My arc cuts into the piece a little much for my liking. I’ve tried many variations to the settings, try to slow it down and increasing the angle and lead-in but it still happens. All consumables are new, and otherwise it is making very clean cuts.
Any ideas on how to minimize this?
Miller 375 Extreme, 30A, 60IPM
Lead-In Radius: 0.1 in
Sweep Angle: 60 degrees
Lead In Distance: 0.07 - 0.1
Pierce Clearance: .08
Pierce delay? I assume you nibble is near the pierce point?
Is the 1/8"
0.5 sec, 1/8 inch
Yeah, its where it comes into the part from the pierce. The rest of the cut will be pretty smooth.
Use lead out perhaps?
Never mind. I see you said ‘initial’ travel.
Most often is the case that the nib occurs when the arc extinguishes, i would recommend using a decent leadout. Bear in mind that it’s challening to get rid of, especially on thin material.
Ok, I will try extending the lead out.
I understand that it wont be perfect, but it still seems a bit too much to me.
1/8" is considered thin material?
How much lead out was used in those parts in the pictures?
Actually it appears I had it set to zero. I was still following the instructions on the Langmuire videos.
