Get started with the Forney 210 MIG Welder! This is a breakdown of the Quick Start Guide that is included with your new machine.


1. Read User Manual Icon Read User Manual

2. Attach gas bottle and regulator hose assembly. (Tools needed: adjustable wrench)

3. Install wire spool. Insert wire through both wire liners and clamp it into wire drive. Make sure drive roll, liner and tip are correct for wire diameter.

4. Install MIG gun, turn it on, and squeeze trigger until wire comes out.

5. Tighten wire feed tension knob clockwise until wire will bend from feed tension at 2”-3”. Verify polarity is set correctly for MIG or Flux-core welding wire.

6. Adjust wire feed speed and voltage per chart on the inside of welder.

7. Turn machine on and weld. Adjust stick out, travel speed, wire feed speed and voltage as necessary to achieve a good weld. See below guide for weld examples and welding tips.

Weld Examples

Good Weld

  • Smooth bead
  • Minimal spatter
  • Good fusion


  • Too wide
  • Bead too flat
Current or WFS too high

Weld Speed Too Fast

  • Stringy and lack of fusion
Weld speed too fast

Weld Speed Too Slow

  • Melt through
Weld speed too slow

Stick Out Too Long

  • Excessive spatter
Stick out too long

Welding Tips

Optimal Stick Out

  • Stick out 1/2” +/- 1/8”
  • Short stick out = more current and more penetration
Half inch stick out


  • Affects the arc shape
  • Less voltage = tighter arc and potentially more spatter

Wire Feed Speed (WFS)

  • Higher wire feed speed = more amperage
  • Can also affect arc shape and penetration

Travel Speed

  • Affects bead width and height
  • Can also affect penetration
Travel Speed

Thin Material

  • Less voltage
  • Lower wire feed speed
  • Faster travel speed

Thick Material

  • More voltage
  • Higher wire feed speed
  • Slower travel speed
