WELDER SPECIFICATIONS
DESCRIPTION
Your new MIG (GMAW) flux core (FCAW) wire
feed welder is designed for maintenance and
sheet metal fabrication. The welder consists
of a single-phase power transformer, stabiliz-
er, rectifier, and a unique built-in
control/feeder.
Now you can weld sheet metal from 24
gauge up to 3/16 inch thick with a single
pass. You can weld thicker steel with beveling
and multiple pass techniques. Table 1 lists
your MIG welder specifications.

Primary (input) volts 120 VAC
Primary (input) Amps 13
Phase Single
Frequency 60Hz
Secondary (output) volts 21
CSA rated output amps 60
Open Circuit Volts (Max.) 30 VDC
Duty Cycle Rating 40%
MIG welders equipped with gas are capable
of welding with 0.023 (0.6mm) and 0.030
(0.8mm) solid steel wire on DC reverse polari-
ty and with 0.030 (0.8mm) and 0.035 (0.9mm)
self-shielding flux-core wire on DC straight
polarity. The use of larger diameter wire
makes welding difficult and the results can-
not be guaranteed. Use of larger than .035
diameter wire is not recommended.
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
40% at the rated output. This means that you
can weld for four (4) minutes out
of 10 with the remaining six (6) minutes
required for cooling. (See Table 2).

Rating Time Time
20% 2 minutes 8 minutes
40% 4 minutes 6 minutes
60% 6 minutes 4 minutes
80% 8 minutes 2 minutes
100% 10 minutes 0 minutes
INTERNAL THERMAL PROTECTION
CAUTION
Do not constantly exceed the duty cycle or
damage to the welder can result. If you
exceed the duty cycle of the welder, an inter-
nal 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 ten minutes after the
thermal protector opens before resuming
welding. You must do this even if the thermal
protector resets itself before the ten minutes
is up or you may experience less than speci-
fied duty cycle performance.
If you find that the welder will not weld for
two minutes without stopping, reduce the
wire speed slightly and tune in the welder at
the lowest wire speed setting that still pro-
duces a smooth arc. Welding with the wire
speed set too high causes excessive current
draw and shortens the duty cycle.
