Wirespeed/voltage

[moe1942]

Yes, I should have started this post with " set up per door chart, then if..........






A poster on this board sent me an Email with his definition of this subject.

Wire speed = penetration

Voltage = bead height and width

Fine tune accordingly.

Until a better description comes along I will heed his advice.

Once I start Migging I will follow the advice of other experienced weldors. Practice!!

Thanks to all who contribute info. Makes the newbies (me) job easier.


Never too old to learn.

moe1942,

There should be a chart either on the drive door of your machine or in your manual that shows typical settings. In case it's missing, briefly:

.030 solid wire with CO2 - 40 to 145 amp welding range.

Welding current needed = 1 amp per .001" of metal thickness.

For .030 wire, set up at 2 IPM wire speed per amp of current desired.

Set the voltage to obtain a nice "bacon frying" sound when you weld.

Fine tune the sppeed and voltage for the best weld from that point.


Be well.
