The 3 phase, 415 volt PowerARC 280STH is the most advanced Stick welder that Everlast has ever offered. It is a fully digital DC Stick/TIG machine with TIG pulse capability (up to 250Hz). It features excellent stick arc performance with cellulose, iron powder, and low hydrogen welding rods. This means that the unit easily handles E6010, E 6011, E6013, E7014, E7018, and even stainless 309L or 316L electrodes thanks to the adjustable hot start and arc force controls.
A VRD function lowers OCV (Open Circuit Voltage) when the unit is being used in stick mode on jobsites that require it a VRD be fitted for safety or in any environment where electrocution of the user while welding is possible. The unit also features full TIG capabilities for welding Steel, Chrome Moly, Stainless, Titanium and about any weldable metal except Aluminum and Magnesium.
2T/4T Tig controls allows the user the option of using the unit with or without a foot pedal in TIG mode. It also features HF start TIG, and lift start TIG so the user has the ability to work in HF sensitive environments. A built in gas solenoid, with adjustable pre and post gas flow controls allow the unit to automatically control gas flow without the use of a manual gas valve located on the torch.
With up to 250 amps Stick, and 280 amps of TIG welding power, the PowerARC 280STH is designed to function equally well with both Stick and TIG processes. It clearly belongs in the PowerArc line as it is a perfect fit for pipelines, fab shops, and anywhere one or both processes might be needed to complete the job.
PLEASE NOTE: This model of PowerARC 280STH is available and configured to operate on a 415V ~3 Phase input power. To achieve the maximum performance out of your Everlast Machine please ensure your current breaker and wiring/socket setup at your place of use is sufficient enough to achieve this. For example you may be required to upgrade your breaker to a 32A dedicated circuit to suit, therefore allowing you to achieve your machines full duty cycle. If in doubt please contact your local licensed electrician for more info prior to purchasing and please see terms and conditions/warranty for more information.
INDUSTRIAL USE ONLY.
Maximum electrode size will ultimately depend upon manufacturer and type of electrode. It is possible that up to 1/4" electrode may be used if rated by manufacturer for 250Amp use.
Single/Multiple pass thicknesses recommended on basis of practical limits that take into consideration quality and standard production practices.
Although the PowerARC 280STH can be used to weld aluminum with the SMAW (Stick) process, welding aluminum with DC TIG is not recommended.
When using this unit with a generator, the generator must be certified as "clean power" by the generator manufacturer. This is usually considered to be less than 5% THD.
If using with a generator, use with a generator rated for at least 12,500 Surge Watts.
