I've been using my Uptime160 MIG for a while now and it's working fine (slightly erratic welds recently but solved with a new tip).
After reading threads about voltage, amps and wire speed I decided to test the welder to see what the controls actually control and what the voltage is at the tip.
Wire speed control, this actually controls the wire speed - "0 to 10" doesn't relate to real numbers but almost perfectly linear increase in speed as dial is turned up. Noted the mm/second in a spreadsheet.
Current Control, marked 0 to 10, changes current on display from 0 to 160. Goes from won't weld a tin can up to melting thick stuff no problem.
Voltage at tip, 60v regardless of Current control.
lots of talk about "voltage should be about 18v for blahblah, should be 22v for anotherblah" etc.
So - the question:-
Are some welders variable voltage and some variable current, they are just different. OR is this one being fixed at 60v with adjustable current a bit of an oddity??
BTW - it also has a control for Inductance which doesn't seem to do much, any comments on that?
