When was the spot welder invented?
Spot welding is a form of resistance welding invented by Elihu Thompson in the late 1800s.
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.
What is the conductor size for a spot welder draw 90 amp with a duty cycle 40 percent?
To calculate the required conductor size for a spot welder drawing 90 amps with a 40% duty cycle, you need to account for the maximum current flow during operation. 90 amps * 1.5 = 135 amps (to accommodate the intermittent nature of spot welding). You would then use a conductor size based on a 135-amp current rating to ensure safety and efficiency in the electrical system.

What does a spot welder do?
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.
Is TIG Welder is also considered as Co2 welder?
No , although Co2 may be used , along with other gasses , a welder using this process is not considered a Co2 welder . TIG stands for tungsten Inert Gas , so the welder is considered / called a TIG Welder.
What is the size of a parallel parking spot in Oregon?

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?
The first welder is John Doe.
What is another name for the wire welder?
Another name for a wire welder is a MIG welder, which stands for Metal Inert Gas welding.
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.
