Your tool must be plugged into an appropriate outlet, properly installed and grounded in accordance
with all codes and ordinances. The plug and outlet should look like those in the following illustration.
Double Insulated Tools: Tools with Two-Prong Plugs
Tools marked Double Insulated do not require grounding. They have a special double insulation
system which satisfies OSHA requirements and complies with the applicable standards of Underwriters
Laboratories, Inc., the Canadian Standard Association, and the National Electrical Code. (See Figure
B.)
Double insulated tools may be used in either of the 120-volt outlets shown in the following illustration.
Extension Cords
⚠WARNING
• USE A PROPER EXTENSION CORD. Make sure your extension cord is in good condition. When
using an extension cord, be sure to use one heavy enough to carry the current your product will
draw. An undersized cord will cause a drop in line voltage, resulting in loss of power and cause
overheating.
• Be sure your extension cord is properly wired and in good condition. Always replace a damaged
extension cord or have it repaired by a qualified person before using it. Protect your extension cords
from sharp objects, excessive heat and damp or wet areas.
• EXTENSION CORD - We do not recommend an extension cord because of the voltage drop
produced. This drop in voltage can affect the performance of the welder. If you need to use an
extension cord, check with a qualified electrician and your local electrical codes for your specific
area.
• Grounded tools require a 3-wire extension cord. Double Insulated tools can use either a 2- or 3-
wire extension cord.
• As the distance from the supply outlet 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 tool damage.
• The smaller the wire’s gauge number, the greater the capacity of the cord. For example, a 14-gauge
cord can carry a higher current than a 16-gauge cord. Minimum extension cord wire size is shown
in the following table:
