Haozhifeng supplies this heavy duty Cast Iron TIG Torch Switch Housing as a robust alternative to conventional plastic torch switch covers. Manufactured in‑house with precision sand casting processes, this component is built to house and protect micro‑switches, spring assemblies and control cables inside TIG torch handles. Its rear threaded locking feature secures power cables well, minimizing wire damage from repeated pulling on site.
This Cast Iron TIG Torch Switch Housing is a sturdy replacement part designed for TIG welding torch handles. It is built to fit and protect the internal micro switch, springs and control cables. The rear threaded structure firmly locks the torch cable to avoid loose connection and wire damage during frequent use. Different from ordinary plastic housings, this iron housing is made for heavy welding work. It resists heat, shock and long-time continuous operation. Supplied in raw cast state, it supports further machining and surface finishing to meet different customer assembly and usage needs.
- Made of high quality cast iron with solid one piece structure, stable size and good durability
- Reasonable internal cavity space, perfectly compatible with standard torch switch accessories
- Rear thread locking design effectively prevents cable pulling and falling off
- Uniform wall thickness, strong resistance to drop, impact and cracking
- Reserved assembly positions for easy and smooth switch installation
- Support custom machining, painting and other secondary processing
More durable than plastic housing: Iron material is not easy to break or crack during daily workshop collision and dropping, greatly reducing replacement frequency.
Heat resistant for long work hours: Will not soften or deform under welding high temperature, keeping stable switch performance during continuous welding.
Good assembly match: Standard casting size ensures the internal switch fits tightly without loose or stuck problems.
Reliable cable protection: Thread locking design bears cable pulling force, protecting internal wires from breakage and signal failure.
Strong practicability: Suitable for all kinds of heavy-duty welding scenarios, with long service life and low comprehensive use cost.
Flexible customization: Support size adjustment, machining and surface treatment according to customer requirements.

A1: Plastic covers are easy to crack, break and deform under welding heat and daily drops. Our Cast Iron TIG Torch Switch Housing is much tougher, heat resistant and dimensionally stable. It greatly reduces replacement frequency and lowers overall using cost for workshop long-term operation.
A2: Yes. The internal cavity and overall structure follow common industrial standard sizes, which fit most regular micro switches and spring assemblies. We also support custom machining if you need special fitting size.
A3: Normally we supply raw casting blanks. No finishing processing inside. It allows customers to do secondary machining, drilling, painting or powder coating according to their own production standards.
A4: Yes. The rear threaded locking design fixes the cable position tightly. External pulling force acts on the housing instead of internal wires, which efficiently avoids cable loose and signal interruption problems.
A5: We support blackening, spray painting, powder coating and varnish dipping. All treatments provide good anti-rust and anti-corrosion performance for different working environments.
A6: Sure. We can adjust dimensions, process precision machining, and offer custom surface treatment based on customers’ drawings or samples. Stable mass production capacity is available.
A7: No. This listing is only for the cast iron housing, without micro switch, spring or control cable.
