Fumes rise straight up from the weld. If you lean over your work, you breathe in more toxic gases. Stand to the side of the weld whenever possible. Position your body so the airflow moves fumes away from your face. Use a welding helmet with a built-in respirator for extra protection. Always check that your local exhaust system works before you start.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>Tip: Stay alert to the direction of the fume. Adjust your position if you see smoke drifting toward you.<\/p>\n<\/blockquote>\n\n\n\n<h3 class=\"wp-block-heading\" >Using Correct Welding Settings<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You can reduce fume production by using the right welding settings. Set your MIG welder to the lowest amperage and voltage that still gives a strong weld. Lower heat means less zinc vaporizes from the steel. Choose a wire speed that matches your material thickness. Use solid wire with a shielding gas like argon or CO\u2082. Avoid flux-cored wire unless you need it for special jobs.<\/p>\n\n\n\n<figure class=\"wp-block-table\">\n<table class=\"has-fixed-layout\">\n\n<thead>\n<tr><th>Setting<\/th><th>Best Practice<\/th><\/tr>\n<\/thead>\n<tbody>\n<tr><td>Amperage<\/td><td>Use lowest effective level<\/td><\/tr>\n<tr><td>Voltage<\/td><td>Keep as low as possible<\/td><\/tr>\n<tr><td>Wire Speed<\/td><td>Match to material thickness<\/td><\/tr>\n<tr><td>Shielding Gas<\/td><td>Use argon or CO\u2082<\/td><\/tr>\n<\/tbody>\n\n<\/table>\n<\/figure>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>Note: Test your settings on scrap metal before you start mig welding galvanized steel.
