Welding Systems

Common types are MIG (wire feed) for bodywork and sheet metal, TIG for precise or aluminum welds, and stick (arc) welders for heavy repairs and rusted metal; multi-process machines that combine MIG/TIG/stick are also available

Match amperage to material thickness—MIG systems around 100–200 A cover most auto repairs—and pick a duty cycle that supports your typical job length (e.g., 20–60% at rated output); higher duty cycles are better for continuous work or thicker materials

Prioritize a certified welding helmet with proper shade and auto-darkening, a respirator or fume extraction for welding-coated metals, ground clamps and quality leads, and thermal overload protection or cooling fans on the machine

Many compact MIG and inverter-based welders run on standard 120V circuits useful for home garages, while higher-amperage TIG or MIG machines often require 240V; check the unit's voltage, plug type, and required breaker capacity before purchase

Regularly clean the machine and vents, inspect and replace consumables (contact tips, nozzles, liners), check cable insulation and connections, and keep shielding gas and wire spools dry and corrosion-free

MIG systems use wire and shielding gas, TIG uses tungsten and usually inert gas, and stick uses coated electrodes; consumable cost depends on frequency of use, material type, and whether you need specialty wires or gases for stainless or aluminum

For sheet metal and body panels look for low amp control, pulse or spot-weld modes, and good arc stability at low wire feed speeds; for structural or frame work seek higher maximum amperage, deeper penetration, and robust duty cycle
