Maintenance

• Dust should be removed with dry and clean compressed air regularly. If the welder is used in a heavily polluted environment with smoke and polluted air, dust must be removed from the welder each month.
• The pressure of compressed air should be kept low so that damage is not done to the smaller components in the welder.
• Regularly check the connection of the electrical cord in the welder and make sure all other connections are secured.
• Welder needs to be stored and used away from water, dirt or dust.
• This Welder is designed to operate on Single Phase 110 and 220 Volt power sources. (110v 120v 220v 240v) with a plus or minus variant of 15%
• Make sure that the vent of the welder is not covered or plugged to ensure the cooling fans can operate to their full potential.
• Ensure all fittings and connections from argon bottle to welder are secured correctly to prevent leaking.
• When using a generator the unit should be grounded reliably with a grounding rod driven into the ground.
• The Ground Clamp dinse connector is inserted into the work port on the welder and is turned clockwise to secure. The ground clamp is connected to a clean surface as close as possible to the welding operation to ensure a good ground.
• Install the TIG torch copper nut connection (place supplied plastic sleeve on nut connection) from the torch cable connection to the TIG port, and tighten clockwise.

Specifications

• Dimensions: 22″ x 20″ x 9″
• A duty cycle of 60% at 200A for TIG welding, and 35% at 155A for stick
• Input voltage: 110V/220V
• This welder adopts rectifiers designed with advanced inverter technology.
  • The inverter TIG welding power uses high-power IGBTs to turn the working frequency of 50/60Hz to high frequency (20KHz or higher).
  • Then voltage is reduced and current is regulated.
  • This welder is a multi-purpose unit composed of DC pulse TIG welder and AC pulse TIG welder, and DC Stick welder (MMA).
  • This welder allows you the versatility of welding various types of metal including aluminum.
