In a TIG, you actually can see the bead before you put any filler rod in, where a MIG filler is used as the actual electrical contact. A TIG weld is more 'in' the weld, where a MIG sits on top.

Read about MIG and TIG Welding and see pictures of different types of welders, gloves, and diagrams, inside Rod & Custom Magazine.

Miller Electric Mfg. LLC is partnering with Gullco Intl. to introduce Hercules, a high-deposition welding automation system ...

For more advanced welders, the Vulcan OmniPro 220 ($800) does flux-cored and MIG welding, along with stick electrode and tungsten electrode and filler rod (TIG).

So it’s always a joy to pick up a new trick, especially one as simple as putting a hardened edge on mild steel using a drill bit as a filler rod.

TIG welding will give your cage that race car look but adds considerable time and expense to the welding process, and using the proper filler rod is critical.

MIG Welding Use a solid-core filler wire, surround it with an inert gas like argon or CO2, and your wire-feed welder becomes a MIG machine (Metal Inert Gas).

The filler rod / wire will melt and flow into the joint, filling any gaps. COOL - Allow the joint to cool naturally. Inspect the brazed joint to ensure it has a smooth, continuous bond with no gaps.
