In the manual setup mode, the current and voltage are set independently. 12 Checks whether the protective atmosphere is used. 13 Sends the welding wire to the tip of the welding torch in non-welding status. 14 Selects a wire diameter. The SP option indicates a wire diameter not specified. 15 Selects a wire type. The SP option indicates a wire type not specified. 16 Performs operations in different welding modes (welding without ending arc, welding with ending arc, welding with repeated ending arc, 2T, 4T, special 4T, and spot welding). 17 Selects a welding method among the DC, single-pulse, and double-pulse welding methods. The SP1 and SP2 options are used for other welding methods. 18 Adjusts welding parameters, lock parameters, and internal menu parameters. Shenzhen Donrun Welding Equipment Co., Ltd.
