Plastic Butt / Fusion Welder 115

Description

This Fusion Weld 115 is used slightly. It was custom built for making cheese mold hoops. It is open ended so that if a hoop is welded you can pull it off the one end. It was used for one job, and we do not have that job anymore so that is the reason we are selling it. It is designed to weld 1/16" - 1/4" plastic and has the capability to do up to 1/2" plastic but may need some experimenting to get the process protected. It was build in 2014. This machine is not automatic, but it is a operated by air cylinders and solenoids.

Owners Guide
Power Requirements:
115 volt single phase Power / 120 PSI Air
To Operate:
Begin with all air valves down, and then switch on the unit power switch (on right hand side of the control panel. Open fuse valve by PULL up (step 1). Next lift RAISE (step 2) then RAISE ALIGN (step 3). This will begin preheat. WARNING Never leave the preheat process unattended, as it will get two hot and damage the machine. Preheat should not take any longer than 5 min or damage may occur to air hoses. Once preheat has reached the preset heat you are ready to insert your pieces to fuse in the sides. Once the pieces are pressed against the yellow alignment bar PUSH CLAMP (step4) Now you are ready to PUSH HEAT (step5) this step will take trial and error to get the desired bond. You do not want to heat any longer than to get the edges completely soft. Then press PUSH FUSE (step 6) you will also need to assist the fuse manually by pushing on the plastic by hand to insure plastic is fully pushed together. Once this is together as desired, and given time to melt a little usually around 20 seconds you can turn on the AIR COOL and run the timer to about 1 min. then you will PULL CLAMP to release the hold on the plastic and cycle the PUSH PULL FUSE to reset the timer ending with the fuse open again.
The process of getting the right bond with the fuse will take trial and error. You need to get enough heat and time to get the whole edge soft but not too soft for the nicest seam. If you heat to long the seam gets ugly and rolled. If you do not heat it enough it will not fully bond. It is also good to allow margin with your job to trim edges off the finished plastic for a neater job.
Problem Solving
If heat bar is not adjusted right, one side of the plastic being fuse will heat sooner than the other, causing overheating thus making a mushroomed seam. Adjustment will need to be made to the heat bar by taking it out, and with taping and bending the mounting hole area on each end, to compensate for even heat to both edges.
Heat / Cool Guide
- (Approximate times –will vary with type of plastic and application)
1/8” HDPE = Heat - 1.05 min. / Cool – .45 min.
3/16” HDPE = Heat - .55 min. / Cool – .45 min.
¼” HDPE = Heat - .35 min. / Cool – .45 min.
