Generator Recommendation

If using house power from a building circuit, please contact the manufacturer for advice
on plug and cord configuration. In-field generators should be rated for at least 3500
watts; however, a rating of 5000 watts or more is recommended in order to obtain the
best welder performance and temperature control. As a rule, the higher the wattage of the
generator, the better the performance of the welder. Keep in mind that the length and
wire gauge of the extension cord being used, combined with the capacity of the generator,
will ultimately determine the operating voltage reaching the welder.

Extension Cords

Extension cords should be at least 12 gauge and regardless of overall length should have
a minimum of 3 plug-end connections.
Maximum recommended extension cord length:
10 gauge, 3 wire
500 Feet

Accessories

The Pro-Wedge has been designed to weld a wide range of materials on most sub grade
types. However, for the best results on each job site, there are many different accessories
available to help make the welding process easier. For example, the independent front
travel rollers can be replaced with a wide tubular roller to help prevent sand and loose
dirt from pushing up onto the bottom sheet of material. For extreme cases of sandy sub
grades, an outrigger system and raised rear travel roller are available. Please contact
supplier for more information and pricing.
