When working, the two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes. When the welding current flows from one electrode through the other electrode, an instantaneous heat weld is formed at the two contact resistance points, and the welding current instantly flows from the other electrode along the two workpieces to this electrode to form a loop, and will not damage the internal structure of the welded workpiece.
[0003] When the existing air conditioner side panel spot welding machine is in use, because there is no structure designed on the spot welding machine to block the sparks generated when the spot welding machine is working, the sparks generated when the worker uses the spot welding machine will splash onto the worker's body and cause injury, making the use of the air conditioner side panel spot welding machine unsafe, so a new type of air conditioner side panel spot welding machine is needed.

Placement grooves 505 are provided on both inner walls of the rectangular groove 503, and the front end of the placement groove 505 is communicated with the front surface of the fixing block a501. A rotating bar 506, a rotating shaft 507 and a spring groove 509 are provided inside the placement groove 505, and the rotating bar 506 is rotated by the rotating shaft 507 and is located inside the placement groove 505. A spring groove 509 is provided on the inner wall of the placement groove 505, and a spring a510 is provided inside the spring groove 509, and one end of the spring a510 is fixed to the spring groove 509 by a bolt. The inner wall, the other end is fixed to the inner side of the rotating bar 506 by bolts, so as to better pull back the rotating bar 506. The two sides of the fixed block b504 are provided with card slots 508, so as to better limit the fixed block b504. The front end of the rotating bar 506 is located inside the card slot 508, and the rear end of the rotating bar 506 extends out of the front surface of the fixed block a501, so as to facilitate the rotation of the rotating bar 506. When the staff needs to block the sparks when using the spot welding machine, the user holds the two rotating bars 506. At this time, the rotating bar 506 rotates in the placement slot 505 through the rotating shaft 507, driving the spring a510 to be stretched. At this time, the user inserts the fixed block b504 at the bottom of the baffle 502 into the fixed block b504. The front end of the rotating bar 506 is rotated out of the slot 508 under the action of the rotating shaft 507. At this time, the fixed block b504 slides upward without hindrance.

[0024] Example 2
[0025] See also Figures 1 to 6 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that a slide groove 511 is opened on the top of the baffle 502, and a spring b512 and a telescopic block 513 are arranged inside the slide groove 511, which can better block the sparks generated during the processing and better enable the air conditioner side panel to move horizontally.
[0026] Specifically, a slide groove 511 is provided at the top of the baffle 502, and a spring b512 and a telescopic block 513 are provided inside the slide groove 511.

A symmetrical spring b512 is provided at the bottom of the telescopic block 513, which makes it easier for the telescopic block 513 to telescope in the slide groove 511. One end of the spring b512 is fixed to the inner wall of the slide groove 511 by bolts, and the other end is fixed to the bottom of the telescopic block 513 by bolts. A smooth steel sheet 514 is fixed on the top of the telescopic block 513, so that the material to be spot welded and the telescopic block 513 can be welded together. The top of the shrink block 513 reduces friction and makes movement more convenient. When the staff operates the spot welding machine, the air-conditioning side panel that needs to be spot welded is placed between the two smooth steel sheets 514. The sparks generated when the air-conditioning spot welding machine is working are blocked by the expansion block 513. Under the action of the spring b512, the top surface of the smooth steel sheet 514 is always in contact with the surface of the air-conditioning side panel that needs to be processed, which can better block the sparks generated during the processing. When the processed air-conditioning side panel needs to move horizontally, the smooth surface of the smooth steel sheet 514 makes the moving friction of the air-conditioning side panel between the smooth steel sheets 514 smaller, so the air-conditioning side panel can be better moved horizontally.
[0027] In this embodiment, preferably, a symmetrical protrusion is provided at the bottom end of the telescopic block 513 , and the protrusion is located inside the slide groove 511 to prevent the telescopic block 513 from falling off when telescoping in the slide groove 511 .
