TIG Welding Machines

Compare a 180 A DC HF power source and 270 A AC/DC references with separate 230 V and 400 V three-phase duty ratings. Configure your material, current, site supply and torch package, or request parts for an existing machine.

Sizes & capacities

Manufacturer reference configurations

Compare published specifications for each configuration, then select a reference or enter your own requirements. Supply and the final configuration are confirmed in the quotation.

3 documented configurations. Review one specification at a time; your custom requirements are retained.

TIG AC/DC 270 A · three-phase 400 V

Power-source reference only. The manual labels these ratings TIG; they are not split into separate AC and DC tables. Torch AC duty is a separate limit: specify torch, cooling, cables and package for the required current. These ratings do not describe MMA duty or establish a material-thickness capacity.

Your specification

Configure your product requirement

Enter the capacity and site requirements you need. Your selections carry into the RFQ and remain editable before submission.

Essential operating requirements

Optional. For existing-equipment spares, leave the reference unselected and enter the manufacturer and equipment identity below.

State current, duty percentage and ambient temperature together, e.g. 200 A at 60% and 40 °C.

For example: the exact stainless or carbon steel grade on your drawing.

Additional dimensions and application details

Describe joint geometry, base metal, shop/site duty and WPS requirements; thickness alone does not establish welding capacity.

For example: earth lead, holder, regulator, remote control, cooler, trolley and torch consumables.

Equipment identification & spare parts

Identify the installed equipment and the part you need. Add nameplate photos, drawings or a parts-list extract in the RFQ attachments step.

Add the nameplate, part photo or drawing in the RFQ attachments.

Next: contact details, quantity and delivery. Leave unknown requirements blank and request help in the RFQ.

Applications

Fabrication, installation and maintenance welding. Specify the actual base-metal grade, joint and welding procedure for equipment selection.

Selection guidance

Compare supply voltage, phase, frequency, welding process and current at the required duty cycle. Specify electrode or wire diameter, shielding gas, feeder and torch cooling separately.

Technical notes

Reference ratings apply to the stated process, voltage and ambient temperature. A material or thickness request is not a validated welding procedure. Spare-parts requests can be submitted without selecting a new-machine reference; include manufacturer, model, serial number, part number and identification photos.
