I've got a Lincoln AC/DC 225V/125V stick welder.  I'm using mostly 7018 and 6013 electrodes in the middle of the recommended Amp range.  I've been practicing my welds - started my project last night.  I'm building rock sliders for my Cruiser....   anyway, one of the most annoying things about my beads is their inconsistency.   Most times, I'll start with a nice uniform bead and then somewhere in the middle I'll get an empty hole with a slag crater in it...  what am I doing to get that hole in the middle of most of my welds?Thanks - if needed I can post pics.James

Reply:[QUOTE=prop-doctor;545530]sounds like your to fast and not holding arc length steady.../QUOTE]Yeah... likely that's the case - still haven't found that perfect position for my hands to move freely without jerking the electrode along at some point.   I bet that crater forms each time my hand skips a little, instead of gliding along.   Next time I get that I'll post the settings along with some pics.

Reply:You can also cut your electrodes in half to start out, until you get more comfortable. I just started trying to stick weld at the beginning of this year, after having a MIG for several years.Lincoln Idealarc 250 (circa 1962)Lincoln Weldpak 155 w/Mig KitLincoln Squarewave TIG 175

Reply:I had to force myself to slow down. MIG lays down much faster than stick. Like everything worth doing, it takes practice.Lincoln Idealarc 250 (circa 1962)Lincoln Weldpak 155 w/Mig KitLincoln Squarewave TIG 175

Reply:Remember, if you are wearing good gloves you can support a new electrode with a finger while you get things rolling then ease your finger away from it as the pain becomes unbearable Seriously, with new 1/16" electrodes you really have to support them at first because they vibrate if you breathe on them.  Even with new 1/8" I'll lay it on a finger of my off hand to keep it steady - just be aware that they heat up and will burn through a glove if you leave it touching too long.Hobart LX235Victor 250 Oxy-Acetylene Rig (welding and cutting)Bobcat 773F-350, 1999, 4x4, 16' 10K# trailerOutdoor Wood Burner - 10 cords/year

Reply:Your slag crater is odd. With pictures we'd definitely be able to help you further. But be happy you're learning stick first. It'll make GMAW and FCAW a cakewalk. A couple quick pointers that you may not have heard, pay attention to how your whole body is oriented before starting and then where it'll be when you've run out of electrode. Like someone else said, trace your bead out before actually welding. With time you'll know where you tend to get bound up and how to fix it. Most importantly is to watch the PUDDLE. I put that in caps because the tendency to to focus on the pretty light (the arc). That puddle will tell you almost everything you need to know. The tricky part is what your reactionary move must be to correct the problems. Have faith brother... You'll get it. Sometimes you just have to step away.And... If your weld is pretty, leave it out for the world to see. Otherwise grind it down and reweld until you get it pretty enough to showcase.Good luck!Marc
