Great in every respect !Review by Wilbs
Purchased the Razorweld to replace an old Cigweld unit that finally gave up after many years of service. The performance difference is significant ! The Razorweld handles Nickel and Stainless Steel rods exceptionally well and makes any welding job simple. I use the welder for many different tasks and it's light weight and easy transportability makes working in sometimes difficult access situations much easier. A fantastic unit and great service from eWelders ! (Posted on 30/07/18)
Great little machineReview by Dale Manolas
Delivery was fast to Perth. The welder is a beast given that it's about the size of a shoe box and weighs very little. It comes with a shoulder strap so you can climb a ladder with it or walk around a large project. The leads, earth clip and hand piece are all solid quality. it gives me a steady weld and hasn't been sensitive to the varying voltage around here. I bought it because i have a lot of welding to do right now. I've been punishing it for a couple of weeks and it hasn't missed a beat. Very happy with the product, price and service.

UniMig delivers againReview by Craig
This is the second UniMIg I've owned and I'll never go back to another brand. I went with a cheap Rossi machine off eBay in 2013 and I think caused me that much drama I could have cried and when it came to warranty I had issues. This Uni-MIg machine doesn't do as much as the Rossi and other cheap machines promise. But it delivers exactly what it says it will and it does it well. Lift Arc TIG is brilliant and the quality of TIG welds are great. Uni-Mig is definitely on a winner with the Jasic stuff. It's made in Asia like everything this days but there's Asian made...and there's Asian made. Big recommend! (Posted on 2/05/15)

GreatReview by Dom Bridgeland
I didn't buy this machine through eWelders but I'm on here hunting around for a three-phase MIG atm and I thought I'd give this a quick review.
I've had a couple of smaller inverters now and this is by far the best. That said, the one previous was a Rossi 3-in-one and it gave up the ghost three months after I bought. If it seems to good to be true that probably because it is. After that I decided to go with a more reputable company and am happy with the Uni-Tig 180 TIG.
I do a fair bit of stick welding with it and it's a powerful beast. I've started doing a little bit of DC Tig for some car and trailer body stuff and the quality of the welds is outstanding. The duty cycle absolutely destroys past inverters I've had and I reckon the output is a little better. That's probably because inverter technology is gradually getting better and this is a recent model.
I don't really know what else to write. There's nothing I can really fault with this machine given it's price. (Posted on 19/02/15)
So far so goodReview by Benny
Bought this about a month ago and thought I better review it. I needed it urgently and the eWelders guys got it to me overnight which was a big tick.
So far so good with the machine. It's the first TIG I've owned and it took me a little while to master it but I'm really getting to know some of the features now and happy with this machine.
TProbably the best feature of this machine is the Lift arc ignition. Took me a little while to get used to it but now that I've master it, I love it and my weld starts are really professional.
Definitely happy so far. 100% reliable and gives me professional welds on steel and stainless. (Posted on 23/01/15)
