Can anyone help me with problem with tig welder , works for short time in pregas flow then shuts off . The machine still works on stick welding , appreciate help .
Is the machine the WSM200 listed in your profile? As your in Aus there are few members over there.
First thing Id do is unplug, leave an hour to discharge then get covers off. Look for any burnt components and blow any grinding dust out.
If you get plenty of photos we may be able to identify the fault.
When it shuts off, can you describe that in more detail? Loose all power or just stop welding? Does it need to be turned off to restart?
