I've got the stick welder they do from time to time under the Parkside brand, when I looked it it up they are made by a company and then re branded/sold off under a few different names...

The welder is rubbish, it was my first go at stick but I've done lots of Mig on cars back in my younger days, I've watched many videos so had a good idea and could get a bead down but I could only get through a 2mm stick before it would duty cycle out on me, I gave up using it after 4-5 sticks and haven't touched it since.

Dunno what the Plasma would be like
