ARC630-2T
Dual operator arc welding machine · 630 A · MMA + gouging

Two welders. One 630 A machine.

The CRUXWELD ARC630-2T is a dual operator arc welding machine: one IGBT inverter with two electrode outputs, so two welders strike their own arcs at the same time. Each welder has their own current knob and digital display, and the same machine does air carbon arc gouging.

Overview

01

Two welders, one machine

How a dual operator arc welding machine runs two welders

Most fabrication bays run two stick welders side by side: two machines, two power drops, two sets of cables across the floor.

The ARC630-2T replaces both. Welder 1 and welder 2 each get their own output, current knob and display, and share one earth return to the job.

  • One machineto buy, move, connect and maintain.
  • One power dropinstead of two on the shop floor.
  • Two bays workingfrom a single 630 A station.

Electrode guide

Where each electrode sits on the 630 A scale

The ARC630-2T takes 3.2, 4, 5 and 6 mm electrodes. Pick a rod for each welder to see the typical current:

Gouging

Back-gouge and repair without a second machine

Air carbon arc gouging strikes an arc between a carbon electrode and the job, then blows the molten metal away with compressed air, leaving a clean groove. The ARC630-2T powers it as well as MMA welding.

Carbon electrode + compressed airThe arc melts, the air blows it out: a clean groovePLATE SECTION
  • Back-gougingOpen the root of a double-sided weld to sound metal.
  • Defect removalCut out cracked or porous welds for repair.
  • Joint preparationGroove plate edges before welding.
  • Site repairGenerator compatible for work away from the shop.

Gouging also needs: a gouging torch, carbon electrodes and compressed air.

Question & Answers

FAQBuyers ask

Dual operator arc welding machine: questions buyers ask

What is a dual operator arc welding machine?
It is one welding power source that two welders can use at the same time. The ARC630-2T has two electrode outputs (+1 and +2), each with its own current knob and digital display, and a common work return.
Can both welders set different currents on the dual operator arc welding machine?
Yes. Welder 1 uses CURRENT (1) and the AMP (1) display; welder 2 uses CURRENT (2) and the AMP (2) display.
What is the output current range of the dual operator arc welding machine?
20 to 630 A DC, for 3.2, 4, 5 and 6 mm electrodes. If both welders will run heavy electrodes at the same time, send us the sizes and our technical team will confirm the set-up.
Does the dual operator arc welding machine do air carbon arc gouging?
Yes. It supports MMA welding and air carbon arc gouging. Gouging also needs a gouging torch, carbon electrodes and compressed air, which we can quote with the machine.
What power supply does the dual operator arc welding machine need?
AC 415 V ±15%, three-phase, 50/60 Hz. Rated input is 32 kVA and 54 A. It is generator compatible.
Does it have hot start, arc force, anti-stick and VRD?
Yes. Arc force is adjustable from 0 to 100% on the front panel, hot start and anti-stick are built in, and VRD is selected with a switch on the panel.
How is it cooled and protected?
Forced air with dual cooling fans. It has an MCB on the rear panel plus overload and overheat protection. The enclosure is IP21, so keep it out of rain and snow.
How do I move the dual operator arc welding machine around the shop?
It stands on four swivel castors and has two handles on top for lifting and loading.
What is the dual operator arc welding machine price and delivery time?
WhatsApp +91 88008 82983 with the quantity, cable lengths for each welder, whether you need a gouging torch, and your city. Our team replies with a quotation and delivery time.
