I have a plan buying TIG welder. Probably, I will purchase Lincoln precision TIG 185 or Miller ECONOTIG AC/DC or Miller SYNCROWAVE 180 SD Or SYNCROWAVE 250 DX. Maybe this is silly question. Why these machines are so heavy weight? For example, Lincoln is 117 kg, ECONOTIG is 64kg, 180 SD is 102 kg and 250 DX is185 kg. I found the only one machine, which is lightweight, is Miller DYNASTY weighted
20.5 kg. I need AC/DC TIG welder that price range is $ 1300~$1800. Any comments on those machines will be appreciated. I personally like Lincoln precision TIG 185. The main reason I care about weight is I may not able to handle such a heavy weight by myself And I have no helper. I only have a wife who probably doesn't want to help moving the machine around. In addition, I'm small guy with no macho.Thanks in advance. Yoshiyuki.
