The words thrown around that attack the virtues of the E welding rod are words like &#;Sheet metal Rod&#; or &#;Beginner&#;s Rod&#; or &#;Easy Rod&#;. These may be generally true as they are commonly used for these type applications. True it can be used to weld thin material and is a good welding rod to train with that is very forgiving, but what is wrong with that? On the negative side, E does leave a heavy slag formation and is relatively shallow penetrating if not correctly used. But it does yield an extremely high quality weld which, while not as strong as a E, is a strong reason not to discount it. While it won&#;t penetrate as well as an E or even an E, it puts down a large amount of metal relatively quickly without much difficulty. A tight arc and advanced rod angle is needed to help control the slag from rolling in front of the weld on most brands. This rod is good for filling on multi pass welds where layer after layer is going to be needed to make the weld. Though penetration is more shallow, it only needs to bond with the metal laying directly underneath it to provide a quality weld. One of the other things that people in the Western hemisphere may not appreciate about it is that it is the trusted welding rod for root pass welds in Europe and Asia. Yes, that&#;s correct, root pass welds. As far as welds go, every professional knows that a welded joint on a pipe is no better than the root pass. This brings up a very good question: &#;What does Europe and Asia know about the that welders in the West don&#;t?&#; This environment tends to favor a more pragmatic approach to welding as to using &#;what works&#; with the least amount of problems. And seems to be their choice. Having experimented with it myself, it does seem to have some merit as it leaves a smooth inside root and after a little trial and error, is fairly easy to keep it from over reinforcing the root. The easy flowing nature of the would seem to work against it in the root pass, but not so. It simply allows the welder to move a little more quickly. The slag formation on the backside of the weld leaves a cleaner and brighter backside which means less oxidation, an desirable quality in a root pass weld, particularly in pressurized situations. While it may take years or decades for people in the Western hemisphere to rethink the roll in welding, the rest of the world has already seized upon its capability. It&#;s definitely something everyone should be familiar with if they want to be considered a serious or professional level welder.

Well I am a long way from an expert welder, but I will answer your post. is a low penetrator, all position rod, That strikes easy, runs pretty smooth and restrikes easy. The low penetration can be a big advantage when welding thin materials. is a deep penetrator. Yes the for most people runs easier. I only use it for sheet metal. I only use for root passes on thick material. the rod size choice determines the amp ranges you will use. Example on the ranges for 3/32 would be from 40 to 85 amps. obviously use the lower range for thinner material and the higher end of the range for thicker materiel, also each welder machine runs differently. 1/8 inch would be in the range of 75 to 125 amps.I use in the 1/16 size for sheet metal, the listed range is 20 to 45 amps. I use about 28 amps for most of the thin stuff.. much less and striking an arc becomes difficult. As for thickness of metals I use both 3/32 and 1/8 depending on how thick the material is and the heat range I need to use. Again the amp range and the rod are tied together.. Now to my favorite rod, it is . Yes it has some drawbacks, but is sure makes pretty welds. Does not strike the first arc as easy as , and restrike is dowright hard unless you bust the "corn" off of the tip of the rod. use a rough file, (just rub it across the file once) or you can peck it off by striking a brick, or I just "pinch" it off sometimes. Hold a tight arc and dont move too fast, and you will have good results. Others like as a good easy rod to run, you can actually "drag" it on the base metal without sticking after the arc is struck. Restrikes are a little easier than also. I dont think the bead looks as good, but that may just be me. Again take all this with a grain of salt as I would not make a pimple on a good welders..Anyway, there are welding professionals on here, and if nothing else my reply will give your post a bump up and perhaps some of them will see and respond to you. Happy welding.James K0UA
