2Tapped Reactor AC-Z And Slope Coils

Tapped reactor AC-Z is factory con- nected to slope tap 8 which is suit- able for most GMAW applications.

AC-Z controls the inductance applied to the weld current. To increase inductance and wet out the weld puddle, connect to a higher tap number. To stiffen the weld puddle, connect to a lower tap num- ber.

3Leads 70, 71 and 72 With Pressure Connectors

Slide pressure connectors onto the same tap of each coil, and secure them.

YAn unbalanced secondary current can damage the main transformer and cause errat- ic weld conditions. Be sure leads 70, 71 and 72 are con-

nected to the same numbered slope turn tap on each coil. See slope connection label .
