3-5. Weld Output Terminals And Selecting Cable Sizes

YARC 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.
