It is very rare that the lowest quality product is the best and in this instance the cheapest will be...

Anything that you could do with acetylene can be done with LPG except actual welding, apparently doesn't produce enough heat,

It is a binzel style mb 25 ,which will work better than the 24
It will take the same teflon liner as all the other binzel style guns and the same contact tips (m6 thread only)
that should work...

You can definitely use this machine for aluminium and you will get good results ,
Just change the liner to a teflon type and the drive roll to a u groove. both are easily available from most welding...

The panel socket and connector are universal 25mm all welding shops should have them on the shelf expect to pay about $25.00 for both

Have a look at the contactor, check you have the same voltage across both sides when it is energised ,It is common for the contacts to burn away over time

Hi,
The polarity needs to be changed and its easy with this machine, just the connections at the front
the wire guide can remain the same and knurled rollers if you need them should not be a...

"Vernon seems to know what he is talking about"

Vey few circuits are protected by a 15 amp fuse
If your power supply is wired correctly, it will be with 4mm cable (2.5 at worst)
and protected by at least a 25 or 32 amp breaker backed up by a 63...

I've run that machine from a 15amp outlet with no problems

Its probably easier to make one yourself
Just get the the fitting from any welding shop and use a small piece of 5mm hose the 4mm small hose will clamp nicely into it

I agree however I don't think this machine has an external socket to make the change

There are harris electrodes which will do a reasonable job (with a bit of practice)

This is a great thread
All the way from cheep chinese welders to wiring light bulbs in in series to make them last for ever (and stuff in between)
Well done
Take a bow guys :D

If you are not able to get a weld with those electrodes it might be worth getting the shop to have a look at it
or it could just be your settings generally with small inverter welders they either.....

This is the first time I have heard anything bad about this machine
I know lots of welders who use them not only diy, It handles industrial use better than it should for a $300.00 machine

Of the 3 machines listed the only one not made in china is the lincoln
Thats made in America's China "Mexico"
That said it is probably the better of them it is however the heaviest and it does not...

They are a good machine
However spare parts for older machines are very hard to find
and very expensive if you can get them
I would say avoid it unless its very cheep

It will fit the bottle
But its a very very old regulator
I would buy a new one I wouldn't like to have my face to close to that
when full bottle pressure is released into it

My advise for what its worth
Do not specify a brand of electrode or wire but rather a grade or Australian or international standard
I have come across many jobs which specify which company you...

Can I change my mind on the unimig 190 inverter
With a spool gun included for around $1100.00 it looks like good value

I reckon the unimig is the weakest one there (very heavy and draws quite a bit of current)
I'm haven't seen the mig 200 so for me its an unknown
The cig looks good and is light and as a mig its...

The only regulator I will use is a Harris
They are made in America or Europe for the extra few dollars you get a quality reg that will out last the cheep ones by years

I agree
Its the gas change to an argon mix

I would make sure I was using a Harris torch and tip
then you only need 1.5 from the lpg cylinder
Also the tip is designed to work with lpg
Unlike the normal tapered tip you are less likely to...

My opinion you can't beat the lincoln 180c with the optional spool gun
expect to pay about $1350-1450.00 for both the spool gun and the machine

The 170 is just a stick/scratch tig welder
The 170i is a mig /tig/stick although not a very good stick it is a very good mig welder
I would go for the 170i and get a trolly for the gas bottle
