Hi all! First post here. I have been to a couple of trailer builders lately and watched them running vertical down in mig. They were using 70S-6 .035 wire with 75/25 gas at 27 volts and a wire speed of 660! My question, wouldn't this be WAY too fast to get penetration especially in the neck of the trailer where all of the stress is located? I would think you would want to run at 21 volts and around 300 on the wfs.

Yup, yup and yup. I made trailers for 8 or 9 years and ran downhills on goosenecks. Can't tell you the voltage or wire speed that was way before all the fancy stuff of the new welders. But they held and are still holding some being 40 years old...BobBob Wright -
Except for the gas ratio.... sounds like spray arc settings... doesn't it...???,,,,
If it was 80/20 or greater Argon..ratio....you could spray with it.....like.. 90/10...95/05...Last edited by H80N; 11-23-2016, 06:53 PM..

Exactly. But you don't spray on vertical welds, right?Originally posted by H80N View PostExcept for the gas ratio.... sounds like spray arc settings... doesn't it...???,,,,

I don't do much spray.... but I have been told that there are some cases where you can spray vertical down...........Originally posted by Edman9898 View Post.
