Bad Creek Blacksmith Posted December 11, 2009 Share Posted December 11, 2009 Last night I was welding 1/4" x 1" mild steel with a 6011 rod, First time using this rod well on one weld the rod was glowing red. I would like some info on what was I doing wrong. I'm not a expert welder!!!! Quote Link to comment Share on other sites More sharing options...
HWooldridge Posted December 11, 2009 Share Posted December 11, 2009 What diameter rod were you using and at what current setting? Quote Link to comment Share on other sites More sharing options...
Dragons lair Posted December 11, 2009 Share Posted December 11, 2009 Yep sounds like too small and/or too hot. Ken Quote Link to comment Share on other sites More sharing options...
caleath Posted December 11, 2009 Share Posted December 11, 2009 yep too much current for the dia rod you are using. Quote Link to comment Share on other sites More sharing options...
Thomas Dean Posted December 11, 2009 Share Posted December 11, 2009 1/8"dia rod run around 95amps, tweek as needed. 3/32"dia rod run around 65amps, tweek as needed. The 3/32" rod will get hot faster and burn the flux off when you have used about 1/2 the rod. I HATE this size of 6011 for this purpose. You can use a 1/8 rod on this size material easy, actually I think it would be better to use the larger rod. Let us know how you make out.

Pipeliner32 Posted January 2, 2010 Share Posted January 2, 2010 To high of a current seems like Quote Link to comment Share on other sites More sharing options...
Dragons lair Posted January 2, 2010 Share Posted January 2, 2010 Just a note, welder are differant, Just cause it says 90 on the plug in or dial don;t mean that is exact amps. Also AC and DC rates are differant. Start low (on scrap) tweek till it burns good for the rod used. Keep notes. Had a neighbor stop at my welding shop. Wanted to know why his welds on his mowers wern't working. He was using 3/32 dc rod and got some 3/16 7018 AC running at the same amps.

Mainely,Bob Posted January 9, 2010 Share Posted January 9, 2010 It`s my understanding that 6011 was developed for AC machines.If you have a DC machine then 6010 is a better choice. Whatever supplier you get your rod from should have small handbooks that will give guidelines for appropriate size and type rod for a project.The same book will tell you approximate amperage and whether to run a DC rod either electrode positive or negative.Welding suppliers usually give these handbooks out for free or at little cost. Lincoln Electric also puts out a lot of low cost books related to all types of welding and welding projects. Quote Link to comment Share on other sites More sharing options...
