Decided to use the lockdown period to try and learn some TIG, never having done it before. Got some kit ordered and got it set up. Found the tutorial on here very helpful and useful.
I'm using a thermal arc 175 inverter with lift tig. One question, how do you stop the arc on a lift tig machine? I wanted to leave the torch over the end of the weld for a few seconds to mimic the post-flow you get on the posher machines but the only way I can stop the arc is by lifting the torch right away from the weld.
Using a number 7 ceramic with a gas lens and pure argon at abut 6LPM, 1.6mm red tungsten.
These are without filler rods as I'm still waiting for those!
I find sliding my hand along to keep in the correct position quite difficult but I guess that will come with a bit of practice.
Amps are above the pics and are as displayed on the dial on my machine. I know from arc welding with the machine that indicated amps are a little higher than the are probably are in reality hence starting high.
first one 50 amps
Second one, 50 amps
Decided to listen to the what I'd read in the guide and run some flat straight beads.
Third one, turned it down a bit to 40 amps
Tried a joint still at 40 amps
Any tips/advice appreciated. I'll give it a go with some filler rod when that arrives.
