Here is something different for the welding cart topic,,,
I have purchased several of these,, and cover my welders, plasma torch, and the pic is the cover for my CNC torch control.
Waterproof 600D Heavy Duty Boat Engine Hood Covers - Fit for Motor 115-225 HP
View attachment 794139
This cover is 600D fabric, which seems good for indoor use.
My CNC torch control sets on a plastic audio/video plastic cart that I had.
It is sturdy enough,,.
I hated worrying about the other shop projects getting dirt/dust. etc on the expensive electronics.
Sometimes the laptop is here, also, this cover will protect it also.
I have two welders, they both wear covers,, also.
These covers only cost $10 to $27,, cheap compared to constantly cleaning expensive equipment,,
