256 duty cycle

[geezer]

I have hit the limit but i weld aluminum cylinder heads even fried a torch lead because forgot to turn water cooler on lol . Just like Geezer i have a separate plasma since dont like switching leads

I used to be able to do things all day long,,,but 3 1/2 minutes is a long time,,,welding is like sex we think we can go to the limit,, but my girlfriend knows better..and I power out before my welder does too,
