Our story
A trusted provider of welding technology and electronic solutions
Our roots go back to 1968, when M/S. AFAQ BROS began manufacturing welding machines and equipment — becoming Pakistan’s oldest and most experienced name in the field. SH System Engineering carries that work forward, specialising in electrical heating upsetter machines, resistance welding plant and the accessories that surround them.
The reputation we hold in the market was not built on a single product. It came from continuous research and development, and from sustained support from the industrial sector over many years — customers who told us what was failing on the shop floor, and returned when we fixed it.
Today S.H.S is recognised across Pakistan’s automobile and engineering industry as a reliable manufacturer, importer, indenter and supplier of both new and used machinery, with particular confidence earned in automotive maintenance work.
“At S.H.S, no problem is insurmountable. We provide round-the-clock service to our contractual customers to resolve technical issues in our field, ensuring uninterrupted productivity.”
Our service commitment
Mission
Keep Pakistan’s production lines welding
To supply welding machinery and accessories that are engineered for the duty cycles our customers actually run — and to stand behind that equipment with parts, expertise and a response time measured in hours, not weeks. Every machine we build or import should reduce downtime, not add to it.
Vision
The region’s reference point for welding technology
To be the first name an engineering manager thinks of when a joint has to hold — extending our manufacturing depth, widening our import line and bringing international welding standards within reach of every serious manufacturer in the region.
Two sides of the business
We build here, and we source worldwide
Local manufacturing gives us control over specification and lead time. Our import line fills in everything a modern welding shop needs around it.
Local manufacturing
- All kinds of resistance welding machinery and accessories
- Welding transformers from 20 KVA to 200 KVA
- C-type and X-type suspension welding guns and trans guns
- All types of metal sheet consoles
- All types of mechanical work, including CNC
Import line
- Spot welding AC/DC inverter, MIG/MAG and stud welding machines
- Welding timer controllers — authorised distributor for Nadex, Japan
- Welding robots, paint robots and pick-and-place systems
- Water-cooled kickless cable and secondary cable
- Manual and electric chain hoists with electric trolley
- Welding electrodes — Cu, Cr and Zr tips, caps and shanks
- Electrical, electronic and underwater cable products

Core values
How we work with our customers
Engineering honesty
If a repair or an upgrade will serve you better than a new machine, we say so. Long-term accounts are worth more to us than a single invoice.
Built to the job
Machines are designed and customised to the customer’s requirement — throat depth, KVA rating, controls and fixture, rather than a fixed catalogue model.
Quality that is verifiable
Raw materials are tested before production and equipment is developed in compliance with international quality standards — backed by our AWS membership.
Available when it stops
Breakdowns do not respect office hours. Contractual customers reach our technical team around the clock, because idle production is the real cost.
Our journey
From a Karachi workshop to three countries
1968 — The foundation
M/S. AFAQ BROS is established in Karachi and begins manufacturing welding machines and equipment, growing into Pakistan’s oldest and most experienced producer in the field.
Into resistance welding
The product line widens from electrical heating upsetter machines into a full resistance welding range — spot, projection, seam, butt and rocker arm — along with the transformers and guns that drive them.
SH System Engineering is formed
A sister firm is created to combine manufacturing with a formal import and indenting operation, giving customers a single source for machinery, automation and consumables.
International recognition
Membership of The American Welding Society (AWS), USA, is secured, and an authorised distributorship for Nadex welding timer controllers from Japan is established.
Today — Karachi, Stuttgart, Gifu
Offices in Pakistan, Germany and Japan let us source, inspect and ship equipment directly, while local manufacturing and 24/7 technical support continue from Karachi.

Global presence
Three offices, one point of accountability
Sourcing and inspection happen close to the manufacturer. Your contract, your commissioning and your support stay with Karachi.
