When you're choosing the next piece of welding soldering equipment, the first question is which gap in your shop you need to fill. The FEIFANKE 135A Flux Core MIG Welder costs $99.99 and gives you a multi-process starter machine. The Taishi Water Pump Water Chiller costs $235.12 and is built for one supporting job: keeping a TIG torch cool during long work sessions. So the decision isn't really welder versus cooler-it's new capability versus better endurance on an existing setup.
Quick verdict
If you don't yet have a working welder, the FEIFANKE 135A has the broader job to do: it's the first machine that can actually make welds. Pick the Taishi water cooler when TIG is your primary process and your torch is running hot enough that heat management is slowing you down. It won't add welding processes, but it can make the ones you already use more sustainable.
Comparison at a glance
| Feature | 135A Flux Core MIG Welder | Water Pump Water Chiller |
|---|---|---|
| Primary role | Multi-process welder for DIY projects | TIG torch cooler for extended work |
| Price | $99.99 | $235.12 |
| Welding processes | Flux core gasless MIG, lift TIG, stick | Not applicable |
| Cooling capacity | Not a cooler | 1500W (1L/min) |
| Duty cycle | 30% | Not applicable |
| Weight | 13.51 lb | 35 lb gross |
| Power input | 110V | 110V, 60Hz |
Where each product wins
- The 135A Flux Core MIG Welder wins when you're starting from zero and need one tool that can produce welds on its own.
- The Taishi Water Pump Water Chiller wins when you already have a TIG torch and the workload is heavy enough that torch heat is a limiting factor.
Product notes
FEIFANKE 135A Flux Core MIG Welder
The FEIFANKE is a portable IGBT inverter wire-feed welder that runs gasless, so you can set up without shielding gas. It covers flux core MIG, lift TIG, and stick in one unit, with a semi-automatic feed and an LED display. The synergic control lets you enter the wire diameter or choose an amperage in the 30-135A range, and the machine adjusts voltage and wire speed for you. It even suggests metal thickness. The 30% duty cycle and 13.51 lb weight point to intermittent home-garage use rather than continuous production, and that's the main limitation: you'll need to pause during longer passes. Also, lift TIG requires an extra torch, so the full multi-process range isn't available straight out of the box.
Taishi Water Pump Water Chiller
Not another welder, the Taishi is a dedicated cooler for a TIG torch. Its 1500W cooling capacity at 1L/min flow is the key spec, and on a 110V, 60Hz setup that makes it a straightforward addition to a TIG station. The 18"×10"×13" dimensions and 35 lb gross weight tell you to plan for bench or cart space. If your sessions are short and occasional, this unit is more machine than the job needs. If you're doing long TIG runs, though, it gives you a concrete way to manage heat and keep the torch comfortable. The trade-off: it adds cooling but no new welding capability, so it makes sense as a second purchase once the welder is already in place.
Final choice by use case
Choose the 135A Flux Core MIG Welder if you're equipping a home or garage shop and want one portable unit for repairs, auto work, farm equipment, and creative metal crafts. It's the tool that opens the door to actual welding.
Choose the Taishi Water Pump Water Chiller if you already have a TIG torch and your sessions are long enough that heat buildup becomes the bottleneck. It's a supporting upgrade with a specific, measurable cooling job.
If your shop has neither, buy the welder first and treat the cooler as the next addition when your TIG workload justifies it.
