This User's Guide manual provides
specific welder information for the 230
amp ac/140 amp dc arc welder. This
manual contains information such as the
specific assembly information, welder
duty cycle, welder open circuit voltage,
heat control adjustments, recommended
electrodes, etc. that are related to this
welder only. Table 1 lists the welder
specifications.
General welder information such as
safety information, general installation or
assembly instructions, preparation for
welding, general operation instructions
and welding techniques, etc are in the
WELDER'S INSTRUCTION MANUAL,
ARC WELDERS.
DO NOT ATTEMPT TO OPERATE
THIS WELDER until you have read and
understand both manuals. Make certain
you have removed all documentation
from the shipping carton.
Additional information on your welder is
available through the place of purchase
or from the manufacturer.
Read SAFETY SUMMARY in the
WELDER'S INSTRUCTION MANUAL,
ARC WELDERS before unpacking the
welder and before proceeding with any
procedures or making any attempts to
do any welding.
Table 1. Welder Specifications
230 amp ac/140 amp dc
DESCRIPTION: Arc Welder
INPUT: 230 Vac, 48 amp, 60 Hz, 10
ac High Output: 60-230 amps
ac Low Output: minimum-180 amps
dc Straight/Reverse 20-140 amps
MAX O. C. VOLTS: 72
DUTY CYCLE: 20% @ max. rated amperage
MODEL: 110-114
DUTY CYCLE
The duty cycle rating of a welder defines
how long the operator can weld and
how long the welder must be rested and
cooled. Duty cycle is expressed as a
percentage of 10 minutes and
represents the maximum welding time
allowed. The balance of the 10 minute
cycle is required for cooling. Your new
welder has a duty cycle rating of 20% at
maximum rated output at either output
tap.
SELECTING AC OR DC
WELDING
The proper type of welding current is
determined by the work that needs to be
done.
ALTERNATING CURRENT
WELDING
• Alternating current (ac) welding is
performed when the welding cables
are connected to the AC OUTPUT
jacks. This kind of welding current is
ideal for Heavy Plate (flat position)
welding.
This welder has three plug in AC
OUTPUTS and two DC OUTPUTS, on
the front of the welder. The ac jacks are
marked HIGH AMPERAGE, LOW
AMPERAGE, and GROUND. The dc
jacks are marked, POS and NEG.
Connect the electrode output cable to
the HIGH AMPERAGE jack for high
current (230 amp maximum), low
voltage ac operation or to the LOW
AMPERAGE jack for low current (180
amp maximum), high voltage ac
operation.
Most ac welding operations will be
performed using the LOW AMPERAGE
jack. This output tap, because it has a
higher open circuit voltage (OCV),
provides a deep penetrating arc for
welding rusty or thicker metals.
American Welding Society (AWS) rated
rods 6011 and 7018 type are formulated
to work well with the higher OCV of the
LOW AMPERAGE jack.
The HIGH AMPERAGE jack is better
suited for welding thinner pieces
because the OCV at this tap is much
lower. This tap delivers a shallow
penetrating arc and smooth, non-stick
welding, preferred for welding thinner
metals. AWS rated 6013 and 7014 type
rods work well at this tap, since they do
not require a very high open circuit
voltage to start.
a. LOW/180 amp. jack = Approx.
71.60CV
b. HIGH/230 amp. jack = Approx.
44.70CV
DIRECT CURRENT WELDING
Direct current (dc) welding is performed
when the welding cables are connected
to the DC OUTPUT receptacles. The
welder has two dc welding options,
straight polarity and reverse polarity
welding.
StraightPolarity
Straight polarity dc current flows from
the welding rod (negative) into the work
piece (positive). Straight polarity dc
welding is ideal for:
• Cutting Steel,
• Hardfacing work,
• Single Carbon Brazing,
• and Build up work for heavy deposits.
To weld with straight polarity dc, place
the electrode cable in the plug marked
NEG (negative) and the ground cable in
the plug marked POS (positive.).
Reverse Polarity
Reverse polarity dc current flows from
the work piece (negative) to the
electrode (positive). Reverse polarity dc
welding is ideal for:
Overhead welding.
Vertical Welding,
Cast iron Welding,
Heavy Aluminum Welding.
Rivet Welding,
Sheet Metal Welding,
Low Hydrogen Rod Welding,
and Arc Bronze Rod Welding.
To weld with reverse polarity dc, place
the electrode cable in the plug marked
POS (positive) and the ground cable in
the plug marked NEG (negative).
As you can see, most of the dc current
welding is done in the dc reverse
polarity mode of operation.
SETTING THE AMPERAGE
CONTROL
This welder has a unique OUTPUT
AMPERAGE SELECTION (current)
control lever for faster, more efficient
heat adjustments than plug in style,
clicker switch, and crank type designs
commonly used in other welders. The
OUTPUT AMPERAGE SELECTION
control provides amperage control
(current adjustment) for both, ac and dc
welding operations.
To reduce the amperage: Squeeze
the OUTPUT AMPERAGE SELECTION
control lever (on the front of the welder),
push in lightly, and push the lever
downward.
To raise the amperage: Squeeze the
OUTPUT AMPERAGE SELECTION
control lever (on the front of the welder),
pull out lightly, and move the lever
upward.
