I just purchased the plastic welder from Harbor Freight.
I decided to put the welder to the test by welding two pieces of ropalene.
Using my compressor @ 2-3psi and the welding tip hot, I heated both the side and face of two large pieces. (trying to weld them perpendicular to each other)
After heating both surfaces I pressed them together.
The heated plastic sufaces oozing out at the joint.
After letting the jointed pieces cool, I tested the bond and it failed.
The two pieces broke apart with little force.
I also tried to prep the suface w/ methy ethyl ketone on my second try,which worked a little better.
Is there a special primer or surface prep needed before welding ropalene???
Thx
