grounded Welders
The grounding prong in the plug is 1.
connected through the green wire inside
the cord to the grounding system in
the welder. The green wire in the cord
must be the only wire connected to the
welder’s grounding system and must
never be attached to an electrically “live”
terminal.
The welder must be plugged into an 2.
appropriate outlet, properly installed and
grounded in accordance with all codes
and ordinances.
Extension cords
If an extension cord is used, it must 1.
have the following wire size: up to 30
feet, use 10 AWg size wire; 30 to 50
feet, use 8 AWg wire; Over 50 feet,
use 6 AWg wire.
As the distance from the supply outlet 2.
increases, you must use a heavier gauge
extension cord. Using extension cords
with inadequately sized wire causes a
serious drop in voltage, resulting in loss
of power and possible welder damage.
The smaller the gauge number of the 3.
wire, the greater the capacity of the cord.
For example, a 14 gauge cord can carry
a higher current than a 16 gauge cord.
When using more than one extension 4.
cord to make up the total length, make
sure each cord contains at least the
minimum wire size required.
If you are using one extension cord 5.
for more than one welder, add the
nameplate amperes and use the sum to
determine the required minimum cord
size.
If you are using an extension cord 6.
outdoors, make sure it is marked with the
suffix “W-A” (“W” in Canada) to indicate it
is acceptable for outdoor use.
Make sure the extension cord is properly 7.
wired and in good electrical condition.
Always replace a damaged extension
cord or have it repaired by a qualified
electrician before using it.
Protect the extension cords from sharp 8.
objects, excessive heat, and damp or
wet areas.
