220V/110V Micro spot welding machine, battery spot welder dual pulse. Micro computer control + Dual pulse. This kind of spot welders are specially designed to meet the needs for the production of high-grade batteries (nickel-cadmium, nickel-hydrogen, lithium batteries).Single-chip microprocessor control is adopted to ensure higher stability and reliabilities in performance. Also a current loop was formed at the same time. These will not hurt internal structure of work piece. Height adjustment of Welding needles : loosing the height adjustment screw with a wrench. Then adjust or replace the length of needles exposed below the electrodeusually, it is about 15mm. It is easy to deform if it is too long finally, tightening screws. Width adjustment of Electrode (needles) : loosing the width adjusting screw with a wrench, then adjust two electrodes so that two needles to appropriate distance.
Test: test whether there is coke on the needles or not. You need to clear it with a file or abrasive paper. Then using the right foot press pedals. When its head drop, stare the welding needles until the needle is on the welding point. Power: put plug into a 220V power socket, and turn on the power switch, indicator flashing, the welder is work.
If working indicator does not shine or shine without flashing, turning off the power then turn on again. In order to ensure good quality of welding, you should often adjust needles and keep it in a good condition.
