Happy to be proved wrong though. Our goal with this story is to let you in on a little secret: When the arc forms, the electrode melts and becomes part of the weld.
If the weld puddle is disrupted by ambient airflow, flow should be increased to 20 cfh. Budget Handling Upgrades for Vanishing Paint 25: Cookies Policy. Moving the torch too quickly along the piece causes you to lose puddle control.🔥 How to TIG Weld Aluminum for Beginners - TIG Time
