This unit is set up ready to go. Set Contains: 1 x Professional No-Gas MIG Welder 100Amp 230V Review: Perfect budget welder, but replace the clamp - For a cheap welder there can't be any complaints. If you require adjustability and want to do a lot of welding then going up a price bracket would be worth the investment. This has two power settings, which limits it quite a bit. I'd definitely get the model with analogue power control and the option to use gas if desired if I could go back in time. But if you're on a budget and aren't too fussy about whether your weld are a little uneven (but still strong) it will do what you need. It's easy to set up and get going. One thing I'd highly recommend is replacing the crocodile clamp with a more heavy duty one, as I initially had trouble with spotty welds. A new clamp solved that completely. I got an "ARC Welding 300A Ground Earth Clamp for ARC MMA STICK Welding Process" available on desertcart. Also be sure to get a decent flux cored wire. Review: great 100a gassless MIG - I have only had this for a short while but its been great for what I have needed, I now however need more power so I have upgraded for a Clarke 196 MIG - gass and gassless 180A - As I will now be welding thicker steel. The Mightymig100 is simple, user friendly and is well made, it will do most home jobs that you may need, brilliant for fence and gate making and the like. I used it for some automotive purposes but I found the limit of it penetration and was forced to upgrade quite quickly. ## Features - 100A Maximum performance. - Heavy-duty high output transformer and forced-air cooling to maximize duty cycle performance. - Supplied with comfort grip non-live torch, 1.8m earth cable, 0.45kg flux-cored wire and 1mm contact tip. - Suitable for no-gas operation only. - For use with flux cored wire..THREE YEAR GUARANTEE FROM A REPUTABLE UK COMPANY – Founded in 1978, Sealey is a large family run business with a vast product range.

If you require adjustability and want to do a lot of welding then going up a price bracket would be worth the investment. This has two power settings, which limits it quite a bit. I'd definitely get the model with analogue power control and the option to use gas if desired if I could go back in time. But if you're on a budget and aren't too fussy about whether your weld are a little uneven (but still strong) it will do what you need. It's easy to set up and get going.

I got an "ARC Welding 300A Ground Earth Clamp for ARC MMA STICK Welding Process" available on amazon. Also be sure to get a decent flux cored wire. ### ⭐⭐⭐⭐⭐ great 100a gassless MIG *by P***E on September 13, 2023* I have only had this for a short while but its been great for what I have needed, I now however need more power so I have upgraded for a Clarke 196 MIG - gass and gassless 180A - As I will now be welding thicker steel. The Mightymig100 is simple, user friendly and is well made, it will do most home jobs that you may need, brilliant for fence and gate making and the like. I used it for some automotive purposes but I found the limit of it penetration and was forced to upgrade quite quickly. ### ⭐⭐⭐⭐ Good machine. Poor wire *by V***O on May 13, 2015* I am a skilled welder by trade and I was sceptical about the product. I bought it just to do a bit of welding on my car. The machine is fine and is good enough for the money. However I don't rate the fluxcore wire that comes with it. I should have bought a machine that uses gas or buy some better wire. It leaves porosity throughout the weld therefore making it a weak weld. I know how to weld and have got high standards and work for oil and gas industry. Welds are inspected to xray standard. I have prepped all material to be welded but still I get porosity. It will do the job, just not very good. Tip......always keep the torch lead as straight as possible. Any kinks will cause you hassle with wire snagging inside. Don't over tighten the wire feed rollers as this too will give you hassle. If the wire was good then I would've given 5star ## Frequently Bought Together - Sealey Mightymig100 Professional No-Gas Mig Welder 100Amp 230V - Forney 37031 Nozzle Gel For Mig Welding, 16-Ounce , White - YESWELDER Large Viewing Screen 3.93"X3.66" True Color Solar Power Auto Darkening Welding Helmet, 4 Arc Sensor Wide Shade 4/5-9/9-13 for TIG MIG Arc Weld Grinding Welder Mask LYG-M800H --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/178479707-sealey-mightymig100-professional-no-gas-mig-welder-100amp-230v](https://www.desertcart.us/products/178479707-sealey-mightymig100-professional-no-gas-mig-welder-100amp-230v) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-18*
