MIG Versus Cold TIG Comparison
Welding processes
The AZZUNO 155A Dual-Voltage MIG Welder supports five distinct modes: Flux Core MIG, Gas MIG, Aluminum MIG, Stick, and Lift TIG. It is optimized for wire-feed operations. The AZZUNO 180A Cold Pulse TIG Welder offers DC high-frequency TIG, pulsed HF TIG, Cold TIG, Spot TIG, and Stick. It lacks standard MIG capabilities. If you need to weld aluminum using MIG or flux core, the first model is the only choice. If you require precise TIG control for stainless steel or copper, the second model provides the necessary modes. Your material dictates the process.
Amperage output
The AZZUNO 155A Dual-Voltage MIG Welder delivers up to 155A of welding current. This output is sufficient for general fabrication tasks and moderate thickness materials. The AZZUNO 180A Cold Pulse TIG Welder provides a higher maximum output of 180A. This additional amperage allows for faster deposition rates and the ability to handle thicker materials more efficiently. For users who frequently weld heavier gauge metals or require higher heat input for penetration, the 180A model offers a clear advantage in raw power capacity.
Aluminum compatibility
The AZZUNO 155A Dual-Voltage MIG Welder is specifically designed for aluminum. It supports .030"/.035"/.040" aluminum wire and even .045" aluminum in manual mode. It includes drive rollers suitable for soft aluminum wire. The AZZUNO 180A Cold Pulse TIG Welder does not support MIG aluminum welding. Its documentation explicitly recommends a different AC/DC model for aluminum work. If your primary project involves aluminum fabrication, the first model is the necessary tool. The second model is unsuitable for this specific material.
Control features
The AZZUNO 155A Dual-Voltage MIG Welder uses a simple interface with two buttons and two knobs. It includes SYNERGIC, 2T, and 4T modes for wire feed control. The AZZUNO 180A Cold Pulse TIG Welder features a large LED display for precise parameter adjustments. It also includes a memory function to save and recall up to 10 custom parameter sets. This allows for quick switching between different materials or tasks. The second model offers superior digital control and workflow efficiency for users who need repeatability.
Included accessories
The AZZUNO 155A Dual-Voltage MIG Welder package includes a MIG torch, electrode holder, ground clamp, gas hose, contact tips, nozzles, drive rollers, and one pound each of aluminum and flux-cored wire. The TIG torch is sold separately. The AZZUNO 180A Cold Pulse TIG Welder includes a TIG torch with consumables, electrode holder, ground clamp, and power adapter. It explicitly excludes a gas regulator and tungsten electrode. The first model provides a more complete starter kit for MIG welding, including wire and specific rollers.
