Wire Feed Welding Processes
(Constant Voltage)
The only Innershield ® electrode recommended for use
with the ZR-8 is NR ® -211-MP. The electrode sizes
and welding ranges that can be used with the ZR-8
are shown in the following table:
Diameter Wire Speed Approximate
(in.) Range In./Min. Current Range
.035 80 - 110 75A to 120A
.045 70 - 130 120A to 170A
.068 40 - 90 125A to 210A
The ZR-8 is recommended for limited “MIG” welding
(GMAW - gas metal arc welding). The recommended
electrodes are .030” and .035” L-50 and L-56. They
must be used with a blended shielding gas such as
C25 (75% Argon - 25% CO
2
). The welding ranges
that can be used with the ZR-8 are shown in the fol-
lowing table:
Diameter Wire Speed Approximate
(in.) Range In./Min. Current Range
.030 80 - 110 75A to 120A
.035 70 - 130 120A to 170A

NOTE: Output Control
must be set above “3”.
WIRE FEED, LN-7 WITH Yes HIGH Cold Press gun trigger,
K240 CONTACTOR KIT contactor closes. Welding
starts immediately.
The K930-1 TIG Module should be used with the ZR-
8 on high idle to maintain satisfactory operation. It can
be used in the AUTO position but the delay going to
flow idle after welding is ceased will be increased if
the AFTERFLOW CONTROL is set above 10 sec-
