140C vs. 140HD

admin

I was prepared to buy the 140C off the internet, but for almost 150 dollar cheaper at Home Depo I can get a 140HD welder.I cant find any info on one vs the other, so could someone shed some light?I basically am using it for automotive use only, and it needs to be versatile. 110v is a must (should be able to weld anything up to 3/8'' with .035 wire.... more then good enough for automotive).Which one would be better? At first I would have to use flux core, because I cant afford a bottle and gas, jsut a side note.
Reply:If my memory serves me well,and it usually doesnt,the 140c has an aluminum drive and infinite voltage adjust.this is definitely a plus if youre into body panels .I have heard rumors that the home despots service their own welders,hasnt been confirmed but sends shudders down the spine.So in conclusion if youre planning on keeping this welder for a good long time buy the 140c professional model,youll be a happier camper in the long runCaution lurker lives here" hmmm That is serious,pass the ganja and pick up a  24 of MGD"

Reply:The 140c does have the aluminum drive and infinite voltage control, seems like a better built unit as well.
Reply:The parts diagrams and manuals for both machines are availible at lincoln's website.Check those out.There is a lot of mis-information floating around the net regarding the "HD" series welders.------------------------------Lincoln 175HDLincoln AC/DC225Smith O/A
Reply:Oh Yeah i forgot to mention this        110v is a must (should be able to weld anything up to 3/8''SAY WHAT???         Like Broccoli 1 says do not expect a 110 welder to weld 3/8 material.Just does not have the umph needed for penetration             FelonCaution lurker lives here" hmmm That is serious,pass the ganja and pick up a  24 of MGD"
Reply:We rented a 140C this past week for use on a jobsite. Using 75/25 argon/CO2 with .035 solid wire, power cranked all the way and wire speed about 1 1/2, had to move extremely slowly to get any penetration at all on 1/4 thick steel diamond plate. It did OK on 1/8 steel though.
