Have you tried moving a little faster?

 

Yes and the bead will get lower. I'm just wondering which is the proper way to adjust.

 

Any pics? you might also need more voltage... is it easy to burn through if you slow down?? if no than up the voltage a tad

 

My intensions were to lay some beads but got working on my Vespa . Tomorrow I will lay some beads and post some.
As for buring through I'm referring to thicker metal like 1/8 but perhaps you may be thinking the same , if so no no burning through.

 

A good starting guide is set the volts where you think for the metal thickness. Then adjust the wire speed until you find the best setting. If too fast you will feel the wire hitting the metal If too slow the wire will burn off at the tip If it dosent get hot enough Set the volts higher and fine tune the wire speed again Its a good rough guide for a beginner.

 

Thats a bit too random when you can simply use the chart provided my the machine as a good start.

 

On that floor assembly you're doing, I'd pull if I was you. The last thing you need is a lot of penetration on something that thin. You'll still get a fine weld, but you'll alleviate the risk of burning through.

I think you're gonna get wavy gravy when you weld it, even if you stitch weld, and back step. I hope not. Try to go with the narrowest bead you can....that'll help to reduce the distortion.

 

I’m not the sharpest knife in the drawer, still trying to get the hang of what the difference is between push and pull, all I really understand is pull is suppose to be a stronger weld. Still got some practice welding to do on same gauge metal, I cut and cleaned some pieces up today. I tried some the other day with the inside panel settings and it seemed pretty good, good starting point any way.

 

Push is more penetration with MIG. You're running the gun ahead of the puddle into fresh metal. From right to left, the gun is at the left end of the puddle.

Pull welding is like stick welding...…...from left to right, the electrode is to the right of the puddle. With MIG, this makes for less penetration.....which is what you want in this circumstance.

 

Welllll sheesh here I was having a hard time understanding, duh just clicked in. So it’s all a matter of right to left or left to right. I can now take that part of welding off my bucket list. :cool2:

 

Of course this all depends on which hand you are holding the electrode/mig gun in....

 

I'm a righty so right hand
