A page of the MIG guide showing four fillet weld cross sections
Real pages from the guide

Fifteen sections. Four things that go wrong.

Heat, travel speed, gun angle and gas coverage. That is the whole list, and the diagnosis table at the back is the same four sorted by symptom.

25 pages · 15 sections · 5 parts · PDF

Gas, wire, polarity and two knobs. Get these right and the arc tells you so out loud.

  • Short circuit transfer, and what the sound is telling you
  • Gas mixes compared, and why more flow is worse
  • Wire size as a heat setting, and the polarity that ruins an afternoon
  • A settings chart from 24 gauge to a quarter inch, plus a sixty second dial in routine

Four variables, and every one of them changes the weld.

  • Stick out, the hidden amperage knob
  • Work angle, travel angle and travel speed
  • Push against drag, drawn in cross section
  • Stringer, weave, circles and stitch

Reading the bead, aiming at the root, and the hardest welding most home welders ever do.

  • Four fillet cross sections: correct, too cold, too hot, no root
  • Where to aim on the butt, lap, tee, corner and edge
  • Thin sheet metal, tacking and the bare hand test
  • Plug welds, and aluminized exhaust tube

Twelve problems, most likely cause first.

  • Porosity, undercut, burn through and heavy spatter
  • Wire stubbing, burn back and erratic feeding
  • A bead that looks right and snaps anyway
  • Cutting and etching a coupon so you can see the inside

Safety, drills, and one page for the wall.

  • Arc eye, fire and fume, and welding on a vehicle
  • Five practice drills, in order
  • The two habits that separate good welders from bad
  • Before you strike, while you weld, if it looks wrong

Questions we get asked.

It is written for a hobby or home shop welder on a 110 or 220 volt machine running short circuit transfer on mild steel. The technique carries over to bigger machines, but the settings chart is aimed at small ones.

Only in passing. Aluminum on MIG needs a spool gun or a push pull torch and straight argon, and the guide says so, but the depth here is mild steel and sheet.
