Hi everybody
I thinking about buying a tig welding machine
I would like to have your opinion
My needs
Other than steel and inox I would like to have the ability to weld aluminum
As I don’t have three face power supply, we are talking about a 220volt single face machine
I won’t use the machine for professional use
My budget is nearly 500 euros and if we are talking about something that worth the money I won’t have any issue to spend 100-200 Euros more.
I have no idea about the specs of these machines (other than amperes and the way the arch starts-with or without touch).
I would like to hear your opinion about what I must be careful of

My questions
#1
I have an 200 amperes inverter welder. I have seen at ebay some kits that converts these welders to tig, but I don’t know if it worth the money. What do you think?
#2
Does it worth to look for a second hand or it better to go for a new one

#3
What are the low middle and high brands in the tig welding area?
#4
After a quick search I found this from Poland
