DEWALT WELDING MACHINE MMA/ LIFT TIG 260A DXWDMMA260

 MMA WELDING 

• DXWDMMA260  is inverter technology MMA welding machines.
• The welder is able to weld (MMA)rutile, basic, stainless steel and cast iron electrodes.
• This welding machine also offers the possibility of welding coated electrodes.
• Connect the ground clamp connector and that of the electrode holder clamp to the connectors of the device, choosing the polarity according to the coating of the electrodes.
• Connect the ground clamp to the piece to be welded and clamp the electrode to the electrode holder clamp.
• when the MMA function is activated, the no-load voltage can be reduced to 9v for safety reason by selecting the MMA VRD function.

Lift TIG WELDING              

• Lift Tig function can be activated via selecting lift TIG function.
• TIG DC welding can be started without HF arc ignition. 
• In sensitive environment where high frequency used for arc ignition can cause disturbance it is advisable to use this function.
• The arc now starts by touching the workpiece  with tugsten electrode.
• Plug the Ground Clamp cable into Positive Socket. Twist clockwise all the way to lock in place
• Plug the machine to a properly grounded 220VAC outlet.
• Turn on the Power Switch 'ON' on the back panel. The Power Indicator on the front panel will light up.
• Toggle the welding mode switch on the front panel to TIG mode.
• Fix the tungsten electrode so that it protrudes approximately 6mm from the torch nozzle.
• Tum on the gas at the gas regulator, then open the valve on the torch handle, check for gas flow and adjust flow rate as needed.
• Initiate the weld arc with a lift arc technique.
• Thermal protection is built in machine. If the machine overheats, thermal fuse will prevent further use and indicator will light up
