In MIG/MAG welding, Voltage, Current and wire feed speed must be controlled for sound welding The Voltage controls the weld profile. Whereas, the Current controls the heat input, size of weld and the depth of penetration. The following table (Table – 1) gives the
Key Rules on Welding Angle, Direction, and Speed
Speed: Watch the welding puddles and ridge (where the molten metal solidifies). When wire welding (MIG or flux-core), the ridge should be approximately ⅜ inch behind the wire electrode, Hoes says. A too-slow travel speed produces a wide, convex bead with shallow penetration that …

ASSELY (cont.) Feeding the Welding Wire through to the MIG Torch (Fig. 21) Ensure the MIG torch (10) lead is straight, and the welder On/off switch (1) is turned on (Fig. 19). Feed the welding wire through to the MIG torch (10) by depressing the MIG torch
How To MIG Weld Dimes Like A TIG Welder
Pro tip: write down your welder settings inside the side panel of your machine – so you have your own reference chart, so you’ll always know how to stack dimes MIG welding. Now, remeer, your travel speed may slow down a bit or speed up – that is going to depend on how you feel using the welder and the result that you’re getting so experiment.
Adjusting a MIG is usually a go or no go process on many brands of welders with fixed voltage and wire speed adjustments. It''s either going to weld or it won''t. Some welders because of their limited adjustment will not allow the welder to weld out of range. However

How to MIG Weld - Welding Techniques For Beginners
MIG welding is often known as Gas Metal Arc Welding or wire welding (which is the colloquial term for it). It is a popular form of welding which is capable of welding (for maintenance and repair purposes) anything from 24 gauge materials to those of a half-inch thickness.
Welder Buying Guide - ToolsToday.uk
MIG welders with solid wire are more commonly used for heavy, thicker work because the continuously-fed electrode wire and ARC length are automatically controlled. MIG weld joints are a lot stronger, more ductile and have less distortion than other welding processes and are ideal for thin metal work, aluminium and alloys.
GMAW 101: Setting the correct parameters
Voltage Too Low (Figure 3)—Too little voltage results in poor arc starts, control, and penetration.It also causes excessive spatter, a convex bead profile, and poor tie-in at the toes of the weld. Travel Speed Too Fast (Figure 4)—A narrow, convex bead with inadequate tie-in at the toes of the weld, insufficient penetration, and an inconsistent weld bead are caused by traveling too fast.

The voltage settings on a standard MIG welder determine the power used during the MIG welding operation. There is always a necessary balance between voltage and wire feed speed. Especially since the wire feed speed needs to increase as the voltage also increases or else the weld puddle will not be adequately fed with filler material.
