• You should make the inner cone of the flame as tall as the to be cut material, otherwise you will have to much or the little power for the cut.

  With starting the cut aim at the corner and hold the torch 90 degrees (so there is no point on the cut meterial) to the piece you want to cut. First start of at 45 degrees on the cut. Then hold the torch some 65 to 70 degrees to the cut, so the torch first goes through the side, and dont leave the buttom piece of the cut not cut deep enough ( like on 1:34). Blowthrough is a bit much, but you should try to see how much seconds it takes in order to make a good cut through the material, thickness and kind of materials takes different times.

  This is what the book "Welding Skills" (OAW cutting opertations chapter 25) says about making cuts.

• That's some soft stuff

• You sir have a very steady hand. That was such a clean cut

• muchas gracias, estoy aprendiendo a preparar la llama del cortador... y me salian muy mal... no llegaba a pasar del otro lado de la pieza, es de 5cm de espesor. En tu video ve que la llama del pico es distinta a la que yo havia preparado
  ahora voy a intentar de nuevo

• you need also to open 2e oxygen valve than the gas and than you can light it you have no black smoke it is better for the torch

• I use to do cutting just with arc welding rod.while welding.
