The problem is that if you run too hot with the TIG torch and end up melting the parent metal a little bit you end up with microscopic bronze inclusions in the steel. This is something a torch guy is less tempted to do since it goes against the natural welding process of the gas torch. The joints made with welding will be just as strong as the base metals and often even stronger than its base metals. One could conceivably braze weld with MIG wire using an argon tank, regulator/flowmeter set up and pressure pot but not without special equipment Flux cored wire provides its own shielding gas mix when melted by the heat from the torch flame. burn-off point so that your electrodes last longer.
