Electrical Extension Cords
The Pro-Wedge 3XL is capable of welding very long seams. This ability may warrant the
use of electrical extension cords. It is imperative to take into account the length and wire
gauge of any extension cord used will ultimately determine the actual operating voltage of
the welder. Extension cords should be a minimum of 12 gauge and regardless of overall
length should have a minimum number of plug connections. Table 1 lists extension cord
gauge and length recommendations.

Generator Recommendations
When operating the Pro-Wedge 3XL using house power from a building circuit use the
appropriate plug and power cord configuration. When in-field generators are used they must
be rated for a minimum of 5000 watts, however a rating of 6500 watts or more is highly
recommended in order to obtain the best welder performance and temperature control. As a
rule higher wattage generators provide better performance of the welder. Keep in mind the
length and wire gauge of any extension cord being used combined with the capacity of the
generator ultimately determines the operating voltage and therefore performance of the
welder.
