The HITBOX HBM200 is one of the most impressive options under £100, offering a combination of power, features, and ease of use that’s hard to beat at this price.
Powered by a 240V supply, it delivers a rated output of up to 200A, although the realistic working current sits closer to 140A, which is still more than enough for most DIY and light workshop tasks. This makes it suitable for welding thin steel, stainless steel, and medium-thickness materials.
This is a 3-in-1 multi-process machine, supporting gasless MIG (flux core), MMA (stick), and Lift TIG welding (TIG torch not included). This flexibility allows users to switch between processes depending on the task, making it far more versatile than traditional budget MIG welders.
One of its standout features is the one-knob synergic control system, which automatically adjusts voltage and wire feed speed based on your input. This simplifies setup significantly, especially for beginners who may struggle with manual tuning.
The machine includes a digital LED display, providing clear visibility of current and settings, even while wearing a welding helmet.
With a duty cycle designed for light to moderate use (around 60% at lower currents), it performs well for short to medium welding sessions. Built-in over-voltage, over-current, and overheating protection ensures safe operation and helps extend the machine’s lifespan.
It comes as a complete kit, including a 2.4m MIG torch, electrode holder, ground clamp, flux wire, and consumables—so you can start welding immediately.
