can i hook up my miller hf251d-1 to my lincoln ranger 250 dc machine and still be able to tig aluminum, although the 250 is a strait dc machine, the hf251d-1 has a 115v ac power supply

the short answer is no. there might be a few aluminum welds you could make using DC but its few and far between .
you really need AC with high freq.
