i have heard its possible to plasma cut with tig welder is this possible what is the most likely out come and how would i do this to get clean cut is the tungsten tip angle important for more pin point for direct burn through? or less pointed electrode -----------------------------------------------
yes some limited cutting can be done with a tig torch...here is kind of the skinny for cutting thin sheet metal .063" and under
use a 1/8" electrode with a bluntly sharpened tip
set argon flowmeter to max
set amperage to 200-250
use a #3 or 4 tig cup
recess the tungsten about 1/8" below flush with the tip of the tig cup
use a straight edge and drag the torch
This will make a wider kerf than plasma
