Product Overview

The Smarter Tools MIG-135 Welding Kit is the perfect choice to do projects and repairs around the home, farm and auto body shop. This MIG welder will produce a cleaner bead with less splatter than a regular flux core wire welder. The welder runs off of a standard 120-Volt household outlet and produces an output range of 20-135 amps. It uses standard flux-core wire (E71-GS) or steel wire 0.6 mm, 0.8 mm in diameter and has 4 heat settings to easily adjust the output according to the thickness of metal you are welding. The welder can easily switch between gas-less flux-cored welding for deep penetration on thick steel or gas-shielded MIG welding on thin Gauge steel, stainless steel or aluminum. Package includes: MIG 135 welding power source, MIG torch with 7ft. (2.1m) lead, ground clamp with10ft. (3m) lead, 2 extra contact tips, a 1lb spool of flux wire, a 2lb spool of MIG wire, 0.6 mm and 0.8 mm (0.025 in. and 0.031 in.) drive roll, 0.9 mm and 1.0 mm (0.035 - 0.040 in.) drive roll, an and adjustable gas regulator with a hose, ST-1S Auto-darkening welding helmet, gloves, user’s manual and welding cart.

Rated 3.7 out of 5 by 18 reviewers.
Rated 5.0 out of 5.0 by great starter kit! This is a great buy for the beginning welder. It is complete to start welding right out of the box. I had a lifetime welder help me set it up, and he was really impressed with this unit. $80 cheaper than Amazon! January 19, 2016
Rated 4.0 out of 5.0 by Great product Is a great product easy to us and the options are very good for the price December 22, 2015
Rated 2.0 out of 5.0 by You get what you pay for At first, I thought this combo welder was a great deal...but I realized there was a reason it was so cheap; Because It is Cheap. It has worked, but not effortlessly. Conditions have to be ideal with the thing to arc. I have to use needle nose pliers to change the contact tip. The Flux core wire that comes with it is only suitable for sheet metal (I guess, since it didn't work on steel plate). The gloves are super thin and don't provide much insulation from hot objects. The cart barely goes together because the assembly screws are so short. The only benefit, other than the cost, is that you can integrate gas into the process...but I haven't tried that yet so who knows? May 30, 2013
Rated 4.0 out of 5.0 by great for beginner welder I've never really done much welding before but with this set up it is pretty easy to learn. I really like it l, easy to use and good for the money everything you need is there except for the gas but they give you the hose regualter and the wire if you wanna mig weld. I gave it 4 stars instead of 5 because like some of the other comments say you do have to mess with the wire feed to adjust quit a bit and it needed more instructions to calibrate the wire feed at least for me I needed it but overall it seems like to be a good bang for your buck September 12, 2014
Rated 4.0 out of 5.0 by Lot of welder and accessories for the money..Great starter kit Overall a nice package. Out of the box it didn't feed wire, had to take the panels off and finally figured out that the fuse holder wasn't properly holding one end of the fuse. Once cinched up it works great. Super auto-darkening helmut provided. Side door to wire feed area doesn't close well and could be better designed. I bought a CO2/Argon tank and all is working well. I had to put in a 30 amp circuit into the garage for the welder but allowed me to add some other outlets as well. Satisfied with this purchase May 29, 2012
Rated 1.0 out of 5.0 by Save your money and by a Lincoln The quality of the product is poor. I have had to buy a better ground clamp and the gauge and hose leak (yes i used Teflon tape). It will take two weeks for the parts come in. The only piece I can say anything good about is the cart. Unfortunately I am still unable to test the welder but it looks like I will be dumping more money into it. The parts are very cheaply made and I could have done better going to Harbor Freight. It does not say much for Home Depot to sell products of this poor quality. July 30, 2012
Rated 5.0 out of 5.0 by My smart tools mig 135a welder Before I purchased my machine, I had never really welded anything. I have a seen it done many times but at that point I was rather clueless. Within a few minutes I had my welder out of the box and ready for use. I really like the convenience of having everything mounted on the included cart. And with the flux core wire included I was able to use my machine day one. I put on the included self tinting visor and once I had rounded up some metal I started welding. The simplistic design made my job easy. Just set your power level and wire speed and start welding. It was that easy. I haven't had a chance to test the solid core welding yet but I look forward to mounting an argon bottle and getting started. The only item that was included and replaced was the chipping hammer/ wire brush due to poor quality but it was an inexpensive endeavor. Outside of that I have been pleased with everything included in my kit and would recommend it for anyone of any experience level. November 9, 2013
Rated 1.0 out of 5.0 by Takes time to calibrate to make the weld need. Have to adjust wire feed to much to calibrate weld start May 6, 2014
