arc welding,DCEP,DCRP

hi guysin arc welding with consumable electrod .in which DCEP or DCRP type we have more deep of diffusion?be happy.
Reply:Hello    What electrode are you using?  6010? 6011? 6013? 7014? 7018? 7024?  These are the most common.  If we know the number on the electrode then we can help you better.  Also, what is your welder machine?  AC or DC?  This will help also.  Brian  Sparkeee24

Reply:you are wright.I am amused with semi words.OK now :how I could correct my question?

Just a little humor there  .  Sorry, couldn't help it.  Here's they way the terms go; DCEN, Direct Current Electrode Negative is also known as DCSP or Direct Current Straight Polarity. That would be straight polarity waaayyyyy back when Studibaker autos and Ford tractors used positive ground and negative hot lead.  ; DCEP, Direct Current Electrode Positive is also known as DCRP or Direct Current Reverse Polarity. So to sum it up there is DCEN/DCSP as one polarity and DCEP/DCRP as the other and most common if you have a DC welder. For stick and stick only there is a very general rule of thumb that says DCEP is usually more penetration. But again that is a general statement and for stick only. It is not necessarily true for every scenario and not necessarily true for Wire Feed applications.Like Sparkee says, more specific information as to your application and he can give you a more specific explanation.
