http://www.v8tvshow.com – 314-783-8325 – Here’s a quick tip on welding exhaust tubing with your MIG welder… do it HOT and FAST! This technique shows how to burn deep-penetrating, low-profile welds that look great on their own or can be easily dressed for polishing or coating. The secret is to use high amperage (or heat) and a series of quick tack welds, and give the work time to cool between each tack! Resist the urge to seam-weld the whole tube… you’ll have to run your welder too “cold” to prevent burn through, resulting in welds that are stacked high on the tubing, not only looking poorly, but also not penetrating as deep as you’d like.
