Notice
1. When building battery pack with Sunkko welders, if the home circuit system keeps
tripping, please replace your Circuit Air Breaker. For 110V version machine, the Circuit
Air Breaker in your circuit system should be higher than 40 A. For 220V version
machine, the Circuit Air Breaker in your circuit system should be higher than 30 A.
2. Please put on gloves and mask during your battery pack welding process to protect
yourself (Sparks may occur during welding process).
3. Unplug the welder when you are not using the welder.
4. During your welding process, the instantaneous large current generated by the welder
may cause the lighting equipment under the same power system flash and it is
considered normal.
5. Do not short circuits during spot welding or charging.
6. Do not use Sunkko welders with a voltage transformer as Sunkko welders are not
compatible with the common voltage transformers in the market.
7. Continuously spot weld too fast will speed up the loss of internal components of the
spot welder. We recommend that the time between each spot welding should be 3
seconds or longer.
