Well I actually bought the Parkside gasless MIG welder a month ago and from my practice pieces it seems to work ok, as has been said the operators skill is important and there are plenty of videos around to assist your learning.

Never thought about interference from it, why would I as there are pages of bumf on the regulations it complies with? If I ever use it in anger I will report back.

The manual does say ‘not for commercial use’ and that the welder is a class A device that can be used in all areas except living areas and areas which are directly connected to a low voltage supply that (also) supplies residential buildings. It also does mention in detail about radiated interference. Also it is intended for use in an ‘industrial environment’. so confusing at best?

Exactly, thse welders and plasma cutters are not legally fit for either hobby or professional use. The conducted emissions and harmonics are too high to allow use on a non-industrial mains supply. Their durability and duty cycles are such that the supplier prohibits their use professionally for liability reasons. The only way they could legally be used is if you are doing hobbyist work on a site that has an industrial supply with no connection to domestic premises.
This does not mean they don’t work. Equally just because the user is not aware of ill effects does not mean they are not there.

One effect of harmonic currents is overheating of transformers in the mains distribution system. No I’m not suggesting the Heathrow black-out was caused by a Lidi welder. But the increasing use of electronic power supplies that generate harmonics IS putting additional stress on the electrical infrastructure that was designed and built before widespread use of these devices was envisioned.
