Optional on some welder models
MIG welders equipped with gas are capable of welding with
0.024 (0.6mm) and 0.030 (0.8mm) solid steel wire on dc reverse
polarity and with 0.030 (0.8mm) self-shielding flux-core wire on
dc straight polarity. Larger, 0.035 inch (0.9mm) diameter solid
steel wire, on dc reverse polarity may also be used on this
welder. The use of larger diameter wire makes welding difficult
and the results cannot be guaranteed. The manufacturer does
not recommend the use of larger diameter wire.
WELDER OPERATING CHARACTERISTICS
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 the rated
output. This means that you can weld for two (2) minutes out of
10 with the remaining eight (8) minutes required for cooling.
(See Table 2).

INTERNAL THERMAL PROTECTION
Do not constantly exceed the duty cycle or damage to this
welder can result. If you exceed the duty cycle of your
welder, an internal thermal protector will open, shutting off
all welder functions except the cooling fan. If this happens,
DO NOT SHUT OFF THE WELDER. Leave the welder
turned on with the fan running. After cooling, the thermal
protector will automatically reset and the welder will
function normally again. However, you should wait at least
10 minutes after the thermal protector opens before
resuming welding. You must do this even if the thermal
protector resets itself before the 10 minutes is up or you
may experience less than specified duty cycle performance.
If you find that your welder will not weld for 2 minutes
without stopping, reduce the wire speed slightly and tune
the welder in at the lowest wire speed setting that still
produces a smooth arc. Welding with the wire speed set
too high causes excessive current draw and shortens the
duty cycle.

INSTALLATION
POWER SOURCE CONNECTION
POWER REQUIREMENTS
This welder is designed to operate on a properly grounded 120
Volt, 60 Hz, single-phase alternating current (ac) power source
fused with a 20 amp time-delayed fuse or circuit breaker. It is
Required

CAUTION
recommended that a qualified electrician verify the ACTUAL
VOLTAGE at the receptacle into which the welder will be
plugged and confirm that the receptacle is properly fused and
grounded. The use of the proper circuit size can eliminate
nuisance circuit breaker tripping when welding.
DO NOT OPERATE THIS WELDER if the ACTUAL power
source voltage is less than 105 Volts ac or greater than 132
Volts ac. Contact a qualified electrician if this problem exists.
Improper performance and/or damage to the welder will result if
operated on inadequate or excessive power.
CONNECT TO POWER SOURCE
WARNING
High voltage danger from power source! Consult a
qualified electrician for proper installation of receptacle at the
power source.
This welder must be grounded while in use to protect the
operator from electrical shock. If you are not sure if your outlet
is properly grounded, have it checked by a qualified electrician.
Do not cut off the grounding prong or alter the plug in any way
and do not use any adapters between the welder's power cord
and the power source receptacle.
Make sure the POWER switch is OFF then connect your
welder's power cord to a properly grounded 120 Vac, 60 Hz,
single phase, 20 amp power source.
EXTENSION CORDS
For optimum welder performance, an extension cord should not
be used unless absolutely necessary. If necessary, care must
be taken in selecting an extension cord appropriate for use with
your specific welder.
Select a properly grounded extension cord that will mate directly
with the ac power source receptacle and the welder power cord
without the use of adapters. Make certain that the extension is
properly wired and in good electrical condition.
Extension cords must be at the smallest a #12 gauge cord. Do
not use an extension cord over 25 ft. in length.
ASSEMBLING THE WELDER
The following procedures describe the process required to
assemble, install, maintain, and prepare to weld with your new
wire feed welder.
UNPACKING THE WELDER
1. Remove any cartons or bags containing parts/accessories.
2. Open the cartons or bags packed with your welder and
inspect their contents for damage. Report any missing or
damaged items immediately.
3. Grasp the top handle of the welder and lift the welder out of
the carton.
INSTALL THE GROUND CLAMP
Connect the ground clamp to the ground cable (coming out the
front of the welder) according to the instructions packaged with
the ground clamp.
INSTALL THE TANK TRAY AND BRACKET
Optional on some welder models
The tank tray bracket is installed on the back of the welder, see
Figure 1.
