  The two needles of the spot welding pen cannot be touch together, which will cause a short circuit and burn the machine. The DH30 is new to the market, the response to the DD2.0 was not very good, so a mini spot welder that can weld 0.1-0.15mm nickel pieces in up to 30（MAX) positions was introduce. It has a 0.91″ screen, which makes it very easy to visualize the power level etc. It is very convenient and quickDH30 Specifications:Screen: 0.91 Inch OLED

  Package size: 143x107x48mmSpot Welding Power Setting:Start with the first gear and increase the power slowly until it can be weld. Do not increase the power if it can be weld. Avoid MOS bombs. The black solder joints indicate that the power is too high.

  When welding, press down the soldering pin lightly, and the nickel sheet and the battery can be bond together. The harder you press, the less solid the welding will be. It will automatically trigger after pressing down for one second.
