How pros choose the best tig welding machine—and get cleaner results

TIG Welding Secrets distills field-proven settings, setup checklists, and selection criteria so you weld faster with fewer defects. Whether you run a compact inverter or a top AC/DC rig, you’ll nail gas coverage, AC balance, pulse, and pedal control to stack uniform beads, prevent porosity, and keep heat-affected zones tight. You’ll also know which specs actually matter when comparing machines: true amperage range, duty cycle at temperature, low-end arc stability, start circuitry, and torch compatibility.

Created by AWS-certified fabricators and shop trainers with 15+ years in aerospace, motorsports, and aluminum work, this guide is strictly practical—repeatable parameters, inspection cues, and troubleshooting flows that cut rework and consumable waste. Use it to extract maximum performance from your current unit and to identify the best tig welding machine for your process, materials, and budget with confidence.

• Clear settings for steel, stainless, aluminum from 0.040"–3/16"
• Setup checklists: tungsten, cup and gas lens, flow, stickout
• Decision matrix: must-have features vs. nice-to-haves across brands
