uni mig 252

[benorange]

just got my self a uni mig 252 it an older one but has 4 transformers in it so it a real good unit. only thig it didnt comewith is a book to tell me what amps it is set to. it has 2 dials 1 is course and 1 is fine. does anyone know of a book i could getthe settings copied out of.

im no expert. But i know im right in saying every welder is different. Only played with a couple of different machines but found the best way was to just experiment. Get a bit of scrap of what your welding and see what amperage gives you a nice weld

Hi, depends on who made it. I got a 30 year old Transmig 350, marked NZIG but made by CIG, I think they made Unimigs as well, but could be wrong. I sent them an email (at their sales address, the only one on the web - try www.cigweld.com.au) and 2 days later they emailed back the user and service manuals. Awesome service, worth a try if it's a CIGweld machine. cheers, Terry

No book will tell you what settings to use for a particular job.

It really gets back to experience with welding.

The problem with mig is you can have a good looking weld with no penetration so it pays just to experiment.

Generally while welding if there is a spitting sound the amps are too low. There should be a constant buzz sound, and you should see the edges have been melted into the surrounding metal.

If you are welding body panel you will generally have to stop and start on the trigger to stop blowing holes but still have good penetration.

For panel steel run 0.6 wire .Above that to around 6mm 0.8 is fine and for 10-12mm move to 1.2mm.

The other thing that can affect the amp settings is the power source. My 250 CIG welder on single phase need 6mm power feed with 35amp fuse if you want to do long welds. OK for short runs on 2.5mm wire.

Hope this helps but have a play

Others may disagree but I am writing in general terms.

i knw all that i can weld i need to know what amps the welder is going to put out cos the table that is norm on them telling you what it is is not there.

it has 2 dials 1 is course and it is graded from a to d and the other is fine and graded from 1 to 4 i think.

Depends completely on what your welding, and position. Experiment with the settings, you just said you can weld. So you should be able to tell whats working and whats not.

(op) I ran Unimig units for years, fantastic machines. Only reason I changed is our new units can be digitally preset and are inverter specs. The course setting runs all the transformers which are copper wound too and is for structural welding, it gives out a greater heat setting thats all. Sure I had a book for one but it was the workshop series so could differ. If I can find it its yours for free but hey my paperwork section is never a good area to enter into haha...
