Heys guys first time poster here but i have been welding for a little while now... i got pretty good at it but i haven't done anything with it for a while... i am making a new welding cart and for some reason now my welding sucks they are strong but they aren't as good as i used to weld... have a lost my touch or is there some things i am not doing... i hold the torch at roughly a 45* angle to my work i have my shielding gas set at around 5psi and a good ground... my welds pop and get that honey comb effect what can i do to ? thanks in advance for the help
Reply:Change your gun angle to about 20 degrees vs the 45 you mentioned.Increase your covering gas flow to about 15 CFH.  If you're welding in a still environment you can try reducing gas flow by about 2 CFH til you start to see porosity in your welds.  Then go back up about 2 CFH and you're set.Hope this helps.Syncro 250 DX Dynasty 200 DXMM 251 w/30A SG XMT 304 w/714 Feeder & Optima PulserHH187Dialarc 250 AC/DCHypertherm PM 1250Smith, Harris, Victor O/ASmith and Thermco Gas MixersAccess to a full fab shop with CNC Plasma, Water Jet, etc.
Reply:you gotta turn the gas upI like to party!
Reply:What kind of wire are you using?  Cheap, chinese, no name, probably coat hanger wire from the swap meet?  Definately too low gas flow.  I run mine around 20 cfh and its just fine.  Just finished welding new ape hanger type handlebars to my bicycle.Ps what kind of gas is that?  They almost gave me helium (for steel) one time.
Reply:I run 75/25 AR/CO at 5 cfh with no problems indoors. Any breeze at all will cause the porosity. Dirty base metal or wire will cause it too, as will bad (contaminated or incorrect) shielding gas.The difference between art and craft is the quality of the workmanship. I am an artist.
Reply:Need need more gas. I run anywhere from 20 to 30 cfm. What welder are you using and pic's would help.Miller DVI2Lincoln Precision Tig 225Thermodynamics Cutmaster 38Everything else needed.
