SAFETYSERVICE BASIC WELDINGWELDING TIPS SETUP

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

sufx“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

electrician before using it.

Protect the extension cords from sharp 8.

objects, excessive heat, and damp or

wet areas.
