G'day all,

A few post ago the matter of inverter welders was brought up and although a little dated thought I would share what I found, ended up buying an Eutectic Ultramax for $850 as a result of thread 19274.

Great little unit I must say, it is rated to 110 amps and weighs just 3.7 Kg. spent the weekend giving it a thorough workout. The best thing was that I was able to run it off my 2Kva Honda for short bursts (the welders spec calls for 2.2Kva and the genie will produce 2.7Kva for short periods). My travelling mate has a Honda as well so we'll hook them together in parallel to give the power it needs if we have to do any emergency welding.

Thanks to Pesty for raising the question up until then didn't even know they existed

Kind regards

G'day Beatit,
I'm a mate of Pesty's (he pays me lots of money to say that on here...lolol) and I've been looking at Inverter welders too. I rang coffs harbour power tools (www.chpt.com.au) today about a Gysmi 164 which they were advertising @ $1,095-. This was $200- dearer than another site was offering them for, but the other site didn't give any details about who/where they were located (alarm bells in my scone starting ringing).
Anyway, the bloke at chpt said they don't carry the Gysmi any more but ended up selling me a Italian jobbie (sight unseen by me, so I hope I haven't made an expensive mistake!!!). It's a 130w Inverter (can't even remember the name; something starting with "E", but not Eutectic). Anyway, it was only $549- + $20- postage, so I thought for the relatively small amount of use I will get out of it and the relatively cheap price; why not have a go? If it's no good I'll sell it on ebay.
Will report on it once it arrives etc.

Now that I'm back at work, I can tell you that it's a "ESSETTI" Inverter welder that I'm awaiting delivery of.

How about posting your Business/agency details.

Or if you are not allowed to on the forum, please send them to

krobbo@optusnet.com.au.

I have just spent/wasted a zillion hours researching these 'mothers' on the yank site and trying to figure out what sort of alternator I need for my Troopy so that I can utilize a mobi-arc.

Regards

Ken Robinson

Your welcome,
our first shipment is on the way, along with a killer battery isolator, like no one has seen before ;-)

G'Day Ray,
from the company details to date

"20-30 time more efficient than anything we've seen. It's solid-state, has no moving parts, has essentially no voltage drop (ex. .035v@100a), and is ridiculously small measuring 2.5" x .75" x 3.5 including connection blades. They're also stackable and can switch un-godly amounts of current. It's break-through technology; patent docs and PCB's are in process. This was the prototype http://www.mobi-arc.com/comp.jpg We've left the world of milli-ohms and entered the world of micro-ohms."

ABSOLUTELY NO!!!!!!!

Gennies (ac variety) are NOT LIKE BATTERIES!!!!!!!!!!!!!!!!!!!!

You cannot just parallel them up as the AC voltage also need to be in phase, otherwise you will blow both gennies up by overloading them. You are dealing with lethal 240V, don't play games with it. If you want to run your welder for lengthy periods, then buy a 3.0-3.5 kW gennie and do it properly and safely.

Do not under any circumstances attempt what you are suggesting.

G'day Gary,

These Hondas come equiped with parallel cables and have a dedicated socket that permits their connection. I understand that these cables and these sockets cause the 2 inverter genies to work in sync. Honda even sell the cables and advertise that you will have 4 KVA to use.

I'm not talking some home made jerry rig to make this happen.

Kind regards

No probs then....They obviously synchronize the inverters

(I'll crawl back into my little hole then)

Had visions of what can happen when a collegue of my father tried a similar thing with two normal 240V outlets, unfortunately they were on different phases. Ever seen a welding transformer explode??? Took out half the street too....

G'day Gary,

I do appreciate the warning though, I'd hate to see half our street missing - particularly if that included me.

Kind regards
