Both electrodes focus current at the same point to make a spot weld. Draw a high current for spot welding, according to the thickness and type of medal. Spot welding may require up to 90,000 amperes for thick pieces of aluminum. Maintain the current for a specific period of time.Weld times in spot welding can vary from 0.01 seconds to 0.63 seconds, depending on the metal thickness. Spot welding may be used on extremely thin pieces of metal, up to 1.25-inch metal plate.oth electrodes focus current at the same point to make a spot weld.

Have you seen the video above? If not, take a look now because it will help you as you go along in this instructable. A typical resistance Spot-Welder can range in price from about $200-$800, but with a little resourcefulness, and a bit of free time, you can make one like this for about $10 or less.Spot welders are used to fuse thin sheets of metal together.They are most likely used in the auto industry, as well as HVAC for welding metal ducting. There are a couple of videos you should see before starting on this project, because you may want some background on how the device works.ave you seen the video above?
