cheap spool gun wiring

Try again
Ihave an older unimig 175 which seem to be the same as a unimig 190.
it has three knobs,current voltage and wire speed,a euro socket for main
mig cable,two euro sockets for dc,positive and neg, and a din socket for
spool motor I think.
I have ordered an el cheapo spool gun which does not come with plugs on
end of wiring but does come with a separate 4pin din plug,(I think) .
so how do I connect it all up.

Looks like the Unimig have a Euro connector for a MIG torch and Dinse
sockets for MMA, MIG ground lead and a spool gun power supply. My spool
gun came with a Euro plug already attached but you say yours doesn't
have one so best to fit one, they're not expensive. My spool gun was
advertised as having a Amphenol connector for the torch power but I
couldn't find any that matched but eventually identified it as a 4 pin
GX16 aviation connector so had to get a matching socket to add to my MIG
for spool gun supply. You likely need to find out what connector is used
for your Unimig spool gun motor power and if you're lucky it'll match
your torch or otherwise change one or the other to suit.

One problem I have is that it seems to have a cable for the dc with
sheilding or something ending up with a copper lug 0n it where do I put
that lug?

From looking at ones as you describe supplied without a Euro plug that
would be the power lead so it would need to be fixed to the brass core
of the plug kit.

Yes the power lead,but I am talking about what looks like shielding of
the power lead which ends with a brass lug with an 8 mm hole in it.

As you say your welder has a Euro socket for a MIG torch I do wonder why
you didn't buy a spool gun with a Euro plug to start with. With MIG
requiring different power supply characteristics to MMA/TIG and no
information about the internals of your welding power supply connecting
your spool gun to the Euro connector should get it working. What you see
as a shield is likely the main power conductor, unless you can find
something else, and I suspect will be around the shielding gas line so
that helps cool the conductor much like happens with TIG torches whether
water or air cooled.

The main power conductor looks to be a plastic covered heavy wire with
what looks like a shielding wire with a lug , I have not got it yet but
am looking at various cheap spool guns on the net,if you just get a
cheapie up on the net you can probably see the lug.
there is the heavy wire and four small wires(probably for spool motor

There is a three position switch for mma mig and tig
With the tig I just plugged it into the negative socket with pos earth
and it seems to work but I have not got a handle on tig welding yet, it
sticks all the time,I have trouble maintaining ark, I tried aluminium
with argon but not much success and I tried steel with argon, I have
welded steel with oxy acetylene on and off all my life and even
aluminium with oxy many years ago,so I thought tig would be a breeze.
I do not know the best settings for current and voltage for tig as a
beginner, or even if the voltage setting is applicable for mig

Youtube , welding tips and tricks . Jody is an excellent teacher .
Probably won't help with your spoolgun hookup , but you can for sure
learn a lot from him about TIG and MIG welding .

My spool gun with fitted Euro connector only cost £55 in the UK
delivered. Are they really that much more where you are, is it Australia?

yes but ebay is worldwide.

Should be interesting what you actually find when it arrives, I didn't
realise you were only going by the pics on the net as I've never found a
good detail shot of the end connections.

AFAIK the only way you can weld aluminium with a DC set is to use
reverse polarity to break up the oxide film but that hammers the TIG
torch as 2/3 of the heat is produced there rather than at the work piece.

Spoolgun...
I've just started Ali welding this summer - marine applications.
You should find it interesting - assuming you are coming from steel.
I'm using conventional MIG with conventional "push" feed from a
conventional-sized spool on the wirefeeder, so can't comment on
spoolgun.
100% Ar and gets into spray at low Amps - by 150A it can be sweet
(apparently it's from >=130A).
Jody at weldingtipsandtricks gave me a lot of inspiration early on.

Welder wiring with cheap spool gun wiring saves money. Installing it is simple and cheap compared to expert wiring. Make sure all wires and connections are secure.

Make sure the wire is adequate for the application. After installation, test the wiring to ensure it works
