Welding Pulse Monitor

The purpose is to further optimize my old analogue welder, welding current and welding wave forms when she has to weld thin aluminium sheets in butt-joint.

With my novice skill job of butt-joint with thin aluminium (like ones with 1.5mm thick) has been a tiny thorn in the throat. For one thing aluminium filler did not want to melt in to the starting welding pools when I have to weld both ends of the two sheets at several intervals, especially in welding this thinner alu sheets.

I know pros can do it better, but it's not about myself, so tried to find another way to make it better, and found one called the MIX-TIG, a way to generate alternative current for thinner aluminium while mixing some percentages of direct current to the aiming target.
Anyways this should be posted on another thread soon after this.

The composition is like this;

We need some handy oscilloscope one like this;
