Absolutely fantastic. Used for first time today and can see so not guessing where I'm welding when striking arc as with old helmet. Large veiwing area great for welding and grinding. Saves me heaps of time and should have gotten it years ago.

Robert - NSW
Great product. Price and quality of product is excellent. Easy to wear for extended periods.

John - NSW
This is my second Promax 350. I won the second helmet after registering my first Promax 350 online and being entered into the draw.I'm extremely happy with all my Weldclass helmets.
My very first Weldclass helmet is a Mach 2, purchased approx 10 - 12 years ago and is now being handed on to my grandson. The Mach 2 still works fine and has only had one new battery in all that time.
Keep the good products coming.
Regards. John Morrison.

Greg - VIC
only just purchased it. Works fabulous ! having read the instructions book, It is the easiest helmet I’ve used to change out the protective glasses & having a low battery light is a massive plus for safety . 12 mths warranty,The bag & spare lens’s is a bonus too.
Very happy, will recommend ! Cheers

Nick - QLD
Good helmet very clear crisp vision

Mitchell - QLD
The helmet is maaad, I love it, it's realy quick so I don't get any flash, I don't know how it could be better.

Jess - QLD
I love it. It is the best helmet i have ever welded in.

Mathew - NSW
My second auto welding helmet as a hobbyist.
Brilliant. Comfortable. Perhaps a bit sensitive - even in the lowest setting - but you only get 1 set of eyes.
And the rods I got with it performed as well as those at twice the price.
Will use Weldclass by choice in the future.

Mathew - SA
I am really pleased with my purchase so far. It works as well as I was expecting. I am hoping that it will last a long time without failing and I will be looking after it to help ensure that it does.
I also liked the inclusion of the welding catalogue and proper information book etc. in the box. Overall a very professionally presented package and seems to be a good quality. I feel that some of the questions for warranty registration that are required fields do not apply for home use.
Thank you.

Geoffrey - QLD
The helmet is awesome. It is much better than the ordinary helmet that I had

Jessica - NSW
I’m so happy with my new welding helmet. Iv tried cheaper ones but will never go back.

Very nice helmet, the best I have used

Purchased my Promax helmet only a month or so ago, this is my first auto helmet, very impressed and happy with it. Would purchase another no problems. Good price, Good product.

David - QLD
After using a normal old welding helmet for near on 30 years, going to an automatic one, Promax 350, has been the best thing. Clearer vision, no flicking of the mask to close the lens, clearer vision especially as age creeps up eyesight is not as good. Best thing I have ever done. Used to use welders everyday but now its pretty much home use. Would recommend Weldclass to anyone. Great product.

David - QLD
I have found my 350 helmet very functional, and have had no trouble setting it up, great design thank you very much. D Senden

Aaron - NSW
I love the affordability of your product and the quality

Gary - NSW
I did some research before buying and came to the conclusion that this unit would suit me well. All of the reviews were positive, which is a rarity these days. I checked with my local dealer and he was able to give me a very good price. I have tried the helmet yesterday and this morning and it works wonders. So far superior to my old helmet. Couldn't be better thanks. Regards, Gary

Sam Lunghitano
Nice design and very lightweight helmet , it is comfortable to wear nearly all day for welding stainless steel.The helmet works fantastic and the price is great recommended.

Annika - QLD
Already used a few times and really happy with it, very good for the price and have heard all good things about your brand

Dale - TAS
I loved my previous Promax 350 that much, I took it home to use and purchased another one for work.

Our main welder has told us it is the best auto darkening helmet he has used - must be the four sensors. He is intending to purchase one for his own home use. We manufacture, among other things, portable cabins. These have a very heavy chassis that must be fully welded - hence the need for a first class helmet that is reliable. The replaceable battery is an extremely attractive feature that is not used in many helmets. So far we have found nothing on the Weldclass 350 helmet that we would change. We will be looking at other Weldclass products to see how they can be used in our workshop.

Ken - VIC

Beau - QLD
I LOVE Weldclass helmets! After using mine at work every day of the week for the past 4 years, I could not help but purchase a Promax 350 for myself at home! I love the comfort of Weldclass helmets and for how comfortable they are to wear, and they can cop a flogging. I love seeing the changes and touches Weldclass is constantly making to improve their helmets. Top job guys, very happy with your products!

Michael - WA
Great product, love the idea of 'no more arc strikes' in the wrong place!...

Mark - SA
I recently bought a Promax 350 helmet and I am amazed how much clearer it is than my old helmet. It is also more comfortable to wear. (I just have to remember to turn it on when going to use it) old one was solar powered ;-)
