Which one should you choose?
Choose YESWELDER 205A Dual-Voltage Multi-Process Welder if
- You need to weld thicker steel or aluminum using a spool gun
- You have access to a 220V outlet for higher performance
- You want a single machine for diverse fabrication tasks
Choose YESWELDER 135A 3-in-1 Flux Core Welder if
- You only have standard 110V household outlets
- You prioritize portability and lighter weight for on-site work
- You mainly weld thin mild steel with flux core wire
Verdict: Choose the 205A dual voltage model if you need higher amperage, aluminum welding capability, or the flexibility of 220V power. The 135A 110V model is better for lightweight, portable jobs on mild steel where you only have standard household power. Your choice depends on your power source and material thickness needs.
Dual Voltage vs 110V Key Differences
Input Voltage
The YESWELDER 205A Dual-Voltage Multi-Process Welder supports both 110V and 220V input. This dual voltage capability allows you to switch between standard household outlets and higher-power industrial circuits. The YESWELDER 135A 3-in-1 Flux Core Welder is rated for 110V input only. This means it relies entirely on standard single-phase power sources. If you frequently work in environments with available 220V outlets, the dual voltage model offers greater flexibility. It can draw more power for heavier tasks without tripping breakers. The 110V model is limited to lower voltage sources, which may restrict performance on thicker materials.
Amperage
Amperage determines the maximum current output for welding. The YESWELDER 205A Dual-Voltage Multi-Process Welder provides up to 205 amps. This higher amperage allows you to weld thicker steel plates and run larger diameter wires with ease. The YESWELDER 135A 3-in-1 Flux Core Welder offers a maximum of 135 amps. This output is sufficient for thinner materials and light fabrication work. The 205A model handles a wider range of material thicknesses. If you need to weld heavy structural steel, the higher amperage is essential. For thin auto body panels or light repairs, the 135A output is adequate.
Welding Process
Both machines support MIG, flux core, stick, and lift TIG welding processes. The YESWELDER 205A is marketed as a 5-in-1 unit, explicitly listing Gas MIG, Flux Core MIG, Spool Gun MIG, Lift TIG, and Stick. It includes spool gun compatibility for aluminum welding. The YESWELDER 135A is a 3-in-1 unit focusing on Gasless Flux Core MIG, Lift TIG, and Stick. It does not list gas MIG or spool gun support. The 205A model offers more versatility for different metals and shielding gas requirements. The 135A model is simpler, relying on flux core for most tasks. Choose the 205A if you need gas MIG or aluminum welding capabilities.
Portability
Size and weight affect how easy the welder is to move. The YESWELDER 135A 3-in-1 Flux Core Welder weighs 11.4 lbs and includes a carrying handle. Its compact dimensions make it easy to transport to job sites or store in a small garage. The YESWELDER 205A Dual-Voltage Multi-Process Welder is larger and heavier, though exact weight is not listed. Its dimensions are 20 x 16 x 14 inches, which is significantly bulkier than the 135A model. If you need to carry the welder frequently, the 135A is more portable. The 205A is better suited for stationary use in a workshop.
Material Thickness
The maximum material thickness you can weld depends on the amperage. The YESWELDER 135A 3-in-1 Flux Core Welder is rated for mild steel up to 3/32 inch thick. This limit is defined by its 135A output. The YESWELDER 205A Dual-Voltage Multi-Process Welder has a 200A output capability, allowing it to weld much thicker steel. It is described as suitable for both thin and thick materials. The higher amperage of the 205A model provides a wider range of material compatibility. If you plan to weld plates thicker than 3/32 inch, the 205A is necessary. The 135A is limited to lighter gauge metals.
Which welder fits your workflow
Users needing 220V power for thicker metal
The YESWELDER 205A handles dual voltage input, letting you switch between 110V and 220V circuits. This flexibility supports higher amperage output for welding thicker steel. If you work in fabrication or automotive settings requiring robust power, this dual voltage capability ensures stable performance across different power sources without needing adapters.
Beginners welding thin auto panels indoors
The YESWELDER 135A is designed for thin materials, tackling mild steel up to 3/32 inch thick. Its synergic control matches voltage to wire feed speed automatically, reducing burn-through risks. The compact 11.4 lb size and included flux core wire make it ideal for beginners working on auto body panels in standard 110V outlets.
Outdoor welders avoiding gas cylinders
This 110V unit uses flux core wire, eliminating the need for shielding gas cylinders. This feature is crucial for outdoor or windy environments where gas can disrupt the arc. The lightweight design and integrated carrying handle make it easy to transport. You get reliable lift TIG and stick capabilities alongside gasless MIG welding in one package.
Professionals needing precise manual voltage control
The YESWELDER 205A offers manual adjustment of voltage between -3V and 3V alongside wire feed speed. This level of control suits seasoned welders who prefer fine-tuning their arc characteristics. The digital display provides real-time current monitoring, allowing you to maintain precise settings for complex joints or varied material thicknesses during professional fabrication work.
