Ran some more beads

[RussellH]

With 10 mins of welding time under my belt I ran some more beads this morning

I tried the basic drag motion and the circular motion - for that 'stacked dimes' look but I don't think it worked very well

At one time I tried turning the voltage and WFS down just for fun and it immediately blew a hole in the metal...I thought this would produce less heat if anything ? I left the voltage alone and turned up the WFS from 50 to 70 and that worked a bit better. Can anyone explain to me the relation betweek voltage setting and WFS and what they do ? In other words when do you increase or decrease them ?

Please feel free to comment on the beads as far as what I'm doing wrong and if you have any suggestions for fixing it.

Here's a pic that shows two beads, the top one was a drag motion and the bottom was circular motion.

The details:

MM175
16 guage sheet metal
.23 Hobart wire
Mostly door chart settings

Here's the back side of the plate showing the two welds above. Too much heat ? amps ?

One more bead to show you guys

When you ran the bottom bead and did the circular motion, were you pulling the gun still or pushing? I'm a newbie also but I've found that if I push and do the circular motion I get better looking welds than if I pull (by better looking I mean flatter or with deeper penetration).

[RussellH]

That's a good question. I think the gun was more or less perpendicular with maybe a slight push angle to it.

I really need to understand the basics of adjusting the voltage and wfs values and keep practicing. Small 16 ga sheets @ $6 a pc are sure going to get expensive after I burn through a few of them a week

You "push" solid wire,...."Pull" fluxcore.
