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 3 x 1.5m

Material Set-up

The WGW 300 is designed to weld a wide range of material types and thickness from very thin PE and PP to very 
thick materials such as 1.5-2.5mm HDPE.  The WGW 300 uses a spring-loaded upper contour roller system and 
“floating” wedge design that allows the operator to weld several different thicknesses of material without resetting 
the adjustments.  However, for best results on all materials, the following set-up procedure can be used.

Important! 

Unit must be cooled down before attempting adjustments.

Please refer to the parts identification photos as instructed throughout the set up procedure.
