*No arc or weak arc:
**Check that the machine is powered on and set to the correct mode.
**Inspect torch connections, cables, and work clamp for tightness and damage.
**Verify correct electrode type, size, and that it’s sharpened properly.
*Porosity in welds:
**Ensure proper shielding gas flow and check for leaks in hoses or fittings.
**Keep tungsten electrode clean and free of contamination.
**Avoid drafts that disturb the shielding gas.
*Tungsten sticking to workpiece:
**Maintain correct arc length (keep tungsten slightly above the workpiece).
**Check polarity settings and use proper tungsten type for material.
*Overheating torch or cables:
**Reduce amperage or duty cycle; allow cooling breaks.
**Inspect cables and torch for damage or poor connections.
*Inconsistent or wandering arc:
**Check gas flow rate and nozzle cleanliness.
**Ensure tungsten is properly sharpened and aligned.
**Verify correct polarity and current settings.
*Excessive spatter (rare in TIG but possible with AC on aluminum):
**Check machine settings and electrode exposure.
**Clean workpiece thoroughly before welding.
