Remedy:
Poor earth connection
Fix earth clamp directly onto the work-piece
Only on TP 2000 R.C.: r.c.unit is plugged in; welding current is limited by
the power source
Increase the welding current on the dial on the power source
Wrong ignition program has been set
Make sure the arc-force dial is set correctly
Mains undervoltage
Measure mains voltage at machine, increase the cross-sectional area of
the supply lead
Tungsten electrode has incorrect polarity
Connect up the TIG welding torch properly
Wrong shielding gas, no shielding gas
Use inert shielding gas (argon)
Wrong process has been selected
Set the arc-force dial to TIG welding (turn completely anti-clockwise)
