Ceri and The Collaboratory Crew
In class, we are using a 110v (standard household plug) Lincoln, Home Depot Model.
A 110v will weld structurally up to 3/4".
I recommend, Lincoln and Miller, as they've innovated Welding for 100 years. That's what we use and have even purchased a used Lincoln off FB market place. I know when I buy Lincoln or Miller my local Welding Supply store will work on them, if anything goes wrong.
I use either Lincol wire, size 0.30 for my 110v and 0.35 for my 220v machines. We buy our wire at the welding supply store or lincoln wire at home depot.
I would check on line, one of my favorite stores is https://www.weldingoutfitter.com or your Welding supply store or Home Depot.

All Steel Suppliers have scrap piles and remenant options. Always seek that out.
Here it is, the Jeggs Cut 40, currently only $233 on Amazon. Great little workhorse. The spec says it cuts up to 1/4". I generally use it for 20 - 18 gauge sheet steel and it cuts like butter and for that price, every household should have one! https://www.amazon.com/JEGS-81545-Plasma-Cutter-220VAC/dp/B078WHZ564/ref=sxts_sxwds-bia-wc-p13n1_0?cv_ct_cx=plasma+cutter+jegs&dchild=1&gclid=CjwKCAiA8Jf-BRB-EiwAWDtEGk1gtB3I5bacjud8h4aLntkczd_YMDoR6DrEdDphCq55c7L-map09hoCjiIQAvD_BwE&hvadid=323516580907&hvdev=c&hvlocphy=9030031&hvnetw=g&hvqmt=b&hvrand=11935546420188893773&hvtargid=kwd-424652246076&hydadcr=11957_9729769&keywords=plasma+cutter+jegs&pd_rd_i=B078WHZ564&pd_rd_r=f59c910d-24de-490c-b474-d6d73bb83539&pd_rd_w=JQQ7X&pd_rd_wg=AmvSl&pf_rd_p=1835a2a9-7ed8-48dc-ad07-fcd7527bd2bc&pf_rd_r=S9DPHZCNFHR5NDC3KBRP&psc=1&qid=1606885792&sr=1-1-80ba0e26-a1cd-4e7b-87a0-a2ffae3a273c&tag=googhydr-20
If you want to go a little more high end, I would highly recommend "Hypertherm" as the rolls Royce of Plasma Cutting.
