Hi,

I've just started to practice weld.
I have a portamig 185.
I used settings speed 2.25 roughly.
fine volts 2
course volts 2

These are my results:

Side A

Side B

14 stone on one leg.

Trying to gain confidence before taking the welder to my car.

Would be interesting to see what it would be like with the speed at mid way 5, with my Portamig it seems to sort itself perfectly for each power setting and I simply never adjust it.....however, they look good welds to me so you must be doing something right.

Use both feet and put 28 stone on it

Note third picture down was you using toast as a heat sink
or a welder to make your toast

LOL,

Yea the toast needed a quick exit through the window the day before and i was nearly late for work because i had to make more.

I got some scrap from work to practice on, wish i'd got more.

I noticed that wire seemed to exit fast at speed 3 so i turned it down to 2 and it was too slow.
I'm trying to weld but not have a high raised weld if you see what i mean.
There must be a way of achieving good penetration without the weld seam being too high.
Although the weld seems good i didn't feel in control as i needed to work fast in order to prevent blowing a hole or having the weld seen too high.

I put a tack in the middle and one at each end then welded from one end to the other.
The whole process only took about 5 seconds.

You say you had the settings both on No 2

I would have thought for that thickness 1.0mm is it? you should be using the coarse setting 1 and adjusting on the fine.

Hi steve,
Yes the setting was 2fine 2course.
I'll try it in 1fine and 5course and see what happens,
I think its about 1mm thick.

I think the wirefeed on a portamig is semi synergic so it adjusts itself with the power setting.

I think I would be trying it at 1 coarse and 2 fine first, for 1mm you should be down in the machines lower range.

1 and 5 would be about 80 to 90 amps if I am thinking straight, much too high for 1mm

I'll try that and see if it helps when i get more scraps.
