10. WELDING OPERATION (continued)
10.2 AC pulse welding
For AC pulse welding, set the PROGRM switch to 21-23(wave pulse), 41-43(pulsed MIG or
aluminum), 61-64(pulsed MIG or stainless steel), and 81-84(pulsed MIG or soft steel). Even
when welding extremely thin plates or couplers, high quality welding can be obtained, because
input heat can be controlled while welding to match the ratio of EP current (torch with positive
polarity current) and EN current (torch with negative polarity current).

10.3 Adjusting penetration
The amount of penetration can be adjusted by changing EN current time during AC pulse
welding. Adjust the voltage exactly after adjusting pulse arc due to the slight change of
welding. In this case, the melting amount of wire will not change, unless current settings are
always the same. Refer to the manual of a robot control device.
