Advantages
1. Stable machine structure upside and downside of electrodes apply the pressure mode with assistant stroke. The welding efficiency is much higher.
2. The transformer of welding machine adopts the special resistance welding machine, the silicon steel slice is featured of high magnetic: the inner water- cooled by force; stronger power and high duty ratio.
3. Controlled by micro-computer and can saved at most 16 sets of welding settings, which is quite convenient for different kinds of welding sheets.
4. Can widely used in nut, studs, traffic tools, household items, cars. And it can be welded low-carbon steel, stainless steel, coated steel, non-ferrous metal wire, sheet, pipe, etc.
Working Principle
Install the workpiece: the rear positioning block and the right positioning block are used as the reference positioning block. To adjust, the motor zero point needs to be corrected. Other positioning blocks can be adjusted close to the workpiece. The side floating positioning block clamps the framework of the workpiece and the panel together to avoid the displacement of the welding spot. (The manual clamping screw fixes the workpiece on the side floating positioning block).
Welding: after the start (automatic) switch is pressed, the program automatically controls the action of the equipment to complete the product until the stop button is pressed.
Electrode Finishing
The electrode tip must be kept smooth and clean. If the electrode is worn or the surface is damaged after a certain period of use, it can be smoothed with a copper wire brush, a high-quality fine file or sandpaper. The specific methods are as follows:
Place the fine grain flat file between the upper and lower electric levels, place the function selection knob at the "air valve" position, make the electrode clamp the file, turn the file back and forth in the horizontal direction, release the air valve and reset the upper electrode after the indirect contact surface of the two electrodes is smoothed;
Grind the contact surface of the electrode with fine sandpaper, so that the electrode and the workpiece can maintain good contact.
When electrode loss is serious, machine tools must be used for trimming.
