Hebei Juliang Technology Co., Ltd. is one of the leading manufacturers and suppliers of f1621 automatic plasma torch height controller in China. Please feel free to buy CE approved machinery made in China here from our factory. All customized machines are with high quality and competitive price.

Quick Overview

If you run a plasma table, you know the struggle: torch height drifts, piercings take too long, and electrode wear adds up. The F1621 Automatic Plasma Torch Height Controller fixes that. It keeps your torch at the right height in real time, so cuts stay clean and consumables last longer. No complex setup. Just plug it in and let it work.

Key Features You'll Actually Use

1V arc voltage accuracy – Consistent cut quality across different plate thicknesses
Dynamic perforation knob – Adjust parameters on the fly; cuts piercing time by 30% on stainless and aluminum
Thick plate ready – Handles 50mm carbon steel without slag sticking or electrode damage
Hypertherm compatible – Works with popular plasma power sources
Two LED digital tubes – Clear readout of voltage and status
The F1621 Automatic Plasma Torch Height Controller is built for shop floors, not labs. Simple enough for a new operator, precise enough for complex contours.

Design & Build

The F1621 comes in a compact 270*210*72 mm box weighing just 1.5 kg. That means you can mount it directly on the gantry or keep it in a control cabinet. The two LED digital tubes are easy to read from a distance, even with welding glare. And the new dynamic perforation knob is placed right where your hand expects it – so you can tweak settings mid-cut without hunting through menus.

Real-World Application

Shipbuilding – 50mm carbon steel plates with minimal dross

Steel structures – Long, uninterrupted cuts

Mining machinery – Abrasive materials that normally eat torches

General fabrication – Stainless, aluminum, mild steel

One customer in Vietnam was replacing electrodes every two days on 30mm plate. After switching to the F1621 Automatic Plasma Torch Height Controller, electrode life went to over a week. Same machine, same operator, just better height control.

Why This THC Beats Others

Problem	How F1621 Solves It
Slow piercing	Dynamic knob cuts time by 30%
Slag on thick plate	Real-time voltage adjustment prevents buildup
Complicated setup	Plug-and-play – no PLC programming
Electrode damage	Steady arc voltage keeps tip off the plate

Company Behind It: Hebei Juliang Technology Co., Ltd.

We're not a trading company. Juliang is a factory that designs, builds, and supports CNC cutting equipment. Started in 2014 with portable cutters, then gantries, then lasers. Today we hold multiple invention patents and a "High-Tech Enterprise" title in Hebei Province.

Quick timeline:

2014 – First portable cutting machine

2018 – Juliang officially founded, "Xin Juliang" brand registered

2020 – Laser welders and multiple patents

2022 – Entered export markets, named High-Tech Enterprise

2025 – Third factory expansion, 30,000W laser cutter launched

We sell directly to Southeast Asia, Russia, Africa, Europe, and the US. And we answer support calls ourselves – not a call center.

FAQ – F1621 Automatic Plasma Torch Height Controller

Q: Will the F1621 work with my non-Hypertherm plasma cutter?

A: Yes. The F1621 Automatic Plasma Torch Height Controller uses standard arc voltage feedback. It works with Hypertherm, Lincoln, ESAB, Thermal Dynamics, and most Chinese-brand plasma sources. If you're unsure, send us your power supply model – we'll confirm in one message.

Q: How do I adjust for thick plates like 50mm carbon steel?

A: Turn the dynamic perforation knob slowly while the torch is piercing. You'll see voltage change on the LED display. Our customers find that a slightly lower voltage setting (around 4–6V below normal) prevents slag adhesion without losing cut speed. We can walk you through it over video.

Q: What if the unit breaks after the warranty period?

A: Contact us anyway. We'll help you diagnose – often it's a loose cable or a simple setting. If a part is dead, we'll quote you the factory price (not retail). You only decide after knowing the cost. No pressure.
