  • Arc Welding Info

    ill get down to the point.... im not that good in intros



    Good welding




    Ampere too high




    Ampere too low

      Stick Electrodes

      ex.
      E6013

      E = stick electrode
      60 = tensile strength
      1 = position
      3 = type of material


      Ampere rating for electrodes

      size of electrode x 1000 with 10% approximation

      ex.
      1/8 * 1000 = 112.5A ~ 137.5A


      Essentials in Welding (things to consider)
      Material
      Area
      Electrode Size
      Arc length
      Travel speed
      Welding Angle


      Note
      Welding is a big approximation. Be careful not to overload your machine


      Tips
      It is better to increase cord length (to outlet or breaker) than to increase the length of the welding cable (to electrode holder and or ground clamp)

      For portable welding machines, remember to let the unit rest. Using it for a long time (and jobs whose cross sectional area is large and or cutting) to prolong lifespan, the machines like us humans also needs to rest.


      Hope this helps maybe. Got this info through experience and of course READING.

          nice SMAW, this is a big unit though

          Ill try to put some info on TIG later if I still have the energy left.

          and miller btw is one of the best if not the best welding machine

            Nice to know how to read the E6013.

            Thanks Silhouette..

            Will try to approximate the approximates,.,hehehe.

                TIG Welding

                -can be used in most kinds of metals
                *MS, BI, GI, stainless steel, aluminum, nickel alloy, magnesium, copper, brass, etc. etc. etc.
                -high quality and clean weld
                -less to no sparks
                -no slag residue
                -used best in thin metals


                Kinds of tungsten rods



                Shielding Gas
                -shielding gas is used instead of slag in stick welding
                -protects weld area from atmospheric disturbance
                *prevents contaminated areas or blow holes

                Commonly used shielding gas
                1) Argon
                2) CO2
                3) Helium

                never use gas that supports combustion like oxygen as shielding gas

                  Re: Arc Welding Info

                  nice tips.. TIG are very versatile and strong mostly used in welding thinner metal tubes like reynolds, 5130 cromo and 7071 like my bike
                  just do it work it make it!:gun:

                    AC - Alternation
                    ________



                    -Reverse polarity or DCEP, electrode positive (REP) - has 10% more penetration than in AC application.

                    -Straight polarity or DCEN, electrode negative (SEN) - has the least penetration, welds better in thinner metal.

                    In direct current, electricity always flows from negative to positive. Just like when you turn on your garden hose and the water begins to flow, when you weld with DC, the current flows out of the negative and back into the positive. This makes for a smooth welding current.

                    In alternating current, the electricity flows back and forth from negative to positive and positive to negative on a sine wave. This makes an erratic flow for SMAW, producing more spatter and a more unstable current. I used AC for welding 6011 for a couple of years. The welds were OK, but give me DC anytime.

                    Direct current electrode positive (DCEP) is what we used to call reverse polarity. Direct current electrode negative (DCEN) is what we used to call straight polarity.

                    In DCEP the electricity flows into the tip of the welding rod and concentrates about two-thirds of the heat, which gives good penetration. DCEP is usually used on thicker steels.

                    In DCEN the electricity flows out of the rod, concentrating about one-third of the heat on the rod. Less penetration makes this a very good choice for thinner steels.
