PUWU 135A vs 160A Specs
Welding processes
The PUWU 135A is a 3-in-1 unit that handles flux core MIG, stick, and lift TIG welding. It does not list gas MIG as a supported process in its published specifications. The PUWU 160A is a 4-in-1 machine. It supports gas MIG, flux core MIG, lift TIG, and stick welding. If you need to weld with shielding gas for cleaner results on steel, the 160A is the only option. The 135A is limited to gasless flux core for MIG applications. This is a significant functional difference for fabrication work.
Amperage output
The PUWU 135A is rated for 135 amps maximum output. The PUWU 160A is rated for 160 amps maximum output. Higher amperage allows you to weld thicker materials or run higher heat settings. The 160A provides 25 more amps than the 135A. This extra power is useful for heavier gauge steel or faster deposition rates. The 135A is sufficient for thin sheet metal and light repairs. You should choose the 160A if you plan to tackle thicker structural steel or need more heat input for faster welding speeds.
Input voltage
The PUWU 135A operates on a single 110V input. The PUWU 160A features dual voltage capability, supporting both 110V and 220V inputs. Dual voltage allows the 160A to run on standard household outlets or higher power 220V circuits. Running on 220V can help maintain stable arc performance at higher amperage settings. The 135A is restricted to 110V circuits. If you have access to 220V power, the 160A offers greater flexibility and potentially better performance under load. The 135A is simpler but less versatile regarding power sources.
Wire compatibility
Both welders support .030 and .035 inch welding wire diameters. The PUWU 135A lists compatibility with .030 and .035 inch wires. The PUWU 160A adds .040 inch wire compatibility to its list. The 160A can handle slightly thicker wire, which is often used for heavier duty applications. Both machines feature synergic control to adjust voltage based on wire speed. The 135A adjusts voltage between -3V and 3V for fine tuning. The 160A offers manual adjustment for precise customization. The 160A has a slight edge in wire range.
Weight and size
The PUWU 135A weighs 10.8 pounds and measures 12.9 inches by 7.1 inches by 12.2 inches. The PUWU 160A weighs 10.25 pounds. The 160A is slightly lighter by half a pound. The 135A includes a handy carrying handle. The 160A includes a sturdy handle and a shoulder strap for easier transport. Both units are compact and portable for job sites or outdoor use. The size difference is negligible for storage. The 160A offers a shoulder strap for added convenience. The 135A is marginally larger but still very manageable.
Safety protections
The PUWU 135A includes overload, over-voltage, and over-current protection. It also features integrated VRD (Voltage Reduction Device) to minimize shock risk. The PUWU 160A includes over-current, over-load, and over-heating protection. It also protects against voltage fluctuations. The 135A explicitly mentions VRD, which is critical for damp environments. The 160A mentions over-heating protection, which the 135A data does not explicitly list. Both units are certified for safety, with the 135A noting CE, ETL, and UL certification. The 160A notes rigorous testing. Both offer robust protection systems.
Which PUWU welder fits you
You need dual voltage flexibility
The PUWU 160A supports both 110V and 220V inputs. This dual-voltage capability allows you to use the machine in more locations, including sites with higher power outlets. The 135A model is limited to 110V only. If you work in varied environments or need to switch power sources, the 160A offers greater electrical versatility for your projects.
You want gas MIG welding
The PUWU 160A is a 4-in-1 machine that explicitly lists Gas MIG as a supported process. The PUWU 135A is a 3-in-1 unit that handles flux core MIG, stick, and lift TIG, but does not list gas MIG in its specifications. If you require shielded metal arc welding with inert gas for cleaner beads, the 160A is the necessary choice.
You prefer lighter weight
The PUWU 135A weighs 10.8 pounds. The PUWU 160A weighs 10.25 pounds. While the difference is small, the 160A is slightly lighter. However, the 135A includes a .03" 2LB flux core welding wire in the box. If you want immediate readiness with included consumables and do not need the slight weight saving or gas MIG capability, the 135A is a practical option.
