September 6, 200817 yr Hi The only experience in welding i have so far is mig welding. I recently bought a new Tig Ac/DC welder. Which can also do stick welding. And I found en bunch of different electrodes but don
September 6, 200817 yr All the electrodes you have are designed for mild steel, and are covered under the AWS (American Welding Society) Classification A5.1. The first 2 digits indicate the tensile strength of the filler metal in thousands of PSI. So for example 6013 has a strength of 60,000 PSI. The 3rd digit indicates the position the electrode can be used. "1" can be used in all positions. "2" can only be used in the flat and horizontal positions. "4" is used for the DOWNHILL vertical position. So in the 6013 example the 1 indicates you can use that rod to weld any position. The last digit indicates the type of flux coating. This changes the properties of how the electrode preforms, and also whether it used with AC, DCEP, or DCEN. In the 6013 example the 3 indicates the flux coating is made of Titania potassium and can be used with all 3 current types. It provides shallow penetration, and is good for thin metals or making a pretty cap on a multiple pass weld.

Even professional weldors have mixed results with it. All I can tell you is that AWS classification A5.15 has the specs for cast iron electrodes. If you want to repair something, I suggest practicing on some scrap pieces first, and doing a good amount of research as well. Edited September 6, 200817 yr by moya034

September 7, 200817 yr By the way you may not want to try welding that firepot..most do not come out well and crack away from the weld.I know there are folks that do that well and make them last forever. If it was mine i would put a plate across the crack and another underneath and bolt through all three pieces. Lots of forges have been repaired this way.
September 8, 200817 yr If u do weld the firepot, pre heat the firepot and the rods and grind the crack before welding it, and peen the weld after you weld it
September 8, 200817 yr Author If there is such chance it can go wrong i ‘m not going to weld the firepot. The forge works very well with the cracks so i’m going to leave them in. I have the forge for 3 years now and the cracks haven’t grown. Sometimes clinker sticks to the cracks but that’s not a big problem. I tired to attach some pics i hope u can see them. Thanks a lot for all the advice. Edited September 8, 200817 yr by FTK
September 12, 200817 yr I have pretty much all of the info that you will need right here:http://www.iforgeiron.com/forum/f56/craftmans-sears-stick-welder-6581/ Hope this helps. Good luck!!
