Resistance or spot welding is different from arc or TIG welding. Spot welding usually means having electrodes in contact with the surfaces of the work piece(s), while arc or TIG means an arc passes through a gas in a gap between the work piece(s) and welding electrode. In TIG, an inert gas is applied around the electrode.abdulbadii said:TL;DR Summary: How do we do resistance ie. spot weld by use of arc/TIG welder

Resistance welding is a welding process that joins two or more pieces of metal together by applying pressure and passing an electric current through them. This causes the metal to heat up and melt, creating a strong bond between the pieces.
In resistance welding using an arc/TIG welder, two metal pieces are placed in contact with each other and an electrode is used to create an electric arc between them. The heat generated by the arc melts the metal and forms a weld between the two pieces.
An arc/TIG welder allows for precise control of the welding process, making it ideal for spot welding. It also produces clean, strong welds and can be used on a variety of metals, including stainless steel, aluminum, and copper.
It is important to wear proper protective gear, such as a welding helmet, gloves, and apron, to protect yourself from sparks and UV rays. Make sure the work area is well-ventilated and keep a fire extinguisher nearby. Also, ensure that the welding machine is properly grounded to prevent electric shock.
No, an arc/TIG welder is only suitable for spot welding. For other types of resistance welding, such as seam welding or projection welding, specialized equipment is required.
