A big part of successful spot welding is ensuring the contact pressure is repeatable. A great deal of effort is put into this because it really matters. This system has zero provision for this important aspect.

The welds will either properly weld, explode, or not stick at all, depending on the contact pressure. It isn't simply touching the surface using random force and turning on the current. When you are building a pack, you make _hundreds_ of welds, and every single one of them has to work.

 Kind of like a child's "Easy Bake Oven" version of a spot welder, sad to say.

 I guess you get what you pay for....
