Tigging thin sheet steel

admin

Hi,I consider buying a cheap chinese tig-welding inverter, which has a 5 to 200 Amps range.I want to weld thin automotive steel, thicknesses will be in the gauge range 11 to 22.That machine has no pulse capability (which is said to be good for thin metal).Can I expect the welder above will tig that thin metal on it's lowest A- settings, or willpulse absolutely be needed to avoid burning holes?Yes, I am aware Lincoln, Miller, Hobart and many great makes are to be preferred, butI -sadly- can not afford these..Thank you,oldwelderman

Reply:The only thing that might be detrimental is the hot-start.  Even with a low low-end of 5A, if the hot-start is too high (or lasts too long) it is possible it could blow holes.
