EXTENSION CORDS

The minimum extension cord size for this tool is 6 GAUGE for cords UPTO 25’ LONG.

CORDS LONGER THAN 25’ SHOULD NOT BE USED WITH THIS WELDER.

1.Grounded welding equipment 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.

The minimum extension cord gauge for this tool is 6 AWG for cords up to 25’ long. Cords longer than 25’ should not be used with this welder.

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.
