4.2 Connecting cable
Caution against getting the cable wet.
Avoid the connecting cable to get wet.
If there is a chance of getting the cable exposed to rain or water splay,
make sure to protect the connection with waterproof cover.
Water seeping into the machine may degrade the insulation between
ter- minals, which may cause an error or damage this product or wire
feeder.
4.2.1
About connecting cable
● The connecting cable (separately sold) is useful to expand the working space in welding operation. (See
the table on the right for model numbers.)
● Apply the connecting cable between torch output terminal (+) of the product and the torch cable of the wire
feeder.
● Depending on work conditions, it may be necessary to extend the base metal cable.
Note:
It is not possible to use the connecting cable as a junction cable.
4.2.2
Cautions about using connecting cable
● Select a model properly and use connecting cable properly, or adverse impact on welding operation, such as
voltage drop, may result. Voltage drop may be resulted from the reactance caused by the conductor resistance
or cable routing manner. The longer the cable is or smaller the cross section is, the more likely an adverse
impact occurs.
● To minimize such adverse impact, pay attention to the fol- lowing points.

Do not use leave the connecting cable slackened. Never coil the connecting cable when welding, or the
welding arc may become unstable.
