Default AC or AC/DC for Welding

I'm looking for a good stick welder, preferably the Lincoln electric. I'm wondering if the AC/DC one would be better. If anyone has one they can spare, I sure would be interested.

AC-DC will allow you to do more work. If you are going to do TIG or MIG, DC only will be better.

My nephew went to welding school a couple of years ago and just recently started working in his feed. He told me that DC is losing out to AC in many welding applications. What he is work now is manly flux core structural welding.
Are you just starting to weld/ will this be your first welder?

I have both AC and AC DC. I use the DC side of the AC DC almost all the time. Buy an AC DC for stick welding.

Yes. It would be my first. I have some experience with welding. I bounced back and forth between a miller engine driven stick and a millermatic Mig.

Having DC gives more options in electrodes and controlling penetration.

I think figuring out what process would suite your needs best would be step one. A small Mig (wire feed) is very usfull for sheetmetal, tackwelding, and light fabrication. It requires a relatively clean surface. You will be limited to indoor welding unless you use fluxcore wire.

Stick welders work well on structure, farm equipment, substantial metals. They work well in the wind, and on dirty metals.

Having Ac/dc capability gives you flexability to run more rods, and do carbon arc gouging and brazing.

When it comes to arc welding, nothing welds better than DC, it is the smoothest, easiest to control, and most forgiving.

I decided to get the Lincoln AC/DC welder. It sure is a nice welder. I have already welded a cart for it. I'm perfecting my skills with it. If I can find some barrels and an oil tank, I can build this tractor I have planned out in my head.
