Hey fellow Kern users. I have a 400 watt HSE and have been cutting a ton of hot roll steel. We started out using regular compressed o2 tanks for our assist gas, but after blowing through those in no time, upgraded to liquid o2. Now the problem is that the kern is drawing too much o2, so fast that the liquid tank can't vaporize fast enough and freezes up on us. Any recommendations for o2 set ups??

Thanks!
