Clean the tip, especially the cutting hole. You should get a long straight cutting jet you can actually see when you push the cutting lever. However only slide the proper tip cleaner in a couple times as too much can take your cutting hole out of round and cause lower quality cuts and ruin your tip. Are you cutting new clean steel? Really dirty or painted steel can cause cutting problems. 3/16 in. should cut very easily. Your reg. settings are set right. With the proper size tip you should have a very narrow kerf (cut width). You can angle the torch so the flame points forward if using a bigger tip. Keep the preheat flames about 1/8 in. above the plate. You do not need to to melt the plate before it will cut. It only needs to be red hot to start the cut. With a good cut all the slag can be knocked off with a chipping hammer and not even need grinding. Hope this helps. Dave

Hi Mark,

You've got your gas pressures set at exactly what Victor recommends in their booklet "Oxy-Fuel Welding, Cutting & Heating Guide." In my experience those settings are right. Those settings apply to a size 0 cutting tip, and a travel speed of 18-26 inches per minute.

Turning up the oxygen pressure by 15 lbs puts you in the range (40-45 lbs) that Victor recommends for cutting 1-1/2" plate, four times as thick as you're cutting. The first thing I'd do is to get out your tip cleaners and clean all the orifices in the tip until you get a neutral flame that has perfect shape. If even one pre-heat orifice is less than completely clean it can deflect the stream, causing a number of potential problems including incomplete penetration and excessive slag. The orifice for the high pressure stream of oxygen is even more critical.

The other thing you can do to make the cut go better is to preheat the metal a bit. Heating it along the path of the cut until it's hot but not too hot to touch will sometimes make it start behaving itself.

All the best, Stan

when cutting with a torch and the molten metal flows in behind the flame you have the heat set to hot, lower the heat some. i set my torch at 10 lbs for gas and 20lbs for oxcy, these are working settings.

when cutting metal that thin sometimes you can tilt the torch head back from the direction you are cutting to help blow the slag out.lol

Turn up the oxygen pressure by 15 or 30 PSI.

You are either moveing to fast, holding tip at the wrong angle, or you have it so the stuff can't be blown out and away from the cut.

What I do after finally reading the directions:

Using the knobs on the torch,

Turn acy on a small amount, light torch.

Turn oxy on all the way.

Use the third knob at the top of the torch to adjust for a neutral flame.

If flame is not hot enough or too hot, adjust acy knob.

This should blow the cut metal away.
