The Easiest Way to Stick Weld Square Tubing

Learn the most effective techniques for stick welding thin-wall square tubing without creating burn-through holes in this comprehensive 14-minute tutorial. Watch expert welder Austin demonstrate and compare three different electrode types - 3/32" 7018, 3/32" 6013, and 1/16" easy-strike rods - on 16-gauge material using the Lincoln Sprinter 180Si welder. Discover why traditional 7018 electrodes at standard amperages cause burn-through on thin materials and explore amperage adjustments from 75A down to 40A to find optimal settings. Master the patch trick using de-fluxed electrodes as filler material to repair blow-through holes, and understand when to switch to 6013 electrodes for shallow-penetration welding strategies. Compare downhill versus uphill welding techniques on thin-gauge materials and learn why downhill provides superior control and cleaner fusion. Explore proper fit-up and heat placement techniques for butt joints, inside corners, and outside corners, while understanding when to step up to 1/8" wall thickness for optimal 7018 performance. Practice advanced techniques including vertical welding at 69A sweet spots, fast downhill outside corner methods, and gap-bridging using sacrificial filler rod assistance. Gain insights into electrode selection based on base metal thickness, proper setup configurations, and troubleshooting common issues like slag problems and arc reignition difficulties.
