Gas Lens For Mig Welding. It just seems to be the best all around choice. Both ANSI and AWS are more cautious recommending a shade number 11 for welding at 60-160 amps a number 12 for 160-250 amps and a number 14 for 250-500 amps.
Commonly used MIGTIG Welding Gas Cylinders. Also known as a pyrex gas saver these clear tig torch nozzles are made from borosilicate glass used for its low coefficient of thermal expansion and excellent resistant to thermal shock. Gas lens for stainless steel no doubt.
The shielding gas prevents unwanted contaminants like oxygen and nitrogen in the air from entering your welding area.
Shielding gases are used in certain welding processes and are composed of inert gas andor semi-inert gas. When I use a standard 17 style air cooled torch I almost always use a stubby gas lens. The typical gas pressure when welding with MIG tends to be around 3 to 8 psi this is very low compared to other types of welding. Pair with a CK torch for the ultimate TIG welding combination.
