Selecting The Correct Welding Current; Welding Cable Selection - Honda EW140 Owner's Manual

SELECTING THE CORRECT WELDING CURRENT
Measure the thickness of the metal you are welding and then refer to the
table below to select the proper electrode size and current setting.

IN INCHES SETTING
UPTO 3/16 l/16

ABOVE II4
15132 150-200
NOTE: Always make a sample weld on a piece of scrap material to be sure
you have chosen the correct electrode and current setting.
WELDING CABLE SELECTION
The table below shows the current carrying capacity. of various le'ngths and
gauges of standard copper welding cable. Whenever possible, refer to the
cable manufacturer's recommendations.
Always allow a considerable safety margin when selecting welding cables.
The cable's length and gauge (diameter), along with the material it is made
from, all combine to determine how much current it can safely carry.
CAUTION: An undersize welding cable will offer unacceptably high'
resistance to current flow. This high resistance.will shorten the service life
of the generator/welder, and can even make the welding cables become
hot enough to cause painful burns.
