Hi everyone. I've been MIG welding for a number of years now but being able to weld ally would be really useful so I have been trying to do as much research as possible but am finding myself more and more confused the more I read.
Basically I work at a University in Dubai and we have a TIG welder that was bought new by the uni around 5 years ago and has never been used so i took it upon myself to get it going and learn to weld ally. I got a fresh bottle of argon some filler rods and red and green tungsten. The welder is a Telwin supertig 180, I believe it must be a transformer welder because it doesn't have many settings.
At present i have the electrode connected to +. the earth connected to -. argon flowrate around 10L/min. I am trying to weld 3mm ally using a 2.4mm green tungsten, machine set to AC.
The trouble i am having is that i can't get it to strike an arc even when turned up to max (170A). If however I turn on a switch labelled HF (i guess for high frequency) then it just blows a hole in the ally instantly, even at low amperage.
Am i doing something wrong or am i just wasting my time with a transformer welder, it doesn't have foot control etc just a button on the torch.
