Setting wire speed on a flux core welder without a chart
Posted: Wed Jul 29, 2020 6:22 pm
I am new to this forum and new to welding. Great site with great information.
I have been watching the MIG basics videos from Welding Tips and Tricks. I found the video on setting wire speed and voltage very useful. In particular, I thought that the short circuit MIG wire feed chart and calculations was great. Would this chart and calculations work with FCAW?
From the website and the videos:
"Based on the 1 amp per 1 thousandths of thickness of the metal being welded, there is a number that can be used for all the popular wire diameters that will give you a good starting point for wire speed.
For .045" wire the number is 1
For .035" wire the number is 1.6
for .030" it's 2
.023/.024" the number is 3.5
So the example giving is 1/8" or .125" thick steel.
For .030 wire, 125 x 2 = 250 ipm."
If this does not work for FCAW, is there a chart and calculation similar for flux core?
Thanks,
Trey
