Amperage 1-10

[Krod1218]

Welded on a new machine today and th e amperage knob had 1 through ten on it. How do I know exactly what amperage em I at. I kept it at 4 that burned pretty well.but I will still like to know what the numbers actually mean.

What make & model....???

Many times 1-10 is 10-100 percent output

Many times 1-10 is 10-100 percent output

each point represents %10 of the range selected

[Krod1218]

So what would that be? 40% off 250 =100

So what would that be? 40% off 250 =100

That would be correct IF the range is 0-250....

it depends on the machine you are using

I've got to go look at my 2005 model. I remember a range selector, then a fine tuning knob with actual amps on it. Some instructions are there suggesting best performance with range selector low, and fine tuning knob set high. I believe you add the numbers.

I dug out my manual. Set the range. Setting the right knob is 10-100% of the range you've chosen. The middle range for stick work is 80 amps wide. 8 being 80%, 80% of 80 amps is 64 amps. Add 64 to the low end of the range of 60. Amperage would be 124, a good heat for a 1/8" 7018 electrode. Mine stays close to there most of the time.

So let me get this right if I set the knob on the number 8 the amperage is at about 124??? Wow! I had it set on 3 1/2 -4 so that would be half of that. How is it possible to stick weld 7018 1/8 rods at 62 amps?

[WillieB]

if on the mid range, you were 60+30. The low end of the range and .375 times the 80 amps in the range. Still a cold weld.
