Can a e6013 welding rod be used on a 110 volt arc welder?
Just got one and been using the 1/16" rods and they are not working for me. Burn too quick and become glowing, red hot when used. Have used e6011, e6013, and e7018 but on a 230 volt. Not worried about ruining metal but will it ruin arc welder?
kinda hard to say. you didnt state what you thickness you are welding and at what amperage. it would also help to know what type of machine you have and what the duty cycle is.
you either need to turn down the amps or switch to a thicker rod. it shouldnt hurt the welder just dont exced the duty cycle. step up to a 3/32 rod wich can weld up to a 1/4 inch plate between 40-125 amps. below is how to decode the numbers on the rod.
Arc welding electrodes are identified using the A.W.S, (American Welding Society) numbering system and are made in sizes from 1/16 to 5/16 . An example would be a welding rod identified as an 1/8" E6011 electrode.
The electrode is 1/8" in diameter
The "E" stands for arc welding electrode.
Next will be either a 4 or 5 digit number stamped on the electrode. The first two numbers of a 4 digit number and the first 3 digits of a 5 digit number indicate the minimum tensile strength (in thousands of pounds per square inch) of the weld that the rod will produce, stress relieved. Examples would be as follows:
E60xx would have a tensile strength of 60,000 psi E110XX would be 110,000 psi
The next to last digit indicates the position the electrode can be used in.
EXX1X is for use in all positions
EXX2X is for use in flat and horizontal positions
EXX3X is for flat welding
The last two digits together, indicate the type of coating on the electrode and the welding current the electrode can be used with. Such as DC straight, (DC -) DC reverse (DC+) or A.C.
I won't describe the type of coatings of the various electrodes, but will give examples of the type current each will work with.
ELECTRODES AND CURRENTS USED
EXX10 DC+ (DC reverse or DCRP) electrode positive.
EXX11 AC or DC- (DC straight or DCSP) electrode negative.
EXX12 AC or DC-
EXX13 AC, DC- or DC+
EXX14 AC, DC- or DC+
EXX15 DC+
EXX16 AC or DC+
EXX18 AC, DC- or DC+
EXX20 AC ,DC- or DC+
EXX24 AC, DC- or DC+
EXX27 AC, DC- or DC+
EXX28 AC or DC+
CURRENT TYPES
SMAW is performed using either AC or DCcurrent. Since DC current flows in one direction, DC current can be DC straight, (electrode negative) or DC reversed (electrode positive). With DC reversed,(DC+ OR DCRP) the weld penetration will be deep. DC straight (DC- OR DCSP) the weld will have a faster melt off and deposit rate. The weld will have medium penetration.
Ac current changes it's polarity 120 times a second by it's self and can not be changed as can DC current.
ELECTRODE SIZE AND AMPS USED
The following will serve as a basic guide of the amp range that can be used for different size electrodes. Note that these ratings can be different between various electrode manufactures for the same size rod. Also the type coating on the electrode could effect the amperage range. When possible, check the manufactures info of the electrode you will be using for their recommended amperage settings.

Note! The thicker the material to be welded, the higher the current needed and the larger the electrode needed.
SOME ELECTRODE TYPES
This section will briefly describe four electrodes that are commonly used for maintenance and repair welding of mild steel. There are many other electrodes available for the welding of other kinds of metals. Check with your local welding supply dealer for the electrode that should be used for the metal you want to weld.
E6010 This electrode is used for all position welding using DCRP. It produces a deep penetrating weld and works well on dirty,rusted, or painted metals
E6011 This electrode has the same characteristics of the E6010, but can be used with AC and DC currents.
E6013 This electrode can be used with AC and DC currents. It produces a medium penetrating weld with a superior weld bead appearance.
E7018 This electrode is known as a low hydrogen electrode and can be used with AC or DC. The coating on the electrode has a low moisture content that reduces the introduction of hydrogen into the weld. The electrode can produce welds of x-ray quality with medium penetration. (Note, this electrode must be kept dry. If it gets wet, it must be dried in a rod oven before use.)
check your owners manual for you machines duty cycle
Duty cycle is a welding equipment specification which defines the number of minutes, within a 10 minute period, during which a given welder can safely produce a particular welding current.
For example, a 150 amp. welder with a 30% duty cycle must be "rested" for at least 7 minutes after 3 minutes of continuous welding.
