tig with ranger 8

admin

Hi,what is required to tig with a ranger 8?is it possible to tig in the ac position, for welding alu?Since I don't have hf, would it only be harder to start welding, or also put more limitations?Is the ranger 8 ready to accept a foot pedal as is, or is another module required?My main use would be to weld aluminium.Thanks
Reply:Do a search, this exact topic has come up before.You cannot AC tig with out a Hi Freq on a sine wave machine.Ranger 8 has no remote capabilities.It can be done, but there sure are better machines and ways to do it.David.Real world weldin.  When I grow up I want to be a tig weldor.
