Hoping for some advice. I tried some TIG welding on my inverter last year and it worked well. However, I've just set it up again in exactly the same way and the welding arc is terrible! The torch, the machine, everything is the same as it was last year. The only new element is the gas, a brand new bottle of argon.
As you can see from my image, the weld is terrible. The arc drifts around, it's noisy and the steel just melts, regardless of how high the amps are. Here's my set up -
Any help would be much appreciated as I've wasted 2 days on this.
Thanks

- DC inverter
- Earth clamp positive
- Pure Argon around 6 lpm (measured with flow meter)
- Amps around 100 but I've tried altering it and it's still erratic
Any help would be much appreciated as I've wasted 2 days on this.
