Stage 1: Set Up the Workshop
Start on MIG
The MIG machine is the most forgiving rig in the game: continuous wire feed, built-in shielding gas and no foot pedal to manage. Learn the whole loop on MIG before you split your attention between processes.
Gear Up Before Arc Strike
Helmet, jacket, gloves and boots come before the torch. The safety training is part of progression, not flavour, and having the PPE on stops you losing time to fixes mid-job.
Read the Whole Blueprint
Check material type, thickness, dimensions and the marked inspection points before touching the controls. Material and thickness decide your settings; the inspection points decide where the score is won.
Your First Week in the Shop
Spend the first sessions repeating one joint type until your hand, not your head, is doing the work. Keep a note of the settings that produced a clean bead, because a welder who writes down 19V and 220 IPM welds the same part identically tomorrow, while one working from memory guesses.
Learn One Machine Deeply
Every rig has its own personality, and settings that worked on MIG will not transfer directly to TIG or Stick. Learn how the machine responds when you trigger and how the arc sounds at each end of its range. When you do change process, expect a fresh calibration period rather than a smooth transition.
Certification Tiers and What Each One Tests
The tiers below are a route through the blueprint list rather than a wall. Each one unlocks new machines and new materials, and every tier assumes the habits of the one below it. Pass a tier by completing its project twice: once to learn it, and once to prove you can repeat it on the same settings.
Apprentice
- Flat bar butt joints in mild steel
- Consistent travel speed on one axis

- Reads the puddle correctly
Journeyman
- Tubes, pipe and multi-piece assemblies
- Fit-up and tack placement that holds
- Second process: TIG or Stick
- No undercut or excessive spatter
Master Welder
- Multi-pass heavy plate in Flux-Core
- Aluminium and stainless TIG work
- Distortion controlled by weld sequence
- Inspection points pass without rework
Blueprint Routing: Which Project Comes Next
| Order | Blueprint | Process | What It Teaches |
|---|---|---|---|
| 1 | Flat Bar Joint (1/8" steel) | MIG | Gap spacing and a steady straight travel speed |
| 2 | Corner Bracket (1/4" steel) | MIG / TIG | Angle positioning and a sensible tack pattern |
| 3 | Ring Hoop (3/16" steel) | MIG | Curved travel and the arc that keeps up with a circle |
| 4 | Tube Frame Section (1.5" tube) | MIG | Precise fit-up across multiple welds |
| 5 | Pipe Flange (2" pipe) | TIG | Round work, crater control and pedal control |
| 6 | Gate Section (mixed) | MIG / Stick | Combining processes on thin decorative work |
| 7 | Structural Header (1/2" plate) | Flux-Core | Multi-pass sequencing on heavy plate |
| 8 | Aluminum Tank (aluminium) | TIG | Heat control on a leak-sensitive build |
| 9 | Custom Exhaust (stainless) | TIG / MIG | Flanges, bends and merge collectors |
Your First Weld, Step by Step
Prepare the Joint
Clean both faces back about an inch with a wire brush, then set the gap between the plates. Clamp or tack the pieces so they cannot move once the arc starts.
Set the Machine
For 1/8" steel start at 19-20V and 200-250 IPM with 75% argon and 25% CO2. Confirm the stick-out sits between 1/4 and 3/8 inch before you strike.
Strike and Hold the Arc
Start at the leading edge of the joint, hold the torch at 15-20 degrees from vertical and keep the arc length short. Watch for the puddle to form and flow in a smooth, rippling way.
Travel and Fill the Crater
Move at a constant speed all the way along the seam, then hold the torch in place and feed a touch more wire to fill the crater before you release the trigger.
Inspect and Reject
Let the bead cool, then run the inspection tools. A uniform bead width, clean root and no undercut means keep it. A cold-looking, spiky bead means lower the wire speed and repeat the pass.
Log and Move On
Note the settings that gave you a clean bead and reuse them on the next project of the same material. Once Flat Bar Joint is reliable, move to the Corner Bracket and keep your progress visible.
Mistakes That Stall New Players
| Mistake | Why It Costs You | Fix |
|---|---|---|
| Changing everything at once | You never learn which control fixed the weld | Change one variable per attempt |
| Welding on dirty or rusty metal | Guarantees porosity and a failed inspection | Clean the joint area before every pass |
| Skipping the fit-up check | Misaligned parts fail blueprint dimensions | Measure and clamp before striking an arc |
| Forgetting to fill the crater | Leaves a visible crack at the end of the bead | Hold position and add wire on shutoff |
| Grinding the weld without cooling it | You cannot judge the bead and you crack the root | Let it cool naturally, then inspect and clean up |
None of these mistakes are fixed by playing more in general. They are fixed by playing one job again with one change. Fix the biggest flaw, re-weld the same piece, and only move on to the next blueprint when the result looks the same twice in a row.
