It's a legal and safety thing, much more than it has anything to do with sales. Other owners do not have to follow those same rules. The other thing is also more of a "if you have to ask, you might not know enough to do this safely". Working with high energy electronics can be lethal. This is not the best kind of project to learn on, for that reason. Battery powered circuits are a lot more forgiving of mistakes. You might smoke a part or two, but other than a burned finger or two, it's not that dangerous. Something like a welder is not so forgiving. It has the one two punch of high voltage on the input and super high current on the output. It could kill you with no trouble at all. So while I'm all for people modding things and learning new skills, you need to learn basic safety before you dive in. It's not just wiring something up wrong, either. Because of the voltage and current involved, just routing one wire too close to another or crossing it at 90° can be a problem. High current will generate voltage in wires passing close by. This is how some of the parts in the welder operate. And obviously the machine is very capable of producing enough current to jump a gap, it's an arc welder after all, so how things are routed is very important.
The other big difference is that I didn't have to ask what would work, and made it very clear that I was voiding my warranty with this, and only discussed it after I had tested everything.

Also Mark didn't say that wouldn't interchange, he just didn't say it would. He really can't say anymore, but he did tell you that the schematic shows it as a 103 pot so he did more than he needed to. He also mentioned that it is part of a series parallel circuit with other resistors so it probably forms a ladder divider circuit. You can take it from there.
I understand and agree with all the points you bring up except for the fear on EverLast's part that they are fearful of a low-end model cannibalizing sales of "higher-priced" models which come with a way to control amps remotely. So far as liability issues, all they have to do is to state doing such is at the "owners" risk.

It is quite apparent the 140st is capable of remote amperage control and the cost to add the feature is virtually nil. To add a connector, the additionally wiring would probably run less than $2.00 if that in China.
Imagine how they would corner the market if it came setup from the get-go with a way to remotely control the amps, both in the short and LONG term.

Sales of 140st's would soar.
160's would drop a little.
Pedal sales would soar.
Persons buying into the low-end would put EverLast on their short list on who to buy from when it comes time to upgrade. As it is now lots of potential customers such as myself find it hard to buy into the EverLast brand if they Google around.
