[Shop-talk] cutting plate with ox/acyt torch

[john niolon]

Oxweld torch... surprised me this evening I pulled the tip and it’s a 1” tip...   so now I’m thinking I’ve got a problem with mix... haven’t used ox/act in a long time... and never on 3/4... most of my stuff is no more than 1/4 and smaller and I use a metabo grinder with a cutoff wheel 90% of the time.   I’m gonna use your suggestions and try cutting again tomorrow.   I’m using a 40/4 psi  ox/act ... might inch that up a little.. hate to admit it’s probably a technique problem.

First, clean your tip really well and have good flame shape.  Then make sure you have enough oxygen pressure and a good neutral flame when the trigger is pulled.  Make sure you have enough preheat and a slow enough rate of advance.  If that doesn't work then go up at least one size, maybe two.  3/4" is pretty stout.  What brand of torch are you using?

  usually my torch cutting is on 1/4” or less plate and my torch handles it fine

  got a piece of 3/4” steel plate I need to cut and my torch isn’t cutting clean or cutting completely through...

  I think probably I need a larger tip..  think mine is a “0” or a “1”...  or course you need to factor in the operator...

  do you think that’s my problem ???   what tip size would you recommend

  thanks
  john
