tensile strength. For example, E6010 means 60,000 pounds per square inch (PSI) tensile strength and E10018 means 100,000 psi tensile strength.
What does the 1 in E7018 stand for?
The “E” in E7018 electrode indicates a tool used for an arc-welding process. The 70 means it makes welds that are very strong (70,000 psi). The 18 means two things: The “1” means the electrode can be used in any position, and the “18” means low hydrogen and usually DC current.
