Welders

Can someone explain to me what duty cycle means. So is the higher the percent better or worse?

Duty cycle is the percentage uf power usage during a 10 minute cycle...
Most 110 welders are rated at 30%   witch is a kick out point   That means weld for 3 minutes ...drink beer for 7 minutes weld for 3 mins and DRINK BEER FOR 7 MINUTES... Bigger 220 welders are often 60% to 70%...wich means less drinking time between welds

That's partially correct.  The duty cycle is for a specific output.  Turn the welder down a bit and get a better duty cycle.  And that is actual arc time by the way.  Think of it like rolling a tire up a hill.  When you are throwing sparks you are pushing the tire.  When you stop, you let go of the tire and it starts rolling back down the hill.  Point is,  if you are stopping and starting frequently, it takes a lot to hit the duty cycle of a quality machine or get the tire all the way to the top of the hill.

I run a 220 welder and a 120 welder. Was wondering if I could buy a big tank and run both off the same tank? Is this possible or not? Have a little tank on the 120. Little one keeps running out.

Keep a tank on each and get a spare so when you run both tanks empty on a sunday you can still keep going.

Yours run out on Sundays too?  Must be O's fault.  rofl

Unless the 2 welders are on same welding cart or one is only rarely used swapping the cylinder kcab and forth kinda a pain.

Not that I know of. Some of the pros here may know differently.

Never a once. I run at about 40% machine capacity average and that ,of course ,greatly increases duty cycle as you know.
