Page 22: Sub-Menu
4-4 Sub-menu In order to achieve an optimum welding result, it is necessary in some cases to make corrections of the arc-length, arc force as well as parameters like pre gas flow time, post-gas time and slow wire feeding. For details of how to set the Sub-menu parameters, please refer to “Sub-menu parameter set”.
Page 23 Note! P11-P14 is available on double pulse function; P20-P21 is available on twin wire welding mode. - P01 Burn back time If too long time, the wire will burn back too much with too large melting ball at the end of wire; if too short time,the wire will stick with the workpiece.
Page 24 The double pulse welding is added modulated by low frequency pulse and the low frequency pulse between 0.5-5.0 Hz. Compared with single pulse, double pulse has more advantages: no need to swing, welding seam become fish-scaly automatically, the depth and density of the fish-scale welding seam is adjustable;...
