Re: Will Canadian 220v 60 Htz Tig welder work in the UK?
Malcolm, over the years I have imported thousands of electrical items from the US/NA, mainly pro audio and lighting systems. The one thing you have to be wary of is the voltage.
I had many power amplifiers (of undoubted quality) imported from California rated at 220v. I had zero failures in Ireland and zero failures in Europe but almost 100% failures in the UK.
After much research, I discovered that whilst Europe is "220 - 230" volts, what many manufacturers fail to realise that depending on time of day and location in the UK the electrical supply can reach 250 volts. I believe the generating companies are mandated to supply at between 220 and 252 volts and if you read 250 volts at any time, any equipment from the NA rated at 220 with zero diversification factored in, is going to be significantly overdriven.
I suppose the qestion to the manufacturer will be what tolerances or leeway is there on the operating voltage.
The Hz should not be a problem if there is a motor drive (such as wire feed) or fan involved. It will just run slower and you should be able to adjust for that.
Personally, in this day and age, unless it has switchable frequency and is designed to operate on at least 220 > 230 minimum I would not use it in the UK as there are some extremely high currents involved with these machines.
Other people may have different experiences - this is mine.
PS I had zero failures in Dublin, because at the time, whilst the voltage generated was supposed to reach the consumer at around 240 volts, it barely reached 200 on a Saturday night!
