In this article we will consider how to make spot welding do it yourself. Resistance welding can be purchased from $ 200, the master made his machine for $ 10.
For the manufacture of the apparatus, the master-master needed the following
Tools and materials:
-Transformer;
-Roulette;
-A circular saw;
-Boards;
-Pencil;
-Miter saw;
- Electric jigsaw;
-Drill;
-Grinder;
-Aerosol spray can with paint;
-Wire;
-Copper bus;
-Copper contacts;
- End;
-Nippers;
-Switch;
-Screwdriver;
-Fasteners;
-A pen;
-Nails;
-Elastic;
Step One: The Case
The master made the case out of the board. Measured the dimensions of the transformer. I cut the boards of the right size. For leverage used bars.
The upper arm makes a cutout at an angle. In the end cover makes cutouts for the switch and wire. Then it polishes and paints parts of the apparatus.
Step Two: Electrodes
It cuts about 2.5 cm of the copper bar and fastens it in the holders.
Step Three: Build
Installs a switch on the end cover.
The transformer was made by a master from a microwave transformer. The master has another article about its manufacture, also information on transformer alterations can be found on the network.
Secures the transformer. Connects the primary winding through two switches. One switch is mounted on the end cap, the second will be mounted on the upper arm.
Covers the housing with covers.
Sets the levers. holders and switches are attached to the levers. Connects the outputs of the secondary winding to the holders. The upper lever is "spring-loaded" with rubber bands attached to one end on the lever, the second on the body.
The spot welding machine is ready.
As the electrodes wear, they are easy to replace with new ones.
The whole process of manufacturing the device can be seen in the video.
