1.

Clean any oily or organic conta-

 

 

mination from the work piece.

 

2.

Tungsten electrode may be cont-

 

 

aminated. Replace or sharpen.

 

3.

Check for contaminated gas or

 

 

leaks in the gas line, torch, or

 

 

connections

3.

Check for work and electrode

 

 

cables in poor condition allowing

 

 

high frequency to “Leak Off”.

 

4.

Keep cables as short as possible.
