4-3. Weld Output Receptacles And Selecting Cable Sizes

Y ARC WELDING can cause Electromagnetic Interference.
To reduce possible interference, keep weld cables as short as possible, close together, and down low, such as on the floor.
Locate welding operation 100 meters from any sensitive electronic equipment. Be sure this welding machine is installed
and grounded according to this manual. If interference still occurs, the user must take extra measures such as moving
the welding machine, using shielded cables, using line filters, or shielding the work area.
Y Turn off power before connecting to
weld output terminals.
Y Do not use worn, damaged, undersized,
or poorly spliced cables.
