Greetings,

With respect to wire feed speed, I had read (or misunderstood) that this should be adjusted first rather than power output. Unit is a Lincoln 125HD.

Many thanks and a safe and Happy New Year to everyone.

Best,

Lyman

Wire feed speed is your welding amperage.

The voltage needs to be high enough to weld properly at the set wire feed speed.

Too low of voltage and bead is narrow and rope like. Increasing voltage widens the puddle and flattens it.
Too much voltage spatters a lot.

However, if I need the full output of a low power machine, I often put the volts at max and then dial up the WFS to match it until it welds correctly.

"Wire feed speed is your welding amperage.". Can you elaborate a bit on that?

Thanks,

Here is a good article on the subject of CC/CV power sources and their applications.
