DESCRIPTION

Your new MIG (Metal Inert Gas) wire feed
welder is designed for maintenance,
farm/industrial applications, auto body/sheet
metal fabrication and similar applications on
steel, aluminum and stainless steel. The
welder consists of a single-phase power
transformer, stabilizer, rectifier, and a unique
built-in control/feeder.
Now you can weld sheet metal from 16
gauge up to 5/16 inch thick with a single
pass. You can weld thicker steel with bevel-
ing and multiple pass techniques. Table 1
lists your MIG welder specifications.

Duty Cycle Rating
Your MIG welder is capable of welding with
0.024 (0.6mm), 0.030 (0.8mm), 0.035
(0.9mm), 0.040 (1.0mm), and 0.045 (1.2mm)
inch solid steel, bronze or aluminum wire on
dc reverse polarity and with 0.030 (0.8mm)
and 0.035 (0.9mm) self-shielding flux-core
wire on dc straight polarity.
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.
This welder has a duty cycle rating of 60% at
the rated output. This means that you can
weld for 6 minutes out of 10 with the remain-
ing 4 minutes required for cooling. (See
Table 2).

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 six
minutes without stopping, reduce the wire
speed slightly and tune in the welder 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.
