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. Science Lab Supplies supplies it from Ambala, India to institutes, contractors and distributors.
Specifications
The welder runs on 230 V at 50/60 Hz, delivers 20 to 120 A at a 60% rated duty cycle, and takes electrodes of 1.6 to 3.2 mm. Hot start, arc force, anti-stick and overload protection are built in, with thermostatic control and fan cooling, plus a carrying strap and handle.

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.
- Diploma workshop practice: introductory arc welding demonstrations.
Arc welding involves mains voltage, intense UV light, hot spatter and fumes. Trainees must use the face mask, 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 listed in the package 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.

Send booth numbers and site voltage through the contact page, or use the enquiry cart; tender buyers can check the lab tender page.
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.
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 are ordered separately.
Who supplies the Manual Metal Arc Welding Machine?
Science Lab Supplies supplies it from Ambala, India, to ITI centres, polytechnics, TVET colleges and contractors equipping 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.
Related Metal Workshop Equipment
Welding is one stage of a metal manufacturing workshop in which parts are also machined, drilled and ground. These four machines and accessories make up the rest of that workshop and can be quoted together with the welder.
- Center Lathe Machine — turning parts before or after fabrication.
- Upright Drilling Machine — drilling holes in plates and brackets.
- Drilling Machine Vice — clamps parts for drilling.
- Reciprocating Spindle Surface Grinder — flat grinding of machined parts.
