Multiplaz Welder

Anybody here familiar with it? Personnel experience? The ol' Hobart is getting cranky (don't know why. It's only 70 years old) and I've been thinking about getting a new one. The specs looks pretty impressive but before I go blowing two grand I'd like a little more info on the thing.

Neat little units!... but I think they're just too good to be true. I think the idea is great that one can throw them just about anywhere as they don't take up all that much room. You can run them on 110 or 220V with just changing out the plug which is also kind of handy. The problem with them is that they're slow and take a ton of practice to get a quality product out of it. Think of it like a plasma cutter that uses an electric current to make the material molten and pressurized air to blow that puddle through. Now take away the air so you just have a puddle. Sounds like a oxy/fuel torch, right? Pretty much all it's doing is a chemical reaction to create an extremely hot tip that just melts stuff together. Sure, you can add filler to the weld and make it a little more predictable, but it's still more of a "spray and pray" type of machine. Stuck in a ruck in the middle of an open field with a generator and no other options? You bet I'd use one! Otherwise, I'll keep my more common processes.

 

For the price of these machines, I think there are better options.

Do you have a link to Specifications on the unit you mentioned or are thinking about?

I weld; maybe my insight could be helpful; maybe not.

My local Airgas will bring in any model you want and let you test it out before you buy. It might be worth your time to check with your local distributor and see if they will do the same for you.
