mig welder repco

I can only suggest you check to see if it has a cooling fan inside it. When welding in the heat it will stop it cutting out like mine does.

They are okay. As the above post stated, check for a fan. Will it take large rolls wire? will the liner & head allow 0.6 - 0.8 mm.?

For most small jobs, say mild steel up to 3.0 mm. thick, they are okay. On your boat trailer, you will be using 8.0 - 10.0 mm. plates in some sections, spring shackles, etc....

You would be advised to run say a 200 amp welder for these parts, even if you have to hire one for the boat trailer project.

I had one of these small units for YEARS. It was an Italian UNI Mig, I used to take it out on site with me. The heaviest I ever welded was 5.0 mm. plate onto 4.0 mm. SHS. Took 3 passes per fillet, and I preheated the job with oxy. I wouldn't recommend doing it again.

There are LOTS of things you can weld with this little beauty. You WON'T be able to do aluminum, you need to use at least 1.0 mm. wire, through a 1.2 tip, and damn good rollers to stop birds nesting.

Enjoy you purchase, and you will be surprised with all of the little jobs you can do.

ive got a sip gasless mig, had it for years, done some good work with it, but most of the time the wire feed is uneven etc. and yes it doesnt take long for the overheat to kick in if worked hard. And it only takes .9kg rolls of wire so it is expensive to do anything more than real light fabrication with it. Great for tacking together etc.

I'm trying to save up for a 'real mig' but not looking forward to the bottle hire fees :-(
