"THE TORCH"

WAS NICE ENOUGHT TO POST THIS WELDING ROD INFO

The rod (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.

1. Exx1x is for use in all positions
2. Exx2x is for use in flat and horizontal positions
3. 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.

* 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+

So the E6011 has a tensile strength of 60,000psi, can be used in any position and can be used in either AC ot DC- welding. Basically it is a middle of the road welding rod. that can be used by less experienced welders in a variety od situations since it produces a deep penetrating weld and works well on dirty,rusted, or painted metals. A similar rod is the E6010. It produces similar results but can only be used with DC+ or DCRP (DC Reversed Polarity)


Ive been welding for 35 plus years and always asked for and got advice from the local MILLER DEALER,after explaining the welder to be used, the application, etc,then purchased the suggested rods IN BULK packs and never bothered to as what the numbers ment....
never said I was a GREAT weldor, but Ive welded lots of stuff over the years,thats still in use without it breaking,and while its not always the best looking job it STAYS WELDED ...IM working on the LOOKS PART, and the recent MILLER 330 AMP TIG purchase HELPS

Welding Electrodes
1. In most types of arc welding, the welding rod also acts as the electrode to guide the electric arc to the weld location. The American Welding Society (AWS) uses the "E" prefix in welding rod classifications to label welding rods that can be used for arc welding. For arc welding methods that do not use a shielding gas, welding rods with a flux coating are used. The flux vaporizes at the tip of the welding rod, creating a gas that pushes the air away from the weld, resulting in a clean weld.
Steel Welding Rods
2. The most widely welded material is steel, and welding rods are available in many different steel alloys to meet the needs of any particular application. Common types of steel welding rods are mild steel, low alloy steel and stainless steel. Steel welding rods are available with or without flux coatings.
Aluminum Welding Rods
3. Aluminum welding rods are used for welding aluminum parts together, and are particularly suited for welding dissimilar aluminum alloys together. Aluminum welding rods can be used with standard arc welding equipment, metal inert gas (MIG) equipment and tungsten inert gas (TIG) equipment.
Bronze Welding Rods
4. Bronze welding rods are used for brazing applications, joining copper to other metals, and repairing bronze and brass parts. Brazing using bronze welding rods offers increased resistance to salt water corrosion.
Composite Welding Rods
5. Advances in welding technology have led to the creation of composite welding rods. These rods consist of two or more layers of material whose combination results in a stronger, higher quality weld. Flux core welding rods have the flux located in the center of the welding rod. This allows flux materials to be used that may wear off if they were deposited on the outside of the rod. Metal-cored welding rods have a mild-steel outer layer and are filled with a custom mix of metal powders to meet the exact alloy needs for an application.


read the linked info it helps a great deal.

I have a shop back-up welder/genorator thats worked flawlessly for 12 years so far

this is a GREAT EXCUSE, you can use with the wife to justify spending cash on an emergency generator, most wives are not big fans of camping without power for a week, to buy a decent shop welder/generator, the welders can generally be converted to TIG from ARC if you buy a conversion KIT from the manufacturer
k2857-1.jpg

its fully possible to weld aluminum with some of the larger amp rated MIG welders, or convert some arc welders to tig


p20565.jpg

but the cost to modify those existing mig or arc welders with the required accessory kits now exceed the cost of a few of the available new tig welders in some cases.
obviously youll want to compare feature amp ratings and work/time

I bought this miller 252, mig several years ago,
and so far its performed well on everything I've attempted to use it on,
yes I think we all wish quality welders cost less,but you tend to get what you pay for in tool quality.
and it should be obvious that you'll need too read the manual and practice a bit.
before you get good results and loading the mig welder with quality wire
millfeedw.png

and using the correct shield gas is mandatory, and yes there,s adjustments on the welder wire feed and it helps to experiment a bit,
and it should be obvious that the wire must be maintained rust free so spraying it with a bit of wd 40 might be a good idea ,
and certainly covering the welder and keeping it stored in a well ventilated and dry place when not in use is mandatory.

I don,t know anyone whose purchased a better quality lincoln or miller mig welder rated at 200 amps or higher that regrets spending the cash required to do so later on,
but I,ve heard a good many people who bought much less expensive mig welder,
who deeply regret not waiting and spending a bit more on a better welder.
good option if you can afford too do so.

What do those numbers on a welding rod mean?
Posted on February 13, 2008 by admin

Ever wonder what the numbers on a welding electrode mean?
http://garage.grumpysperformance.co...-t-do-stupid-stuff-get-decent-equipment.1669/
All mild steel welding electrodes are designated by a code that’s printed on them. This code takes the form EXXXX, or EXXXXX. So what do they mean?

EXXX, EXXXXX
The letter E designates that is it an electrode

ENNXX, or ENNNXX
The next two numbers (n) represent the tensile strength in 1000′s of psi. For example, an E7018 would have a minimum strength of 70000 psi. There are also high strength steel rods that have five numbers. In this case, the first three numbers represent the strength. An example of this would be 11018. This particular rod would have a minimum weld strength of 110000 psi.

EXXNX, EXXXNX
The next number designates the position that the rod is suitable for use in. It can be either 1,2,or 3
1 means that it’s an all position electrode.
2 means that it’s only for use in horizontal or flat positions
3 means that it’s a flat position only electrode.


EXXXN, EXXXXN
The last number indicates several things such as polarity, type of current, and chemical composition. and is often combined with the third number to designate a special type of electrode.

