Uncle Bob, thanks for the nice review! If you are a Facebook user, please check out our page and show us some of the fun projects you are working on: facebook.com/LincolnElectricRetail/
I just bought one. I love it. But I wish I didn't have to buy their specific TIG torch. I have a few different tig torch set ups at home from other machines.. cant use any of them have to buy the special one because of the gas output... Has anyone tried retrofitting a separate tig torch some how?
Hey Swampy Ryan, Glad to hear you are happy with the LE31MP. Thank you for your purchase. We wanted to make it easy to switch between welding processes. To do this, we use a universal 8-pin which makes it easy to change accessories from MIG, spool gun and TIG. That's why the TIG torch is specific to this unit. Retrofitting a different TIG torch probably wouldn't work. Wishing you a fun weekend!
Are there any TIG video's for the LE31 MP, I'm looking to TIG weld some thin aluminum tubing for a diesel intercooler on an engine swap I'm doing. I bought the LE31 and I can't find any info??? Also is there a dust cover made for it yet???
Hey Leon, The thickness range for aluminum welding with a LE31MP is 18 gauge to 3/16" using a Magnum® PRO spool gun Lincoln spool gun (K4360-1). Please reply if you have other questions. More info about the LE31MP can be found at lincolnelectricretail.com/products/multi-process-stick-mig-tig-welder/ Happy welding!
Yeah, like Sterling231 says, you require AC for TIG aluminum, this machine is DC, however, if you add the spoolgun, then you can weld aluminum. I’m not sure how well,it does, I wouldn’t think anything thick because the 140 doesn’t produce enough heat, maybe preheating you’re thicker aluminum might weld up.
Will this work for welding rock sliders to a toyota frame or the plates and hangers need to covert to straight axle. Or am I limited to basic hobby projects. I just purchased this machine and was curious. I have bigger welder but no 3 phase to run it at home.
Hey Christopher, It depends on the thickness of the metal. The LE31MP has a welding output range of 30 to 140 amps for MIG, FCAW and Spool Gun which can weld 24 gauge to 5/16". If you need more info, here is a link to the spec sheet: lincolnelectricretail.com/wp-content/uploads/2019/10/LE31MP-Multiprocess-Welder_Lincoln-Electric.pdf Hope this helps.

Yes and the most common gas used for GTAW (TIG) is pure argon. Other gas blends can be used for special TIG applications but Argon is probably what you will be needing.
Hi Adrian, it's scratch start. And if you'd like to share some of your TIG welding projects so other people can learn from you, our Facebook page is: facebook.com/LincolnElectricRetail/ Good luck with your TIG welding!
@@sarblade You are correct. If you add the foot pedal in it is a touch start. The TIG foot pedal for the LE31MP is our Model # K4361-1. Hope this helps!
@@LincolnElectricRetail Thanks for that info, I just purchased the Mig Pak 140MP, does this apply to it as well. The LE31MP is not available here. The other question that no one seemed to answer was, what is the difference between the Mig Pak and the Power Mig 140MP?
The LE31MP and the 140MP are very similar. The big difference is where they are sold. The LE31MP is sold through retailers and the 140MP through welding equipment distributors. For info on the LE31MP and where to buy, please visit: lincolnelectricretail.com/products/multi-process-stick-mig-tig-welder/

Both machines are manufactured by Lincoln. Thanks for asking and please write back with anymore questions. Good luck with your decision.
Hey Sergio, I just checked with our technical staff and they said the LE31MP has the same specs as the 140MP. So it does weld up to 5/16" multipass with InnershieldNR-211-MP .035. So the only difference is where they are sold. LE31MP is sold through retail.
Great question. It depends upon the metal you are working with and what process you plan to use. Let us know and we will get an answer to you. You can also find more info and download the product sheet here: lincolnelectricretail.com/products/multi-process-stick-mig-tig-welder/
Hey JB, Thanks for asking. This is a DC-only machine. If you would like more info about the LE31MP: lincolnelectricretail.com/products/multi-process-stick-mig-tig-welder/ Hope this helps!
Hey Ty Jack, Thanks for asking. Here are the duty cycles for the LE31MP Rated Output Current/Voltage/Duty Cycle 95 A / 18.75 V @ 60% MIG 115 A / 14.6 V @ 60% TIG 80 A / 23.2 V @ 60% Stick More info about the LE31MP can be found at: lincolnelectricretail.com/products/multi-process-stick-mig-tig-welder/ Happy welding!
It's fantastic for home/farm/hobby use. Smooth welding, and tips are cheap. The TIG torch option was a bit spendy. I have no need for a DC spool gun.

90 amps is enough for 1/8 6011 i run 90 amps for 6011 all the time on a buzz box

You need a AC current machine the LE31 mp from what I know of the LE31 does not have it

This is hot
Literally
Do I need gas to. Run tig
Yes and the most common gas used for GTAW (TIG) is pure argon. Other gas blends can be used for special TIG applications but Argon is probably what you will be needing.
This is a TIG question...to start the arc, would I have to scratch start or lift arc?
Hi Adrian, it's scratch start. And if you'd like to share some of your TIG welding projects so other people can learn from you, our Facebook page is:

I understand a scratch start, but if you add the pedal, isn’t it a touch start then

Is it just that this is the newer model??
