Welding Torch is allways NEGATIVE
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 . |
