Simon K wont do me right , im out $650 , theres
no way to redesign the welder .
Its a waste of time trying to redesign it ,
The PCB would need to be redone to
screw heat sinks to PCB ,,like my other welders/plasmas .
I paid , I welded , i cant redesign nor bandaide it ..
I've never had a deal go bad so quickly
i spent weeks trying to figure redesign ...
There is NO WAY to redesign it .
Its purposeful, commercial JUNK ..
---------------------Rods---------------
Some rods have powdered metal for speed , but speed is useless
heat is too wide ,ya cant control weld penetration
Dont ever use powder in flux in the rod .
6011 stands out . On a high freq , D.C. machine it
is the
quietest , smoothest ROD ever .
It has more Range ,
1/8" AWS6011 will do 10 to 80 amps .
Try that with 6013 !
Everything today ,, is make it easier on operator
to weld with abandon ...
I dont weld with abandon , i study ,
i post here .
MIG with .6mm wire ( .023 ) is not much used today ,,
cause machines lack stitch and spot . Electronic welders
have this control inherently , its FREE .
I now have 6 H'F' TIG/electrode machines .
I will automate them to stitch sheetmetal .
Its in the cooling .
No more than 1 second stitch , 4 seconds cool,
all 6 are positioned as far apart as possible
They stitch in a chain , til they meet .
Ill stitch galvy 29 Gage to
1inch box 16 gage .
BUT FAST and automatic , on a table assembling
4 or 5 or 6 sheets at a time ..
---------------------------
There confusion on gas engines , Many think
raising compression is economical ,
its WRONG . It only speeds up combustion
to push molecules close , easier to spark-ignite .
packs mo fuel into cylnder ... wasteful ..
Mr Atkinson showed low compression wastes less
fuel . But his engine needed to be 3 times bigger ,
so you cant simply alter a Subaru flat 6 , the
pistons are way too heavy . It wont work..
Enters Yamaha/ Honda 61 cubic engine ,
racing engine , with litest pistons/rods ever made .
enough of these and you have power and
economy in an airplane ..
At 9000 rpm , it is more efficient than any motor ..
for the lite weight pistons/pins/ upper part of the rod allow
9000 rpm power ,
with less wasteful reciprocating losses .
cylinder is filled less , less hp , but expansion is
over a larger piston area and stroke
= more power , less fuel .
Another way to see this is pumping losses ..
ATKINSON varies intake valve to nix
manifold vacumn.
But for the 3 minutes on take-off , you revert back
to packing the cylinder with as much fuel as possible .
i can waste fuel for 3 minutes and lift a 1500lb plane
then pull back to 80 miles to gallon ..
Honda CBR929 Weighs about 100 lbs and has
about 100 HP , at 9000 rpm ,
But its RANGE is 8 to 100 hp ,
Its the range ! A plane with 3 engines can cruise
at 120mph , at the highest economy and
yet do 300 HP for take-off .
There is nothing close .
A Con / Lycoming has a fixed camshaft , so must generate
high pumping losses .
It cant do economy ..
a bandaide .. Lowering CR , new camshaft .. w/ little overlap
and retards only the intake to about 70 deg ABDC
and adding a turbo will improve a bit ,
Then at cruise turn off turbo ! But as you climb , apply
turbo accordingly
But engine will need 3 times more displacement to
get back the HP .
This is critical with ATKINSON , you must up the size , |

The fact that a whining cunt who cant stop complaining is unhappy with a
company means nothing to the rest of us.
You lost credibility after the third repeat.
Shut up bitch |

Wow. The nerve of them. They actually want the unit back before they'll[/quote:8a6bc0fb4d]
replace the unit or refund your money?!? How dare they. To think that they
wouldn't take your word for it and just give you your money back. Wow. It's
beyond words. You'd think that there are un-trustworth people out there or
something.
Did you read the return policy & warranty prior to making your purchase?
Guess not. Everyone I know (in real life - not from behind a PC screen) has
had great luck with their Longevity welders and plasma cutters, myself
included. One friend had a defective unit after almost 3 years and his was
replaced under warranty. He was only out $30 shipping (to send the old unit
back). My LP-40D plasma has worked great from the start and continues to do
its job.
I read in one of your other spams that you were going with the Harbor
Freight plasma as a replacement. Good luck with that. We all know everything
HF sells is of the highest quality.
If fabrication was my profession, I'd buy the brand names with the higher
duty cycles. As I only rebuild vehicles as a hobby, I'll stick with my
Hobart MIG and my Longevity plasma. |

What good is an unserviceable unit ? A flawed design ?
You seem to know otherwise .. Shill
You are an accomplice , You must be investigated and
tried and deported along with them .
------------
This is not democracy ( majority of owners of welders ) ,
this is investigation of a crime against the community ..
Its commercial theft , by a syndicate .
And the customer has lost REAL value .
But they have the money .. |

Am I understanding that they have the money for the unit, and now they want
the unit back, too?

It's a conspiracy. THEY are planning to take over the world by selling
us bad welders. When we try to build anything, the welders will fail,
causing our projects to fail, causing the dollar to lose value, causing
the economy to fail, causing us all to lose our jobs, thereby giving
heytwo way too much time to gripe about his poor choices. It's all
THEM's fault. No way is it the fault of the buyer who neglected to make
sure the horse had a leg at each corner....

Sounds like a rreal money maker , they get the $$ Now ,
They can send anything the wish , maybe 5 day old fish wrapped
in newspaper , or somethin that smells worse ..
Then they show the govt attorneys general their latest
adverts on how good their stuff is ....
And say nothing of the flaw that caused the cancellation
of model 518 ..
All the while they got the $$$$$
Longevity-inc claims they are a world class sellor
of welders .... average 500/year ...hmmmmmm
After taxes thats
$80 times 500 = $4000 .
Maybe its a store front to peddle Cocaine and Heroin ...
They will NEVER live that one down !
$4000 a year !!
You wanna buy a weld machine from such an unpopular company ?
Harbor Frieght sells 10 times that many welders and does not
claim to be exclusively a welder/genset company . |
