GUIDE TO DC TIG WELDING

 

 

 Before starting any welding activity ensure that you have suitable eye protection and 

 

 protective clothing. Also take the necessary steps to protect any persons within the welding  

 

 area.

Please Note:

 

 

• 

All above guide settings are approximate and will vary depending on application, prep, required 
passes and type of welding equipment used.

 

• 

The welds would need to be tested to ensure they comply to your welding specifications
