The 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.

Features & Benefits:

  • DC output
  • Commercial performance, excellent for pipe and shipyard use.
  • VRD function for reduced OCV in stick mode improves safety and operator protection
  • Full 2T/4T control parameters in TIG mode, including up and down slope, start and end amps
  • Setting for cellulosic/E6010/E6011 welding results in optimized stick performance
  • Hot Start Time adjustment in Stick mode improves arc starting characteristics
  • Hot Start Intensity adjustment in Stick mode reduces sticking upon striking an arc in Stick mod
  • Arc Force control improves short arc performance in stick mode
  • Pulse TIG function allows operation up to 250 pulses per second (Hz)
  • IGBT inverter features IGBT modules for improved reliability and ease of service

Standard Equipment: 

  • 26 series Air-Cooled TIG torch with 12.5 ft. cables and 35 Dinse connector
  • Torch Switch TIG with 12.5 ft. cable and 7 Pin female plug for 2T/4T operation
  • Stick Electrode Holder with 10 ft. cable and 35 Dinse connector
  • Ground Clamp with 10 ft. cable and 35 Dinse connector
  • Argon Regulator with Hose
  • Foot Pedal 22K
  • Consumable Starter Kit (tungsten not included)

Notes: 

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.

Minimum/Maximum: 

Stick:
  • Weld with minimum 1/16" electrode
  • Weld with maximum 3/16" electrode

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.

TIG:
  • Weld a minimum metal thickness of .007"
  • Weld a maximum metal thickness in a single pass 1/4"
  • Weld a maximum metal thickness in multiple passes of .5"

Single/Multiple pass thicknesses recommended on basis of practical limits that take into consideration quality and standard production practices.
