Who it fits

Key specs explained for this welder

135 Amp output

This rating defines the maximum current the machine can deliver. It allows you to weld mild steel up to 2/5 inch thick. This capacity suits thin to medium gauge metals common in automotive repair and light fabrication. If you need to weld thicker structural steel, you may require a higher amp unit. This output level balances power with portability for general use.

3-in-1: Flux Core MIG, Lift TIG, Stick

You get three distinct welding processes in one device. Flux core MIG works without external gas, ideal for outdoor work. Stick welding handles rusted or dirty metal. Lift TIG allows aluminum welding without a high-frequency start. This versatility means you do not need separate machines for different tasks. It is practical for hobbyists who encounter varied materials and conditions.

Synergic control with voltage fine-tuning

The machine automatically matches voltage to your wire feed speed. This reduces guesswork for beginners. You can still adjust voltage by minus 3 to plus 3 volts for specific needs. This feature simplifies setup while retaining control for experienced users. It ensures consistent arc stability. Compare this to manual machines where you must balance two settings independently.

11.4 lbs weight

This low weight makes the unit easy to carry to job sites. You can lift it with one hand. The compact size fits in small vehicles or tight workspaces. It reduces fatigue during long projects. If you frequently move your welder, this portability is a significant advantage over heavier industrial units. It supports on-the-go welding tasks effectively.

Lift TIG torch included

You receive the necessary torch for TIG welding right out of the box. There is no need to buy this accessory separately. This inclusion lowers the initial barrier to trying TIG welding. It allows immediate use of the lift TIG function for aluminum or stainless steel. This is a practical benefit for buyers who want a complete starter package without extra purchases.

Design and build details

The unit measures 14.57 by 6.10 by 8.86 inches and weighs 11.4 pounds. According to the listing, this compact size and light weight make it easy to carry for on-the-go projects. A built-in carrying handle supports this portability. You can move it between workshops or job sites without significant effort. The casing features a black and red finish. This color scheme is standard for industrial tools and helps hide minor scuffs during transport.

The front panel includes a digital display. This screen shows real-time current data, allowing you to monitor settings while welding. The interface supports synergic control, which automatically matches voltage to the wire feed speed. You can fine-tune voltage adjustments between negative three volts and positive three volts. This layout simplifies setup for beginners while offering precision for experienced users.

Safety features are integrated into the design. The machine includes protections against over-current, over-load, and over-heating. It also compensates for voltage fluctuations to maintain stable output. These safeguards protect the internal components and enhance user safety. The inclusion of a lift TIG torch means you can start TIG welding immediately after unboxing. No separate purchase is required for this accessory. The design prioritizes functionality and ease of use in a small footprint.

Setup and daily operation guide

Setting up the YESWELDER FLUX-135PRO begins with unpacking the unit and its included Lift TIG torch. The listing confirms the torch is included, allowing you to start Lift TIG welding immediately without a separate purchase. The machine supports .030 and .035 inch welding wire on 2-pound spools. You load the wire into the feeder and connect the appropriate torch or electrode holder for your chosen process. The digital display provides real-time current monitoring, which helps you maintain precise control during setup and operation. The interface is designed for clarity, ensuring you can see your settings clearly. For MIG welding, the synergic control simplifies the process. When you adjust the wire feed speed, the voltage automatically matches a recommended value. You can fine-tune the voltage between negative three and positive three volts if needed. The wire feed speed ranges from 120 to 420 inches per minute for .030 wire and 120 to 308 inches per minute for .035 wire. This automatic matching reduces guesswork for beginners while offering enough adjustability for experienced users. During daily use, the machine handles flux core MIG, stick, and Lift TIG processes. For stick welding, you can adjust Hot Start and Arc Force to enhance performance with E7018 and E6011 rods. Safety features like over-current, over-load, and over-heating protection engage automatically. The unit also includes compensation for voltage fluctuations, ensuring stable operation even in environments with inconsistent power. The compact size and light weight make it easy to reposition as needed for different projects.

Before You Buy This Welder

You should verify your power source before connecting this unit. It requires a standard outlet, but ensure the circuit can handle the load without tripping. Since it supports multiple wire gauges, check your local suppliers for .030 and .035 flux core wire. You will also need compatible electrodes for stick welding, such as E7018 or E6011 rods. Regular upkeep involves keeping the wire feed mechanism clean to prevent jams. Inspect the included Lift TIG torch cable for wear after heavy use. This machine fits well if you need a single tool for light fabrication. It complements heavier-duty options if you only occasionally need lift TIG. For daily industrial work, you might want a higher amp model. This unit is best for hobbyists or those with limited space. Keep the digital display clean for clear readings. Store it in a dry place to protect the internal components from moisture and dust accumulation.

Check before you buy

• Verify your electrical outlet can handle the load.
• Check local availability of .030 and .035 wire.
• Ensure you have compatible stick welding electrodes.
• Inspect the included Lift TIG torch cable.
