Mini tig welder mastery starts with knowing the system

If you’re weighing a mini tig welder for precision work in the garage, paddock, or jobsite, performance hinges on exact setup and technique. Compact TIGs can rival full rigs—when you know how to set power, gas, tungsten, torch, and sequence. Everything You NEED to Know About TIG Welding translates pro shop practice into clear settings, checklists, and fixes that prevent porosity, warping, and contaminated tungsten.

Written by AWS-certified pros with two decades on stainless, chromoly, and aluminum, it covers AC/DC selection, HF start vs lift-arc, gas lenses and cups, pedal vs torch switch control, pulse for thin stock, duty cycle management, and heat control for clean, repeatable beads. Expect fewer regrinds, smoother arc starts, tighter heat-affected zones, and real savings on gas and consumables—so your mini tig welder punches well above its size.

• Correct machine/torch pairing for 120V and 240V compact setups.
• Proven starting amps, tungsten, and gas flow for steel, stainless, and aluminum.
• Fast remedies for arc wander, pinholes, and crater cracking.
