MIG Welding The Expression ”Wire” With MIG welding, the electrode is wound on a reel (or drum). In this manual, an electrode of this type is referred to as wire. Synergic Welding Each combination of wire type, wire diameter and gas mix requires a unique relationship between wire feed speed and voltage (arc length) to attain a stable arc.

Weld Data Settings The following is a summary of the welding parameters that affect the welding process when using MIG welding methods. With the power source in synergic mode it is only necessary to set the wire feed speed. The voltage parameter may also be adjusted if required. When the wire feed speed is adjusted, the synergic control system automatically adjusts certain other parameters to compensate.
Hot Start The hot start function is selected when a hotter arc is necessary at weld start, so that welding defects are avoided at the beginning of a weld. Crater Fill The crater fill function makes it easier to avoid porosity and crater cracking in the weld metal when you stop welding.
