GROUNDING
This welder requires a 3-prong, 220 VAC, polarized, twistlock plug (not supplied). This
plug must be installed by a qualified electrician.
WARNING!
Improperly connecting the grounding wire can result in the risk of electric shock.
Check with a qualified electrician if you are in doubt as to whether the outlet is
properly grounded. Do not modify the power cord provided with the tool or
product. Never remove the grounding prong from the plug. Do not use the tool if
the power cord or plug is damaged. If damaged, have it repaired by a service
facility before use. If the plug will not fit the outlet, have a proper outlet installed by
a qualified electrician.
EXTENSION CORDS
If an extension cord is to be used with this welder, it must be rated to handle 220 VAC,
single phase at 20 amps.
1. Grounded, 220 VAC tools require a three wire extension cord.
2. 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.
3. The smaller the gauge number of the wire, the greater the capacity of the cord. For
example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
4. When using more than one extension cord to make up the total length, make sure
each cord contains at least the minimum wire size required.
5. If you are using one extension cord for more than one tool, add the nameplate
amperes and use the sum to determine the required minimum cord size.
6. If you are using an extension cord outdoors, make sure it is marked with the suffix “W-
A” (“W” in Canada) to indicate it is acceptable for outdoor use.
7. Make sure your extension cord is properly wired and in good electrical condition.
Always replace a damaged extension cord or have it repaired by a qualified
electrician before using it.
8. Protect your extension cords from sharp objects, excessive heat, and damp or wet
areas.
