Here's tonight's latest attempt 3/32nd 7018 at 90 amps.

So here's this mornings run of 3/32nd 7018 at 85 amps.
I still can't get a flat bead what should I be doing differently?

My latest attempt at 6010 and 7018 weaves.

Yea you can use the EVO 380, just make sure you have the blade for mild steel. You also need "rolocs", or something similar to do the polishing steps. I use 2" flap disc 40grit to remove the saw/blade lines first (go 90° to the lines as best as possible will work fastest) then maroon...

Sorry I forgot to say welds on mild steel.

Anyone use an Evolution 380 to cut welds? Do you need a different blade?

I don't have a band saw, my alternatives are a regular 14" abrasion disk chop saw and cut off disks on an angle grinder.

I'm interested in cutting and etching.

On the arc length, 6010/6011 like tight arc length, 7018 like a little longer arc length. At least that’s what I’ve found

Okay noted, thank you.

The very round and flat ripples and cold shoulders indicate too slow travel speeds. With the 6010, try to make your circles about a 1/4” wide Here's three fresh 6010 beads. 80 amps 1/4in circles Mostly 5-10 degrees lead angle. Tighter arc And faster travel speed. Thoughts?

The “toe” is the very edge where the weld meets the base metal. It should flow into the base metal almost seamlessly. Yours have almost right angles on them. You have the basic idea but need more practice. Understanding the fundamentals and practice practice practice. Wayne Okay awesome thank you. ...

I understand high center but can you explain what a cold toe is please?

Okay. I'll try that.
Currently I just do straight drag, except for the weaving.

Really longer on the 7018 eh, I was trying to get as short of an arc as I could.
What is it on the finished weld that indicates that I should change angle and arc length?

3/32nd 7018
1/8th 6010

On those 7018 beads I was running 95 amps.
The 6010 was 75 to 85 amps.

Looking for some feedback on these beads. The beads underneath are my attempt at 6010 weaves, next time I do some more 6010 weaves I'll post a picture as I really struggle with doing that well. https://uploads.tapatalk-cdn.com/20200104/5d543f3aa0e117d6fbf004246b1406c6.jpg Sent from my SM-G960W using...

Here are the photos of the finished bench grinder stand, same design just different height and bolt hole pattern. https://uploads.tapatalk-cdn.com/20200104/6acb0344d6cadff45aa50f04c6db0a30.jpg https://uploads.tapatalk-cdn.com/20200104/cbfbf4a88c9d4f7cfd5c705b3329fd6b.jpg Sent from my SM-G960W using ...

All mig, I setup for the thickness of the bottom of the rotor.
I made a second stand for a used bench grinder but the rotor was below freezing when I welded it so lots of cracks showed up in the weld. Lesson learned.

Before and after paint, a bench vise stand. At the time I didn't have a work bench to mount my new vise on. https://uploads.tapatalk-cdn.com/20200104/45a49c81bb947bbcd3ab8939db217fa7.jpg https://uploads.tapatalk-cdn.com/20200104/7d733b214b30acee53a23697a421ac12.jpg https://uploads.tapatalk-cdn.com/2...

Hello all, here's what I got.
