![]() ![]() If bubbles form, you have a leak and need to replace defective components. Use a gas leak detection fluid, available at most welding suppliers, over the hose and all fittings. (4) Check all fittings and hoses for leaks. (3) Consider using a gas lens instead of the standard collet body to provide better gas shielding. Not enough provides poor coverage of the weld. Excessive gas flow creates turbulence and swirling currents that pull in airborne contaminants and cause arc wandering. (2) Set the proper gas flow rate, which should be 15 to 20 cubic ft per hour (cfh). (1) Check the gas cylinder label to make sure you’re using the right type of gas for TIG welding (generally 100 percent argon, or an argon/helium mix for aluminum) ![]() To troubleshoot gas contamination issues: Weld contamination can occur when shielding gas is not turned on, there is too little or too much gas shielding or the gas is blown away. Throughout this discussion, please reference the application photos to the right beginning with Figure 1. (1) POOR GAS COVERAGE LEADS TO CONTAMINATION This article contains descriptions of common TIG mistakes and basic tips on how to prevent these errors from happening. Gas tungsten arc welding (GTAW), also known as TIG, is arguably the most difficult process to learn.