(1) Cellulose-sodium (EXX10). Electrodes of this type cellulosic material in the form of wood flour or reprocessed low alloy electrodes have up to 30 percent paper. The gas shield contains carbon dioxide and hydrogen, which are reducing agents. These gases tend to produce a digging arc that provides deep penetration. The weld deposit is somewhat rough, and the spatter is at a higher level than other electrodes. It does provide extremely good mechanical properties, particularly after aging. This is one of the earliest types of electrodes developed, and is widely used for cross country pipe lines using the downhill welding technique. It is normally used with direct current with the electrode positive (reverse polarity).

(2) Cellulose-potassium (EXX11). This electrode is very similar to the cellulose-sodium electrode, except more potassium is used than sodium. This provides ionization of the arc and makes the electrode suitable for welding with alternating current. The arc action, the penetration, and the weld results are very similar. In both E6010 and E6011 electrodes, small amounts of iron powder may be added. This assists in arc stabilization and will slightly increase the deposition rate.

(3) Rutile-sodium (EXX12). When rutile or titanium dioxide content is relatively high with respect to the other components, the electrode will be especially appealing to the welder. Electrodes with this coating have a quiet arc, an easily controlled slag, and a low level of spatter. The weld deposit will have a smooth surface and the penetration will be less than with the cellulose electrode. The weld metal properties will be slightly lower than the cellulosic types. This type of electrode provides a fairly high rate of deposition. It has a relatively low arc voltage, and can be used with alternating current or with direct current with electrode negative (straight polarity).

(4) Rutile-potassium (EXX13). This electrode coating is very similar to the rutile-sodium type, except that potassium is used to provide for arc ionization. This makes it more suitable for welding with alternating current. It can also be used with direct current with either polarity. It produces a very quiet, smooth running arc.

(5) Rutile-iron powder (EXXX4). This coating is very similar to the rutile coatings mentioned above, except that iron powder is added. If iron content is 25 to 40 percent, the electrode is EXX14. If iron content is 50 percent or more, the electrode is EXX24. With the lower percentage of iron powder, the electrode can be used in all positions. With the higher percentage of iron powder, it can only be used in the flat position or for making horizontal fillet welds. In both cases, the deposition rate is increased, based on the amount of iron powder in the coating.

(6) Low hydrogen-sodium (EXXX5). Coatings that contain a high proportion of calcium carbonate or calcium fluoride are called low hydrogen, lime ferritic, or basic type electrodes. In this class of coating, cellulose, clays, asbestos, and other minerals that contain combined water are not used. This is to ensure the lowest possible hydrogen content in the arc atmosphere. These electrode coatings are baked at a higher temperature. The low hydrogen electrode family has superior weld metal properties. They provide the highest ductility of any of the deposits. These electrodes have a medium arc with medium or moderate penetration. They have a medium speed of deposition, but require special welding techniques for best results. Low hydrogen electrodes must be stored under controlled conditions. This type is normally used with direct current with electrode positive (reverse polarity).

(7) Low hydrogen-potassium (EXXX6). This type of coating is similar to the low hydrogen-sodium, except for the substitution of potassium for sodium to provide arc ionization. This electrode is used with alternating current and can be used with direct current, electrode positive (reverse polarity). The arc action is smother, but the penetration of the two electrodes is similar.

(8) Low hydrogen-potassium (EXXX6). The coatings in this class of electrodes are similar to the low-hydrogen type mentioned above. However, iron powder is added to the electrode, and if the content is higher than 35 to 40 percent, the electrode is classified as an (EXX18).

(9) Low hydrogen-iron powder (EXX28). This electrode is similar to the (EXX18), but has 50 percent or more iron powder in the coating. It is usable only when welding in the flat position or for making horizontal fillet welds. The deposition rate is higher than (EXX18). Low hydrogen coatings are used for all of the higher-alloy electrodes. By additions of specific metals in the coatings, these electrodes become the alloy types where suffix letters are used to indicate weld metal compositions. Electrodes for welding stainless steel are also the low-hydrogen type.

(10) Iron oxide-sodium (EXX20). Coatings with high iron oxide content produce a weld deposit with a large amount of slag. This can be difficult to control. This coating type produces high-speed deposition, and provides medium penetration with low spatter level. The resulting weld has a very smooth finish. The electrode is usable only with flat position welding and for making horizontal fillet welds. The electrode can be used with alternating current or direct current with either polarity.

(11) Iron-oxide-iron power (EXX27). This type of electrode is very similar to the iron oxide-sodium type, except it contains 50 percent or more iron powder. The increased amount of iron powder greatly increases the deposition rate. It may be used with alternating direct current of either polarity.

Occasionally you’ll see a suffix after the first set, EXXXX-XX These are used to indicate the alloy materials and their proportions. As per the AWS:

-H4, H8, and H16 Indicates the maximum diffusible hydrogen limit measured in millimeters per 100 grams. H4 =4 ml, H8 = 8 ml, H16 = 16 ml

Best information I have found on Different AWS Stick Welding Electrodes today.
Have a project to complete.
Unable to have Eddie Tig Weld it.
His garage is full again yet too many project cars in there no room left.
Going to use my Old Miller Thunderbolt AC Stick Variable Secondary Air Gap Tansformer Welder
Works Very good yet for being made 1972 year.
Run out soon buy 6011 & 7018.
