The wes 50 is junk.the connector is really crappy and not compatible with any other weller station and the iron itself is also flimzy. The handle is coated in a foam rubber and the hot end is pressed in the handle (not screwed) so after a while the plastic handle settles a bit and the hot end becomes loose.
I just bougt wmrt and wmrp on amzon for 40$ open box. Those are like 700$....
