The time-delay fuses or circuit breaker of an individual branch circuit may trip
when welding with this product due to the amperage rating of the time-delay
fuses or circuit breaker.
The recommended time-delay fuses or circuit breaker size is 30 amperes.
Fuse/circuit breaker size is based on not more than 200 percent of the rated
input amperage of the welding power source (Based on Article 630, National
Electrical Code).
An individual branch circuit capable of carrying 30 amperes and time-delay fuses
or circuit breaker protection is recommended for this application.
Each unit incorporates an INRUSH circuit. When the MAIN CIRCUIT SWITCH is
turned on, the inrush circuit provides pre-charging for the input capacitors. A
relay in the Power Control Assembly (PCA) will turn on after the input capacitors
have charged to operating voltage (after approximately 5 seconds)
Damage to the PCA could occur if 133 VAC or higher is applied to the Primary
Power Cable.

3.4 Electromagnetic Compatibility
Extra precautions for Electromagnetic Compatibility may be required when this
Welding Power Source is used in a domestic situation.
A. Installation and Use - Users Responsibility
The user is responsible for installing and using the welding equipment according
to the manufacturer’s instructions. If electromagnetic disturbances are detected
then it shall be the responsibility of the user of the welding equipment to resolve
the situation with the technical assistance of the manufacturer. In some cases
this remedial action may be as simple as earthing the welding circuit, see NOTE
below. In other cases it could involve constructing an electromagnetic screen
