Model 518 , welder / Plasma cutter . Transistors break legs off.

and they run 90 amps thru common relays .

Simon K swindled me . The welder cant last . Its a time bomb .



The tiny transistor leads are the "link" between two heavy

objects , the heat sink and the screwed down PCB .

In my other stuff , you cant move the heat sink without
moving the PCB . they are so rigidly screwed together ,
its impossible to stress the transistors .


But its opposite with Longevity crap . There is no way

to fix it ! You cant add additional screws from HeatSink

to PCB ! . when you unscrewed the heat sink , you'd
still have Transistor upright , "twisting in the wind"

JUNK JUNK JUNK .



Longevity sells ( extorts ) JUNK
