Here’s how to use your gas torch<\/a> properly for your personal or professional projects.\n

1.\u00a0\u00a0\u00a0 Prepare a clean, well-ventilated workspace<\/h2>\nYour workspace needs to be perfectly clean so that no impurities get trapped in the molten metal. Outside, take the environment into account. When it’s windy, make sure you have a shelter so you’re not exposed to wind-blown debris.\n\nThe two parts to be welded must also be perfectly clean, free of all traces of corrosion and degreased. Use a professional paint stripper for this. Sanding with sandpaper not only cleans your parts thoroughly, but also creates microgrooves in the metal. This makes it easier to weld by capillary action, for a stronger hold.\n\nIf your parts are not spotless, you run the risk of weld defects in the form of bubbles or inclusions. If this happens, your weld will look unsightly and its strength will be called into question.\n

2.\u00a0\u00a0\u00a0 Adjusting the gas torch flame<\/h2>\nTo avoid weld defects, the gas torch flame must be precisely adjusted to provide uniform, controlled heat that is suited to the metal you are working on. You need to adjust the following parameters\n
