Choose your voltage version
Select either 110V or 220V in the purchase options to match your intended power supply. These are separate versions, rather than a statement of automatic dual-voltage operation. The plug type is not specified; contact us to confirm the plug you need before ordering.
The pictured accessory kit
One set includes the machine, a welding pen with holder and base, a gauge assembly, clear glasses, tweezers, small consumable tools, the T-10 rotary accessory, USB and connecting leads, a power adapter and a printed manual. Fine consumables are supplied as pictured, without a specified individual count. Argon gas and a cylinder need to be arranged separately.
For your workbench
The pen has its own support beside the machine. Use the supplied manual for the equipment setup and controls. The size table below separates the machine body from its packaging. Browse more power tools or ask us about the voltage and plug.
