RECOMMENDED APPLICATIONS
WELDER
The WELDANPOWER 125 provides excellent constant
current DC welding output for stick (SMAW) welding
and DC TIG welding using the “scratch” starting tech-
nique. THE K903 TIG Module can be added as an
option to provide high frequency starting. For more
details on using the machine as a welder, see WELD-
ING OPERATION in the Operation section of this
manual.
GENERATOR
The WELDANPOWER 125 gives smooth AC generator
output for medium use, non-commercial demands.
For more details on operating the generator, see GEN-
ERATOR OPERATION in the Operation section of this
manual.
OPERATIONAL FEATURES AND
CONTROLS
The WELDANPOWER 125 was designed for simplicity.
Therefore, it has very few operating controls. A single
dial on the control panel lets you select either welder
or generator use. For welding, the same dial selects
continuous current output over the machine’s 50 to
125 amp range.
The 9 HP Briggs & Stratton gasoline engine controls
include a recoil starter, choke, throttle control, and
stop switch. See ENGINE OPERATION in the
Operation section of this manual for details about
starting, stopping, and breaking in the gasoline
engine.
DESIGN FEATURES AND
ADVANTAGES
• DC Stick welding (SMAW) process capability with
output range from 50 - 125 amps.
• Single-dial current output selection.
• Work and Electrode welding cable mounting termi-
nals.
• 4500 watts of continuous 115/230 volt, single-
phase AC auxiliary power (3500 watts CSA).
• Separate ground stud for safe connection of case to
earth ground. Single 20 amp, 230 volt generator
receptacle.
• Duplex 20 amp, 115 volt generator receptacle.
• Integrated generator output overload protection
through two 20 amp circuit breakers.
• Welded-tube, full roll cage frame protects engine
and generator/welder.
• Lightweight, portable design.
• Briggs & Stratton 9 HP Vanguard
®
overhead valve,
air-cooled gasoline engine.
• Rubber mounting isolates engine and generator
from frame to prevent machine “walking” during
use.
• Hour meter standard.
• Automatic shutdown for low oil condition.
WELDING CAPABILITY
The WELDANPOWER 125 is rated 125 amps, 25 volts
DC at 30% duty cycle on a ten-minute basis. This
means that you can load the welder to 125 amps for
three minutes out of every ten-minute period. The
machine is capable of higher duty cycles at lower out-
put currents. For example, you can load the welder to
100 amps for six minutes out of ten for a 60% duty
cycle.
The current is continuously variable from 50 to 125
amps DC. The WELDANPOWER 125 can, therefore,
weld with all 3/32 and most 1/8 inch diameter Lincoln
DC electrodes as well as do DC TIG welding.
LIMITATIONS
• The WELDANPOWER 125 is not recommended for
any processes besides those that are normally per-
formed using stick welding (SMAW) procedures or
TIG welding.
• The WELDANPOWER 125 is not recommended for
pipe thawing.
• During welding, generator power is limited to 100
watts, and output voltages can drop from 120 to 80
volts and 240 to 160 volts. Therefore, DO NOT
OPERATE ANY SENSITIVE ELECTRICAL EQUIP-
MENT WHILE YOU ARE WELDING.
