Welding 18 guage dirty pipe

[ryanjones2150]

Have you tried using unobtanium? Or try magic....either should work.

I have to weld thin wall duct work sometimes at work, and even after cleaning the galvanization off, it is still "dirty" so to speak. I have found using .030 cored (no shielding gas) works well. I have the ability to use either Pulse or Mig Mode and choose the latter.

I tried a few other things that did not work so well. Using a variety of shielding gasses only produced more spatter, and pulse welding in several configurations made the arc rather unsteady. I did try several pulse configurations to get the background arc to hold, but ultimately had better luck in MIG Mode.

I do that al the time buts its usually after it leaves the engine.

I have a few 1109 rods stashed away.

Those 1134 rods would do the trick too, but you have to turn H3LL upside down to find it!��

Some guys swear by Nonobtanium filler… but it is about impossible to get….

Is this for a product for sale on the open market? What company?

If you do not have time for adequate planning and preparation... you will get a garbage result.... clean and prep it first.... it will take less time in the long tun

Do you have time to tell us what type of metal ... where..??? and what process & equipment you are using..??
