amperage or voltage, or duty cycle, before welding.
4. This Welder, at its 10% at 55 AMPs duty cycle (low), can run continuously under
load for 1 minute out of each 10 minute period. After using continuously for one
minute, the Welder must sit unused for 9 minutes. At its 6% at 70 AMPs duty
cycle (high), the Welder can run continuously under load for 36 seconds out of
each 10 minute period. After using continuously for 36 seconds, the Welder
must rest for approximately 9-1/2 minutes.
To Operate The Welder:
1. Securely clamp the Ground Clamp (28) to the metal object that is to be welded.
(See Figure I.)
2. Set the Current Switch MIN/MAX (9B) to the desired setting (MIN = A low setting
of 55 AMPs, MAX = a high setting of 70 AMPs). NOTE: Use the MIN
setting for thinner metals and the MAX setting for thicker metals. (See Figure I.)
3. Make sure the Power Switch ON/OFF (9A) is in the "OFF" setting. Then, plug
the Power Cord Plug of the Welder into the nearest 120 volt, 30 AMP, grounded,
electrical outlet with delayed action type circuit breaker or fuses. (See Figure I.)
