I need a bit of help in direction. I have a single phase 110/220v 200amp acdc sqaurewave inverter welder.

Specs Output Power

AC/DC

Input Voltages

110/220V ± 15%, 1-PH, 50/60Hz

Input Current

15A @110V, 30A @220V

Output Current

TIG: 10 – 200A AC/DC

Stick: 30 – 200A AC/DC

Power Factor

0.73

Power Efficiency

80%

Duty cycle @ 40°C (104°F)

60% @150A, 110V

100% @110A, 110V

60% @190A, 220V 100% @150A, 220V

I am going to buy a external welder frequency controller for it but help I need is how can I make a external box that can convert squarewave into sine, soft and triangle with turn of rotary switch? Doesn't need by a masterful product only work. Controller needs be able change waveforms and add adjustable pulse setting to welder. Goal is to either hard wire into welder between welder and output connector or inline between welder output connector and tig torch. I ain't an electronic genius as I need got into it but I did teach myself how to build guitar pickups and can make the. Sound how I want and can wire up a decently complex guitar configuration so with direction and guidance I can accomplish this as well. I did alot of Google but found nothing available as a diy project or commercial available

ive seen waveform generators for various electronics engineering applications. not sure ive seen a waveform converter taking a square input waveform and outputting a newly selected waveform. maybe @stupidbird has a suggestion

He's basically asking for a soak. In audio terms, that's a box that controls the volume after you add your effects and amplify it. The issue is you're controlling lots of power instead of a few mW at the preamp.

What would be wanted here is to modify the output wave before it's sent into it's final power stage. Doing this at the end is going to be expensive and require more engineering that I could give you, assuming the devices to do it even really exist.
