What would the approximate amperage setting be if a welder were set to the high range 150 to 350 amps and tha final adjustment knob were pointing at 5 on a 10 point scale?

If the welder is set to the high range of 150 to 350 amps and the final adjustment knob is pointing at 5 on a 10-point scale, the approximate amperage setting would be around the midpoint of the range. This would suggest an amperage of about 250 amps, as 5 on a 10-point scale typically represents 50% of the maximum range.
