ARC Welding Transformer
Product Code : LSK-WEAWLM-10675
ARC Welding Transformer (SKU LSK-WEAWLM-10675) is an air-cooled, moving-coil AC power source for manual metal arc (stick) welding, intended for general-purpose fabrication and maintenance work. Welding instructors use it to teach basic arc striking, bead laying and joint welding with coated electrodes. Science Lab Supplies supplies it from Ambala, India, in 150 A and 200 A models, to ITI and TVET workshops, engineering colleges, tender contractors and distributors.
Specifications
Every technical detail of both models is listed in the table below. In short, they are air-cooled, moving-coil AC transformers for stick welding with a 60% duty cycle; the 150 A model runs on 230 V single phase, while the 200 A model takes 230 V or 400 V and thicker electrodes.

Applications and Experiments for the ARC Welding Transformer
This transformer is used for introductory and intermediate stick-welding practice on mild steel: striking and maintaining an arc, running straight beads and welding butt, lap and fillet joints. Its simple AC design makes it a practical welding machine for training institutes that need several identical booths.
- ITI Welder trade: arc striking, bead and joint exercises with coated electrodes, wearing a Welding Shield and Welding Leather Gloves.
- Diploma and B.Tech workshop practice: welding shop demonstrations and jobs.
- TVET fabrication modules: maintenance welding and repair tasks, with joints cleaned on an Angle Grinder.
Standard Scope of Supply
The ARC Welding Transformer is supplied as a single unit, in the 150 A or 200 A model you select, as described above. Welding cables, electrode holder, earth clamp and electrodes can be added as separate lines; any accessories you need are itemised on the quotation.
Packing, MOQ and Lead Time
Quotations are available for a single welder or for every booth in a new welding shop. Each one states the packing, delivery time and price for the quantity and model requested, and safety wear such as shields, gloves and aprons can be priced on the same quotation.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Uganda, the UAE, Saudi Arabia, Oman, the Philippines and Nepal. Tell us whether you need the 150 A or the 200 A transformer through the contact page or the enquiry cart; for a formal tender, refer to the lab tender page.
Frequently Asked Questions
What is the difference between the 150 A and 200 A models?
The 150 A model covers 75–150 A on a 230 V single-phase supply with SWG 12–10 electrodes. The 200 A model covers 50–200 A, takes 230 V or 400 V and uses electrodes up to SWG 8.
What safety precautions apply?
Arc welding produces intense UV light, spatter and fumes, and the machine runs on mains power. Trainees need a welding shield, gloves and apron, a ventilated booth and instructor supervision.
Who supplies the ARC Welding Transformer?
Science Lab Supplies supplies it from Ambala, India along with its other welding machines and workshop equipment for training institutes. Either model can be quoted on its own or with accessories.
Can it be quoted for a tender?
Yes. Give the model, quantity and delivery location and the quotation will be prepared item-wise against the specification above, stating packing, delivery time and price for each line.
