Old plastic covering stainless sheet

Hello My Friend,
Have you thought about using a rosebud and removing it by heat? The heat from the rosebud should not be sufficient enough to cause any detrimental phases that would be harmful to the SS sheet. Maybe this is something you might want to consider. A spatula would probably cause more harm than heat from the torch (rosebud). Done carefully, you can probably remove the plastic without damaging the chromium oxide on the surface. If, by some chance you cause any discoloration to the surface, simply lightly wire wheel (stainless if you have it) buff off the discolored areas and the oxidation in the air should restore the chromium layer to the surface. Just a thought...

Hello Lawrence, Just to piggyback on Chuck's suggestion a bit, you might also consider using an industrial heat gun as it may be easier to control amount of heat you're applying. Regards, aevald

Thanks Chuck and Alan

PS:
About that advice you gave me on the FCAW VS. GMAW-P; You were right about the GMAW-P being superior. I moved from 0.035 to 0.045 solid wire and performance improved dramatically with both my Lincoln Powerwave and The Miller Axcess. Both power supplies responded to the larger wire by being able to do much better thin/thick fillets on gauge stuff. The 0.035 Stainless solid wire just does not like to pulse spray on thin sections.

In less time than it took me to prep the metal I was consistantly producing fillets on 12 Ga. to 1/4 inch plate, Pulsed spray transfer in the *overhead position* with about a 3/16 inch fillet size and no burn thru. It did thin to thin just as well.

The stuff runs so good it's scary. I have struggled with GMAW-P with Maxtron, Arc-Pak, Pheonix and XMT. <---Throw em all away and get Axcess or Powerwave if you need GMAW-P. (or OTC if you have a bucket of money :)

Hi Larry!
I ran into the same situation some time ago...
I used some acetone with a rag, starting at the area where there was plastic already peeling off the SS... Man - did that plastic come off with ease!!! Just be careful not to breathe too much of the acetone as you probably already know!!! In other words, I suggest adequate ventilation!!! Still, It's gotta be better than burning the layer off!!!
Ya gotta love that SS GMAW-P when it's set just right!!!

Anywho, I hope this helps.

Why diddn't I think of solvent....... sheesh.

First solvent, than if it doesn't work the heat.

The nice thing about the newest generation of GMAW-P is the simplicity of the synergic concept. The Lincoln has two knobs and two switches and the Miller has two switches and two touchpads. Both so much easier than the previous unwieldy stuff. E-Gads, I have a couple of older Miller pulse pendants that are in reality just a box of freakin knobs and the pulse never worked as advertised.
