General

TIG welding is most commonly used to weld thin sections of stainless steel and non-ferrous metals such as aluminum, magnesium, and copper alloys. The process grants the operator greater control over the weld than competing processes such as shielded metal arc welding and gas metal arc welding, allowing stronger, higher-quality welds. However, TIG welding is comparatively more complex and difficult to master, and furthermore, it is significantly slower than most other welding techniques.

We have the Lincoln Precision TIG 185.

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.
