Lets start a big arguement .....

WHY ??

WHY weld negative ?

Cause ya can't get the torch hotter than the work .

Even in old vac tubes , plate ( aka "anode" cause its + )
gets hotter . They had to heat the cathode ! It was
running too cool .



S.S. , tung' negative will keep work hotter than
tung' .. works better .


Stick . 6011 . ! AC is the reason for the noise
and splatter ! Try H'F' e-welder for $200 . Its
very quiet .

Novices notice ,, Stick pos ,, is easier to start .

True , if ya overheat , the stick ,

it sends off electrons easier , but it overheats

the rod , and where are you now !

Lower penetration .


Never use an old 60hz , AC machine ,
they are difficult to weld with .


Learn on a modern hi-frequency D.C. box .



Learn on an old 60 hz box, you'll be a better welder when you move up
in power sources.

electode positive is good on thin sheet metal. ( when stick welding)

Thank You,
Randy
