- Page 14 Program key setting arc is ignited. Arc ignition time is the time the arc ignition MMA (DC) current lasts. When in high current ignition mode, the arc ignition current is generally 1.5~3 times the welding current, and the arc ignition time is 0.02~0.05s. When in low current ignition mode, the arc ignition current is generally 0.2~0.5 times the welding current, and the arc ignition time is 0.02~0.1s.

- Page 16 Cleaning strength (100%*Tc/Tp): Generally, in AC welding, when taking the electrode as the anode, the current is called the cathode current. Its main function is to break up the oxidized layer of the work piece, and the cleaning strength is the percentage cathode current holding in the AC period.
