What are you welding? 

How THICK is it? 

Your welder has electrodes? 

Should only have a single electrode. 

Rough guide: 

¼" = .250" electrode = 250 amps 

⅛" = .125" electrode = 125 amps 

Do you see the pattern? 

Your metal better be more than 1/2" thick if you're using a 1/4" electrode and all that current. 

P.S.  I looked at your welder specs.  It's only 225 amps AC, so a 1/4" electrode is already at the maximum size for your welder wide open. 

Please explain what you plan on welding.

'I have no idea what this needs to be set on'

Then you don't need to be operating it - and please tell me you aren't welding anything important.

Answer 3

1/4" electrodes?  250 amps  1/4=250

. usually 1/8" electrodes or  125 amps 1/8=125 unless you are building the Titanic II
