NOTE!
Welding arc outs may be experienced if an extension cord is used when STICK welding when operating the
Power Source on 95 VAC due to the lack of DC voltage at the STICK electrode.
Input Power
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 Main PCB1 will turn on after the input capacitors have charged to operating voltage (after approximately
5 seconds)
NOTE!
Damage to the
Main PCB1
could occur if 140V AC or higher is applied to the Primary Power Cord.

3.07 Electromagnetic Compatibility
WARNING
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 elec-
tromagnetic 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 enclosing the
Welding Power Source and the work, complete with associated input filters. In all cases, electromagnetic disturbances shall
be reduced to the point where they are no longer troublesome.
