The pinecil will go up to 126w if you have a capable power supply. I am going to be honest though, 16awg isn’t that large. A 45w iron could probably handle that fine if you are ok with waiting a but for your wires to get up to temp.
Sorry I thought it was 60 cause that was the newest one but looked at mine it's the haklo station 70w. Pretty sure it's 70w but could be just 70w at startup.
