3. Maintain an approximate 45° angle to the workpiece
as you feed into the gouge.
In other words, push the plasma arc in the direction of
the gouge you want to create. Keep a small distance
between the torch tip and the molten metal to avoid
reducing consumable life or damaging the torch.
Changing the torch angle changes the dimensions of
the gouge.
Note: A heat shield is available for added hand and torch protection (220049).
You can vary the depth of the gouge by varying the angle of the torch to the workpiece. The following tables show the
gouging profile at 45° and 60° on mild steel and stainless steel.
