I need to know about the weight of the machine

Asked by: Alex
If you do a search on google it should pop right up. However, it's just under two foot I would say.

Is gas required to weld with the Lincoln Electric Weld Pak 140 HD or will wire only weld

Asked by: Anonymous
The Lincoln 140 HD can use flux-core or the 75/25 gas and solid wire. There's a lot less splatter with the wire and gas, versus the flux core. The instructions recommend using the flux core when welding outside, in windy conditions.

Will this work properly/consistently on a normal 125v 15a outlet?

Assuming that the welder is the only appliance plugged into the outlet. I've read elsewhere that this model works best on a 20a circuit, which I don't have. In other words, am I going to have to shell out more money to wire a dedicated outlet in order to make this thing work correctly? Thank you.

Weld Pak 140 HD Wire-Feed Welder is rated 4.5 out of 5 by 108.

The performance of this welder is very good. My old welder does not compare to the quality and performance of this Lincoln. I have set this welder up with gas and the quality and control of welding with gas is much better. I have welded many brackets using 1/8" and 3/16" mild steel. The welder had no problem with the project. I am running the welder on 120v 30amp outlet and have not had a problem with the breaker. It comes with everything out of the box (minus gas if you decide to set it up for gas). The setup instructions were very clear. There are 2 different setup instructions: 1-for gas and 2 for flux-cored. Overall I am very happy with this welder.

That little welder can penetrate heat. Make multiple passes for thicker metal. I farm. I'm hard on my stuff. This welder is great in helping me fix my stuff and makes it stronger.

Rated 5 out of 5 by from This thing is awesome I had the 120 HD pack exchanged it for this haven't used the gas system yet I'm sure it will work fine because it works awesome without it! Super easy to use well worth the money if you need something that works great out of the box this will work for you

Rated 2 out of 5 by from You get what you pay for the magnum 100l gun is absolute junk. Got maybe 6 hours on this machine and i ended up returning it to home depot and plan on purchasing a miller next week. Spend the extra $$ and get a reputable machine if you plan on using this often. I will say this the customer service while returning this item was great no hassle. Needless to say, lincoln is NOT the miller killer.

Rated 3 out of 5 by from not bad. customer service isnt that great Welder works pretty good. I got it all set up and welded a little bit on some exhaust. not bad. but then after a while I noticed the regulator on the welder was leaking gas (very expensive gas). so have to turn he bottle off in between welds so I don't waste anything. Lincoln wont send me another regulator, they say I have to box it all back up and return it to home depot, or take it to one of their service centers for them to test it then have them order one. I don't have time for any of that, tired of buying things from home depot only to find they are boxed wrong, used and returned, or no good right out of the box. So at this point I really wish I would of spent a few more on a miller.

Rated 5 out of 5 by from Great 120v welder Let be clear this isn't your professional, 12 hr a day, earn your living with, welder. But for the do it yourselfer.. don't think you could beat this little powerhouse! With the optional gas hook up and ability to weld up to5/16.. this is a great machine. Lays down a nice bead.. I've got no complaints.
