Caution on connection of voltage detection cable
Voltage detection cable needs to be wired so that arc voltage can be fed back with accuracy. Be sure to check the following
for reducing the influence of inductance noise.
•
Wire the voltage detection cable for the base metal away from the cable of base metal. For easier handling, cut the
voltage detection cable for base metal side to a suitable length.
Connect the base-metal side voltage detection cable
to a position away from the base metal side cable.
Welding torch
Base metal side cable
Base-metal side
voltage detection cable
Make this area as small
as possible.
Do not wind surplus cable.
Do not route the cable along
the base metal side cable.
Do not tighten the detection cable together with
the base metal side cable.
