FCAW Stickout

I'm trying to focus on FCAW techniques to improve my welding skills.  I have a Hobart 125EZ.  I like the machine, but will eventually move up to a real MIG setup.What's a good stickout distance on .030 fluxcore? I've read 1/4 to 1/2, and I've read 3/4 to 1".   Does the stickout change for different types of welds?  Different thicknesses of metal?  I've read that dragging the  puddle is the recommended method for FCAW.  Do you think that's true?I've improved a lot just by reading, and by really focusing on what my results are.  But I have a ways to go still.  Thanks in advance.  You guys that do this for a living have my respect.
Reply:Split the difference and keep the stick out at 3/8. It is important to keep the distance consistent since it will vary the voltage and mig is all about constant voltage. Bigger mig machines may require longer stickout but worry about it later. Dragging would be the recommended method. Continue searching for info, a good welder is always looking to improve his skills and knowledge.
Reply:With your machine capping out at 125 amps you won't have a lot of room to roam around in anyway. Pretty much find the sweet spot and stay with that. Keep in mind there is the tip to work piece stickout and there's the tip to puddle stick out. One might be mentioned in one text and the other mentioned in the next tutorial you read. With that little machine you'll probably run about 1/2" plus a tad from the tip to work piece intially then try for keeping the tip about a quarter off the puddle. Maybe pull back if it seems too close. Watch for clues when you let off the trigger and look at the what's left. For the lower amps you can run the preheat right up close to the tip but not quite in the tip. The preheat will be that little section of blackened wire. Just a guess but I'd think you'd want about 5/16ths when you let off the trigger with about two thirds of that being preheat. Most of the T-GS wires are pretty dern forgiving so anywhere in there is fine. Don't get all hung up on it with that machine, if it hisses while you're running a bead and leaves some nice soft slag you're good to go. Go by the sound and bead appearance, measure the stickout after .."The things that will destroy America are prosperity at any price, peace at any price, safety first instead of duty first, the love of soft living and the get rich quick theory of life." -Theodore Roosevelt
Reply:Thanks to both, very helpful responses.  The stickout doesn't change depending on metal thickness?  If I'm burning through would it help to pull back a little?  That would lower the amps?  Again, thanks.
Reply:Changing your stickout is the wrong way to make an adjustment, remember its about constant volts. If your burning through read the owner's manual as it may have a reference of what settings are recommended for what thickness, since you will have adj your machine.
