hello everyone , i'm a new guy , just registered
ronald here from the netherlands
i blew up the wirefeed my mig welder (toy motor and plastic gears started breaking teeth at the first tack)
since the welder was basicly new i bought a new better wipermotor style wirefeed and eurostyle weldinggun and upgraded the wirefeed pcb with some stronger stuff to handle the bigger motor added a gas solenoid while i was at it and then miswired sumtin turning the transformer intoo a smokegenerator after plugging it in for the first time........ ohw sh.t
since the wirefeed part and the gassolenoid is still ok i was planning sumtin simulair as HughF is doing right now building a suitcase style remote wirefeed to set up as a topbox on my welders cart
but do all the innitial weldpower regulation on the powersuply itself
i have only one question : i want to use a Giant TIG200P 200A AC/DC TIG/MMA welder in the dc setting as the powersuply
does anyone know how to set the dails for mig i will be using 0.6 and 0.8 wire
btw the new mig welder parts and stuff i bough was from a guy in england that has pretty good afterservice too :

Sorry to give you bad news but what you have is a Constant Current power source (CC) and MIG welding requires a Constant Voltage power source (CV).
Stick and TIG welders are CC and MIG sets are CV.

You'll be able to run in spray transfer off that power supply, but no chance running in short circuit without using a voltage sensing feed system. Tec-arc sell them, but I'm not sure if they will sell you a pcb that you can use to build a feeder from. I have a cv power supply, so I don't need the voltage sensing features of the feeder.

In the words of a certain mr tong... We continue...
Decided to use the toroid+rectifier option... Will mount the relays and Pwm board inside the lid.
Input/output connector is wired, gas solenoid is wired, power switch is wired, led is mounted, spool/internal changeover switch is mounted.
Waiting on the relay board and some more black/red wire from the office and I can start working inside the lid.

this is something i need to do sometime, or butcher something i already have but it ill have to get in the queue for now.
so i havnt went mad researching things until the time comes but im constantly curious all the same.
cv supply i take it, what voltage are you running the wire feed unit on?,
how many cables go back to the welder in the multi plug, and what do/can they control if you dont mind me asking.
the mechanical stuff is no bother to me but the electrical stuff is always a learning curve, im not an expert in wiring but with some research i do always manage to get things wired but its a whole science on its own.

Cv supply, yes. There are 2 'control' cables going back to the machine although you could get away with one. One cable is a 3 core for the remote, so you can adjust the voltage from the feeder. This one is optional obviously.
The main one is a 4 core and carries 120v (American, 60hz machine) to power the feeder along with the control wires for the contactor inside the machine. You touch the wire to the work, the machine revs up, pull the trigger and the contactor in the welder closes, and the feeder starts to feed wire and flow gas.
It's pretty simple stuff and is documented in the handbook for the weldanpower250.

Yes, I was thinking that Jim, you're correct. But I'm pretty confident the bullet proof power supply (transformer/rectifier) should cope with the power coming up when I hit the wire to the job. Got to fix the idle circuit first though, it's still not right...
Another option is a 250w 110v inverter buried inside the weldanpower.

I disabled the auto throttle on my Honda as I was worried about either damaging the welder or damaging the generator when such a surge came when the wire hit the job and the amperage cranked up

Oh, and the spool holder is mounted in the back now...
A 100u electrolytic across the trigger input for the gas solenoid gives 4 ish seconds of post flow
you can see it soldered onto the back of the relay board in the above picture. The wire relay is setup so it brakes the motor by shorting the motor wires together as soon as it is de-energised, couple this with a 4.7u cap across the control relay, should see me get a rudimentary burn back control set up. I need to have a hunt for a 4.7u cap at work...

You seem to know your stuff.
I did a wire feeder, I have two wire feeder units that have a beefy drive motor and 4 roller feeds, nice bits of kit. I rigged one up to my cheap n nasty Sealey 150a to provide the power while having the benefit of a decent feed mechanism, eurotorch, 15kg reels etc. I even wondered about getting two identical welders powered together to give a 300a MIG which I'd really like, but didn't get that far as without the required electrical knowledge it was just rubbish and so it got abandoned.
Turns out i'm even worse than Sealey at building welders!

I reckon thats a yes Hugh. My Miller 8vs is near on 2000quid new so people surely would be interested in a cheaper alternative?

what if hugh wants 1900 for his tho.......
I'm sure he won't. You'd sell them cheaper to get the customers or there'd be no real point - would £1850 be suitable?
