See the Jasic on the front???

Its exactly the same welder as the one i just payed $488 from out of china....Mine is Jasic brand....And Orange, Everything else looks identical.

Mine shat itself after about an hour, but has a two year warranty and they sent me new stuff, have yet to try it out with the new circuitry fitted.

Cheers.

Well considering it took a week of discussion and stupid tests, then two weeks for the parts to get here, and now i have to get someone to fit them....Your option isnt so bad Heath.

You just take it back and say "Daisy Chains #@$^%&" and get it fixed.

Cheers.

Heath,

The data sheet on the machine states HF start.

You said is was scratch start, have you used it yet?

HF is good but not needed for geneal use although bloody handy.

You just misread what I said

and it also has a proper start feature where a simple DC inverter with a tig torch would just use scratch start.

Yeah I used it at work the other day and it was really bloody good, I was very impressed. Haven't used it at home yet but I should have a gas bottle in about half an hour!

My tig just blew up tonight!

Its called a "mega tools ac/dc200" i noticed the hf start was fading for a while and almost had to almost scractch start it, then swapped the electrode over to do some ally work and couldnt get it to arc it just buzzed for a while, then BANG!

Its got the same looking front as what we have been seeing four knobs on top five on bottom, squiggly line between and a lcd display....

Should i attempt to get it fixed? Are all these welders the same? Or should i buy a more reputable one? With maybe better internals?

Im considering just getting a reasonable quality HF DC only and save the ally for the workshop...

I dont have a warranty, i payed $400 second hand for it.

Hey guys, sorry to bring up an old thread but I just wanted to see how some of you guys have got on with your uni migs/ jasic tigs? I have had mine for 6 months or so and it has done a fair bit of work but nothing that should have worried it and it has always been looked after well. But today after welding up some stainless there was a big bang and smoke came pouring out of the vents and obviously that's the end of that welder. Has anyone else had a problem like this with theirs being unreliable?

 

I am thinking i'll get it fixed under warranty, sell it and then buy a new Miller dynasty 200dx or Lincoln v205

 

cheers

well I've probably done alright to have mine go for as long as it has haha. I guess it's what happens when you buy the cheaper stuff.

I am still happy with my weldsmart machine i purchased on page 1. 

 

I have been through just over 2 bottles of gas since (appprox 20 hours seat time) and it is still going strong.

I think I may upgrade after getting this unimig fixed. I don't want to be worried everytime I use it that it will break down, especially if I start doing more work for other people.

 

cheers

I used to sell all of these machines and unimig were constantly coming back for repair, my own machine (boilermaker. 19 yrs) cig weld transtig 180 ac/dc that I picked up as a trade in for cheap. If I was buying new I'd get a Kemppi mastertig, I wouldn't bother with anything else but that's just me.

I ended up keeping the unimig after it was repaired but I still got a miller which is excellent. I haven't heard a bad word about kemppii welders before, they seem to be top quality.

 

cheers

I know this is detracting a bit but is everyone using gas, can you get away without it?

Now known as GTAW,

 

or Gas Tungsten Arc Welding.

 

You cannot get away without using gas...

Obviously a shielding gas to prevent oxidisation. As i've never used one thought there may be some sort of flux core filler rod you could use to get around it... What gas is it? Argon, CO2?

Usually argon.

 

However, the reason that its now called GTAW is that there are now some fancy pants kinds of tungsten arc welding where the gas is not inert, it is an active part of the welding process.

 

Google it for more info.

hi guys,i will be wiring the shed out down the track to suit a good mig welder and willing to pay 1200 for one or a fraction higher.something that can weld panels and up to 7-8mm. the house is only 10amps so that means i will have to put fuse box in shed and have a seperate line.most good welders are 15-25amps will this affect normal power tools running and will i have to have different power points for  tools etc

 

 

cheers in advance

 

Maz
