However, improper use or abuse may lead to hazardous conditions for the user or third party or damage to the unit. Always have this manual handy at the location where the WGW 300 is being used so that it can be referred to quickly and easily.

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”...

WGW 300 from “burning out”. This can happen when the nip rollers lose traction and spin on the material, causing the WGW 300 to stop in the seam and burn a hole in the material.

Set-up Upper Contour Roller Configurations: Location: The upper contour roller (#15, Figure 2) assembly is located above the heating wedge and is fixed to the bottom of the nip arm assembly. Note: There are two types of springs, one that the roller axle mounts to and one that is used as a stiffener or “back up spring”.

• With the nip pressure lever in the up position and the wedge in the disengaged position, insert the adjustment material that you cut earlier from the template into the WGW 300 as shown in Figure 4 above: • Insert just enough in so that about 70mm of material is protruding out of the nip rollers from the point where the nip rollers pinch down on the material.

If you adjust it to tight it will rock the wedge and change the rear roller (#13) adjustment. Note 3: If you are setting up the WGW 300 to weld thin material or in very hot ambient conditions the front contour roller (#12) adjustment should be set very loose or backed off completely to reduce material dwell time (over heating material) and minimize the possibility of burn outs.

Welding Procedure Power Up Connect the WGW 300 power cord to power source making sure that the voltage is correct for the model of welder you have. Flip the main power toggle switch (#1, Figure 6) to the “on” position (up). The main power switch is located on the right of the control box, below the front handle.

Just as the welder is about to run out of the end of the seam, disengage nip rollers, slide welder out of the seam, and then disengage wedge. At this time it is a good idea to tip the WGW 300 up onto the front handle, raising the back of the unit, to prevent a hole being melted in the material from heat radiating from the wedge.
