Re: [MW:26644] PMI for ER-80s-N1

This is contractual requirements. You need to check your project specifications.

I understand your concern, LTCS does not require PMI, but you have 1% Nickel in filler metal, some cross checks are required, discuss with your client.

If you use it only for root, any way you can't do PMI on root practically.

MAG with 1.20 mm size ER 70S-6 filler wire along with Argon + CO2 ( 20 % )

is very popular and much in use now a days. SMAW process is a slow process
