Overview

Overview

A 300 amp welding machine you can carry to the job

The ARC 300 welding machine (model ARC300iS) gives you full 300 A stick welding in a compact case with one carry handle. Plug it into a 230 V socket at a small workshop, a 415 V two-phase or three-phase line in the factory, or a generator on site.

It welds mild steel, stainless steel and cast iron with electrodes from 1.6 mm up to 4 mm. A digital IGBT inverter keeps the arc smooth and the power factor high, and the protection lamp warns you before the machine overheats.

One 300 amp welding machine, every kind of supply

Most 300 A stick welders need a three-phase line. The ARC 300 welding machine does not. The ARC300iS also runs from a 230 V single-phase supply, so the same machine works in the factory, the small shop and the site.

230 VSingle phaseWorkshops, homes and sites with only a single-phase supply. The 230V lamp lights.
415 VTwo phaseSites where only two phases are available.
415 VThree phaseFactory lines for the heaviest electrodes. The 415V lamp lights.
Gen-setCompatibleRuns from a suitably rated generator on remote sites.
On site

Where the ARC 300 welding machine works

Stick welding does not need gas, so it works outdoors, in wind and on rusty steel. The IP23S case of the ARC 300 welding machine is made for that kind of work.

Question & Answers

FAQ

ARC 300 welding machine: questions buyers ask

What is the ARC 300 welding machine price?
The price depends on quantity, cable lengths and delivery city. WhatsApp +91 88008 82983 with these details and our team sends a GST quotation with the delivery time.
Does the ARC 300 welding machine run on single phase?
Yes. The ARC300iS runs on a 230 V single-phase supply and on a 415 V two-phase or three-phase supply, 50 or 60 Hz. The 230V and 415V lamps on the panel show which supply it is on.
Which electrodes can a 300 amp welding machine like the ARC300iS use?
Electrodes of 1.6, 2.5, 3.2 and 4 mm, for mild steel, stainless steel and cast iron.
What do Hot Start, Arc Force and VRD do?
Hot Start adds a short boost at the strike for an easy start. Arc Force adds current when the arc gets short, so the rod does not stick. VRD keeps the voltage at the holder low while you are not welding. You pick each one by pressing the Para/Function switch and set it by turning the knob.
What does the O.C lamp mean?
It is the protection lamp. It lights when the machine is overloaded or overheats. Leave it switched on so the fan can cool it; it resets on its own.
Can I run the ARC 300 welding machine on a generator?
Yes. The ARC300iS is generator compatible. Use a generator rated for the machine’s input power.
Can it be used outdoors?
Yes. The case is rated IP23S for outdoor use. Do not weld in rain, and keep the air vents clear.
ARC 300 or ARC 400: which one should I buy?
Choose the ARC 300 welding machine for 1.6 to 4 mm rods and the freedom to run on 230 V or 415 V. Choose the ARC400iS for long shifts on heavy plate on a three-phase line.
What comes with the machine?
The machine with its input cable, an electrode holder with cable and an earth clamp with cable. Confirm cable lengths with our team.
