Apr 27, 2007 · DCEN increases heat transfer to the material and is better for deeper welds It seemed to me that there was a mix up. EP for solid MIG wire but EP for shallow welds? What? Then it occurred to me that the "electrode" in MIG welding is actually your wire. If you have electrode positive, you are transferring the electron plasma to the electrode, i ...

Feb 26, 2008 · With DCEN and TIG, the electrons flow from the tungsten electrode to the base metal. It is the impact of the electrons with the base metal, and transfer of kinetic energy, that is primarily responsible for heating and melting the base metal.

Jul 2, 2011 · I've been trying to find the real difference between DCEN and DCEP stick welding. I've googled and read about 4 different sources, and half conflict with the other half. For example, half of them had said that DCEN Puts 2/3 of the heat in the electrode, and 1/3 in the work, but the other half said the exact opposite, that its 1/3 in the work ...

May 15, 2022 · In TIG welding, where the electrode is not consumed, DCEN is used and about 67% of the arc heat (and consequent penetration) is delivered to the work piece via a stream of electrons. If the polarity is reversed (DCEP), the electrode gets very hot and the work is bombarded by a stream of positive Ions causing cathodic etching (cleaning).

Oct 25, 2011 · - DCEN I will give more details on the last two in this post. First off I decided to not add a capacitor. I felt that a bridge rectifier and choke would get me close enough to a usable welder without breaking the bank. These are the parts that I used: - MDS150A 3-Phase Diode Bridge Rectifier 150A Amp 1600V

Mar 17, 2011 · With GTAW/DCEN, the flow of electrons from the electrode to the work, and the impact of the electrons with the work, produces the majority of the heating to produce the weld. If you've ever tried GTAW/DCEP, you know that the majority of the heat occurs at the electrode.

Aug 21, 2019 · Running low-hydrogen rods on DCEN for open root is quite normal here in Europe. DCEN on SMAW puts less heat in the base metal so it's easier to control the keyhole and not blow through. 7018 is a difficult rod to run on DCEN for open root, 7016 on DCEN makes it a lot easier because the puddle is less fluid (a bit more fast freeze).

Feb 19, 2014 · I've played with it some. 1st picture is with my Dynasty on DCEN with 100% helium, 2nd , and 3rd picture with my V350-Pro, and Tig rig no pedal, 4th picture with a friends Longevity Stickweld 250, my Tig rig no pedal. With out a pedal only way to control the heat is move faster. The welds made with the Tig rig on 10-GA were made at 50-amps.

Apr 30, 2013 · Re: 6013 dcen as ever lads i really appreciate your comments, this is my take on 2 g tig . i burn at 140 amps 2.5 wire, this gives an almost instant pool which i control by circling the tungsten between the top and bottom root edges, the circle is anti clockwise, the wire i pull in a dipping motion from the inside out, with a 4mm gap . im sure ...

May 22, 2016 · For 'small' wire feed welders (small in amperage output and small as in the maximum wire spool diameter that they can fit on the drive system), Lincoln NR211-MP or the Hobart Fabshield21B FCAW wires (that are made to run DCEN, so run them that way) in 0.035" wire diameter on 4" spools (2 pounds of wire) or 8" spools (10 pounds of wire) are your ...
