Manual Metal Arc Welding Machine
Product Code : LSK-MMTM-10613
Manual Metal Arc Welding Machine (SKU LSK-MMTM-10613), commonly called an MMA or stick welding machine, is a portable MOSFET inverter welder for joining ferrous metals with coated electrodes. It suits welding bays in ITI centres, polytechnics and TVET institutes where trainees learn arc welding, and its compact size and low power draw help where mains supply is weak. Institutes, contractors and distributors can obtain it through Science Lab Supplies, which supplies it from Ambala, India.
Specifications
Electrical ratings, protection features and package contents of the MMA inverter welder are separated into individual rows below.

Applications and Experiments for the Manual Metal Arc Welding Machine
Trainees use the machine to strike and hold an arc, run beads and make butt, lap and fillet joints in low carbon, medium carbon and alloy steel. Its 20-120 A range covers the thin electrodes used in early practice as well as heavier joints.
- ITI Welder (Gas and Electric) trade: arc striking, bead running and basic joint practice.
- ITI Fitter and Sheet Metal trades: tack and joint welding in fabrication exercises.
- TVET fabrication modules: producing welded joints to a drawing, including pipe joints set up in a Pipe Welding Clamp.
- Diploma workshop practice: introductory arc welding demonstrations, with joints dressed afterwards using an Angle Grinder.
Arc welding involves mains voltage, intense UV light, hot spatter and fumes. Trainees must use the face mask, Welding Leather Gloves and protective clothing, weld only in ventilated bays and work under a qualified instructor.
Standard Scope of Supply
The complete package contains the welding machine, an electrode holder, an earth clamp, a face mask and a welding brush, packed in a carton box. Welding electrodes, gloves and protective clothing are not included and are quoted separately if required.
Packing, MOQ and Lead Time
If you need a welding machine for training institute booths, ask for one unit or a full bay. The quotation states packing, delivery time and price for that quantity, and electrodes or other TVET workshop equipment can be added to it.
Science Lab Supplies is a registered exporter holding an Importer-Exporter Code and can ship to buyers in the Philippines, Nepal, Bangladesh, Zambia, Rwanda and South Africa. Booth count and site voltage are the two details to include when you write via the contact page; the enquiry cart suits a multi-item list, and the lab tender page covers tendered orders.
Frequently Asked Questions
Which metals can this machine weld?
It is specified for ferrous metals: low carbon steel, medium carbon steel and alloy steel, using coated electrodes of 1.6 to 3.2 mm within its 20 to 120 A current range.
What is included with the welder?
The package includes the machine, electrode holder, earth clamp, face mask and welding brush in a carton box. Electrodes, gloves and protective clothing are ordered separately.
Who supplies the Manual Metal Arc Welding Machine?
Science Lab Supplies acts as supplier for this welder, dispatching it from Ambala, India, to ITI centres, polytechnics, TVET colleges and the contractors who fit out welding workshops.
Is it suitable where the power supply fluctuates?
It is designed to resist voltage fluctuation and keep the welding current stable, with low power consumption, which suits sites with an unreliable supply.
