A spot welder creates a minor weld on thin folio metal.
A resistence or spot welder sends electrical contemporary washed-up two pieces of leaf metal to construction a miniature weld. The electrical happening travels between two clamping electrodes. One electrode sends a abrogating charge and the other a complete charge. This generates heat in the conductive stage metal. The extent and power of the spot weld are dogged by the spot welder settings and the proportions of the electrode tips. An incorrect spot weld Testament not dominion leaf metal well-organized, and it is first-rate to comp the spot welder on scrap metal before spot welding finished stage metal.
Instructions
1. Depress the pedal of the spot welder to lower the top jaw of the spot welder and weld the sheet metal.9. Twist the welded sheet metal a quarter-turn before releasing the pedal to avoid pulling a welding electrode from its socket.10.
2. Establish the grasp, weld, squeeze and off-time of the spot welder by locating the thickness of the folio metal on the welding chart affixed to the spot welder.
3. Disinfected the tips of both the top and bottom electrode by sliding the file over each tip. To weld correctly, the tip of each electrode should have no black carbon deposits.
4. Put on your leather work gloves.
5. Turn on the spot welder and open the cold water supply valve to flow water through the electrodes.
6. Stack the two pieces of sheet metal on top of one another.
7. Set the stacked pieces of sheet metal on the bottom electrode of the spot welder.
8. Slide the chapter metal gauge onto one contour of the phase metal to halt the thickness of the metal. When the period metal fits snug in a chapter metal gauge slot, interpret the amount above the slot. This Testament expo the thickness of the metal.
Attempt to pull the sheet metal apart. If the metal bends rather than pulls apart, the spot welder is set correctly. If the spot weld breaks, increase the weld time of the spot welder and repeat the listed steps until you achieve a proper spot weld.
