D. Current is not stable when machine is being operated
：
It has something with factors as following:
1. The power net voltage has been changed.
2. There is harmful interference from power net or other equipment.
E. Serious splashing in MMA welding:
May be the welding current is too big, while the electrode diameter is too small;
