My first real post about actual welding on the forum!
I'm having trouble with my tig welder HF start, it's an old Lincoln Norweld 131.
It's just not working when I try to start welding, I have to scratch start it every time and as I'm learning it's no good, I keep melting me tungsten......
It makes a ticking sound for about 5 seconds when I hit the pedel which I assume is the HF generator and a small component on the HF circuit board flickers a dull red while this is happening. I'm not sure if this is meant to flicker red or not. Photo below.
Once I've got an arc going ( assuming I don't bugger the tungsten ) I can actually product a reasonable weld....
Can anyone tell me how long an HF start strike should be? I'm holding the tip about 2-3 mm from the work. It's not jumping that, I'm not sure if it's me or the machine.
The flickering component it the white Siemens one in the centre.
