That is the way it works. It is not a defect. First, you have a entry level machine for 500.00 neighborhood. Anything close is well over 1000 in blue or red. We've sold thousands of those units like that, and while you call it a defect, it is a base model and operates as a base model. If you prefer something different, step up to the Power i-TIG units. If you want that kind of operation, you pay for it. Any base TIG unit like that like a Maxstar 150 did not even have a digital display. You just depended upon a relative position of the knob, which you can do with the 160STH as well. When you actually start welding, you will get the true output of the welder. If you want something that operates more to your liking by another brand, tryout the Miller Maxstart 161sth for 1700+.
Think about it: When you plug the foot pedal in, it is reading the position of the potentiometer on the pedal. As you step on the pedal, the amps will increase and the change will be reflected on the meter. The unit is still max controlled on the panel, through the relative position of the max power potentiometer. This unit is an analog inverter and it means that there are some sacrifices in functionality unless a lot more is paid. At any rate, you weld by what you see, feel and hear in the weld puddle, and not by an arbitrary amp number. Be assured the Maxstar base models won't weld any better than the analong entry level Everlast, but if you want the function, you have to pony up the funds to get that. Call it marketing, or whatever, but that's the way it is. We do not hide it. We actually mention it in the product notes here:
