Stick vs. Push-Pull MIG on Aluminum

In this video, Kevin Roy “sticks it to aluminum” and compares SMAW (stick) using 4043 electrodes with GMAW (MIG) push-pull. You’ll see a real-world setup, cleaning, and preheat, as well as welding technique, and a side-by-side results review (including a quick bend/penetration check). If you’ve ever wondered when aluminum stick is “good enough” vs. when a push-pull gun is worth it, this walkthrough is for you. Special Thanks to Ironworkers 736. Chapters: 0:00 Intro 0:27 Joints & consumables (lap + T; 4043 electrodes) 0:48 Surface prep: stainless brush, oxide layer, DCEP “cleaning” effect 1:37 Preheat + PPE reminder 1:54 Pro tips for aluminum stick (amps & rod angle) 2:44 First SMAW beads: feeding pressure, slag removal challenge 3:31 Slag & appearance notes 4:24 Switch to GMAW push-pull (pure argon, spray transfer) 5:13 Welding demos (heat management) 6:23 Soot explanation (gas flow & gun position) 6:36 Side-by-side results: bead profile, toes, ripples 7:03 Quick bend/penetration check 7:34 Push-pull penetration observations 7:48 SMAW penetration vs. porosity reality check 8:17 Where TIG fits (equipment & skill trade-offs) 8:28 Brand takeaway (4043 sticks are similar) + wrap-up Setup & materials shown Base metal: Aluminum coupons (lap & T-joint) SMAW: 4043 aluminum stick electrodes; CC DC, DCEP; ~+10–20 A over mfr. spec; 90° rod angle; steady feed/pressure GMAW (push-pull): Pure argon, spray transfer, heavier material to handle heat, push-pull to prevent wire kinks Prep: Dedicated stainless steel wire brush on aluminum only; oxy-acetylene preheat Notes: Expect tough slag removal with SMAW; push-pull gives cleaner ripples and tie-in; adjust gas flow/gun position to reduce soot Safety Always wear appropriate PPE (helmet, gloves, jacket), ensure ventilation for aluminum welding fumes, and follow your shop’s safety procedures. Key takeaways Yes, aluminum stick works with basic gear—but expect more slag and porosity and less cosmetic appeal. Push-pull MIG yields cleaner, more consistent results with better toe tie-in—at the cost of equipment and gas. Prep is everything on aluminum: remove oxides, use DCEP, and preheat when needed.
