A spot welder joins two pieces of sheet metal by clamping them together with electrodes and passing an electrical current through the metal between the electrodes. Since the metal being welded has higher electrical resistance than the electrodes, it melts. The weld quickly cools after the electricity stops flowing because the electrodes are relatively cold.
You can see spot welds on cars. Look for dimples near the edge of two plates or panels. They are easier to spot on the undercarriage, inside the trunk and on some frame members especially where bodywork and trim doesn't hide them.

It's not so much the duty cycle you have to worry about but the current draw, 8 gauge wire is more than sufficient to hold the current draw of your spot welder.
How does a spot welder work?
A spot welder uses 2 electrodes positioned opposite each other. 2 pieces of metal (usually thin) are placed like a sandwich between the electrodes which come together with force and an electrical current is passed thru them which actually melts the pieces where they touch each other. This produces a small weld "spot" . This spot is about the same size as the tips of the electrodes.

How big of a generator do you need to drive a 200 amp welder?
When you refer to a 200 amp welder you are talking about the output side of the welder. What you have to do is find out what the input voltage and current of the welder is to calculate the size of a generator needed to operate the welder.
What is erection productivity of welder?
when working in the structural steel erection field as a welder,welding is going to be your task.Every employee has there separate task from my experience.Im guessing your question is what is the productivity requierment of a welder in the erection process.The productivity varies moving from one spot to the other and the distance in between can take time also set up, but to anwere your question plainly if you can weld 12 moment connections in a single day your doing good, and if you can blow through two splools of wire a day you are a very and i quote "very" productive welder.
Who is the first welder in the world?

Can you use Stick Welding machine for Spot Welding if yes how?
They sell a spot welding gun that plugs into a DC arc welder. If you have an AC225 or some other AC-only machine, this won't work. In general, tho, spot welders have their own power supplies so you don't need to reconfigure your stick welding machine for this.
