Arc Welding Machine
Arc Welding Machine (Product Code: SLE/MCE/11) is an inverter-type manual metal arc (stick) welding power source used to join steel with coated electrodes in fabrication shops, maintenance departments and welding training bays at technical institutes. Fabricators and welding instructors choose it for its 40–400 A output range at a 60% duty cycle from a 415 VAC three-phase supply, with an inverter frequency of up to 20 kHz. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the Arc Welding Machine Used For?
Stick welding strikes an arc between a flux-coated electrode and the workpiece; the arc melts both, and the flux coating shields the molten pool. This machine suits structural fabrication, repair of frames and brackets, pipe work with cellulose electrodes and general maintenance, and it is a common first process in welding and fitter training courses. Because it is an inverter set, the arc responds quickly to the welder's hand, and the auto-compensation function helps keep the bead shape consistent when mains voltage varies.
The ability to hold a stable arc on a 100 metre output cable makes it practical for site and yard work where the machine cannot sit next to the job. Set the current to suit the electrode size and joint, stay within the 60% duty-cycle rating at high output, and always use a proper welding helmet, gloves and good ventilation.
What to Specify When Ordering
- Confirm a 415 VAC three-phase, 50/60 Hz supply rated for the 18.2 kVA input.
- Output cable length you need, up to 100 metres.
- Whether you need electrode holder, earth clamp and cables quoted with the machine (ask us what is included).
- Number of welding stations for your workshop or training bay.

Related Workshop Machine Tools
A welding bay usually needs protective wear and complementary joining and machining equipment:
- Gloves, Welding — hand protection against heat and spatter during stick welding.
- MIG Welding Machine — wire-fed welding for longer continuous seams in the shop.
- Spot welding Machines — resistance welding for overlapping sheet-metal joints.
- Pillar Drilling Machine — drills bolt holes in welded frames and brackets.

Frequently Asked Questions
What is the output range of the Arc Welding Machine?
The Arc Welding Machine delivers 40–400 A of welding current, with a rated current of 400 A at a 60% duty cycle and a no-load voltage of 68 V, which covers light repair work through to heavier structural welding.
What input supply does the Arc Welding Machine need?
The Arc Welding Machine runs on a three-phase 415 VAC ±15% supply at 50/60 Hz. It draws 18.2 kVA with a rated input current of 27.6 A, so check that your distribution board and cabling are sized for that load.
Can the Arc Welding Machine be used with cellulose electrodes?
Yes. The Arc Welding Machine is listed as adaptable to down-direction welding with cellulose electrodes, and its auto-compensation function helps it keep a stable arc and good seam shape when the mains supply fluctuates.
How large and heavy is the inverter arc welder?
The inverter Arc Welding Machine weighs 33 kg and measures 21.5 x 11 x 21.5 inch, so it can be moved around a workshop or taken to site. Its 85% efficiency and 0.93 power factor also help keep running costs down.
Who supplies the Arc Welding Machine?
The Arc Welding Machine is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to technical institutes, fabrication units, dealers and importers in India and international markets. Send enquiries through the contact page.
Is a calibration certificate available for the Arc Welding Machine?
Calibration or test documentation for the Arc Welding Machine is not listed as standard. If your institute or client needs such paperwork, please discuss the requirement with us through the contact page before ordering.
