Choosing to purchase a 3 in 1 welder is one of the most sensible things you could do when you are limited by budget and shed space. You can buy Tig welders that are on sale from Tokentools in Australia and save a substantial amount that can be put toward welding accessories. So what is the go with multifunction Tig mnachines? There are many dull and uninformed individual spreading myth and ignorance about 3 in 1 welding machines and it all has to do with their lack of understanding of how multifunction machines work.
First consider what a TIG Stick welder and plasma cutter have in common. No, it’s not the red paint, it is the type of power supply that they are. They are all classified as a constant current power supplies or CC PSU. The difference between the TIG Stick welders and Plasma cutters is the operating voltage. Tig Stick welding machine operating voltage is in the 25 volt range whereas plasma cutters are in the 100V range.
Put simply, the multifunction combo machines either have a parallel series arrangement for their step down transformer or else they have a second winding on it. A few relays and that’s it.
The next time you come across someone stating how bad these multi function combo welders are you will be able to tell them to shoosh. Don’t take our word for it, look at the warranty. Tokentools have a 5 year parts and labour warranty on all machines be it single function or multi function.
