Lincoln Electric IM754 RED-D-ARC ZR-10 - Manual (Page 16)

WELDING PROCESS
STICK (CONSTANT CURRENT) WELDING
Connect welding cables to the "TO WORK” and
"ELECTRODE” studs. Start the engine. Set the
"Polarity” switch to the desired polarity. Set the
“RANGE” switch to a setting that is equal to or slightly
greater than the desired welding current. (The
“RANGE” dial marking indicates the maximum current
for that range). Fine adjustment of the welding current
is made by adjusting the output “CONTROL” or
remote control.
For best arc stability, use settings 5
through 10.
The ZR-10 can be used with a broad range of AC and
DC stick electrodes. See “Welding Tips 1” included
with the ZR-10 for electrodes within the rating of this
unit and recommended welding currents of each.
TIG (CONSTANT CURRENT) WELDING
The K930-1 TIG Module installed on a ZR-10 provides
high frequency and shielding gas control for AC and
DC GTAW (TIG) welding processes. The TIG Module
allows full range output control. Afterflow time is
adjustable from 0 to 55 seconds.
When using the ZR-10 for AC TIG welding of alu-
minum, the following settings and electrodes are
recommended:
The K930-1 TIG Module should be used with the ZR-
10 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-
onds.

BREAK-IN PERIOD
It is normal for any engine to use a greater amount of
oil until the break-in is accomplished. Check the oil
level twice a day during the break-in period (approxi-
mately 50 running hours).
IMPORTANT: IN ORDER TO ACCOMPLISH THIS
BREAK-IN, THE UNIT SHOULD BE
SUBJECTED TO MODERATE
LOADS, WITHIN THE RATING OF
THE MACHINE. AVOID LONG IDLE
RUNNING PERIODS. REMOVE
LOADS AND ALLOW ENGINE TO
COOL BEFORE SHUTDOWN.
The engine manufacturer’s recommendation for the
running time until the first oil change is as follows:
Refer to the Engine Owner’s Manual for more informa-
tion.
