find it necessary to increase or decrease the
amperage setting; accordingly.
CAUTION: Donot loosen and move amp selector
while welding.
The duty cycle scales: bracketing the amperage
scales are provided for :your convenience and
protection ofly0ur new welder. Duty cycle is the
performance level of the welder based on a t0
minute time span, For example welding for 6
minutes oul of 10 minutes is a 60% duty cycle. To
avoid possible overheating of the welding
transformer, which could shorten the fife of your
welder, Do Not exceed the duty cycles indicated on
the duty cycle scales.
TROUBLE SHOOTmNG
WARNING: Removal of the welder cabinet top for any reason must be done by
a qualified service technician.

Improper polarity on
D.C. range,
1. Use AC or AC-DC rods,
2. Use rod of 1/8-inch maximum diameter,
or smaller on 30-140 amp A.C. range or
use D.C. range with reverse polarity.
3, Check that cables are plugged into the
correct jacks to give polarity per the
recommended amp range table.
SERVICE TIPS
FAN MOTOR
No provision has been made for lubricating the fan
motor, as extra large oil reservoirs provide
lubrication for the life of the motor,
