LINCOLN ELECTRIC K1170 Stick Welder, Smooth arc, 40-225 AC, 230 V, 50 A

Lincoln Electric K1170 stick welder is a welding process that uses a consumable electrode coated in flux to lay the weld. It produces smooth arcs for welding mild steel, low alloy, stainless steel and cast iron. This welder is used across industries and projects, such as construction, shipbuilding, manufacturing, oil, structural welding, mining and steel fabrication.

Working Mechanism:

• Ensure the stick welder is placed on a stable and level surface.
• Connect the welder to a suitable power source using the attached input power cable and NEMA 6-50P plug.
• Turn on the power switch of the welder.
• Select the desired welding current by adjusting the amp selector switch.
• Prepare the welding area by cleaning the workpiece and ensuring proper ventilation.
• Insert the electrode into the electrode holder.
• Hold the electrode holder securely and make contact with the workpiece.
• Strike an arc by briefly tapping the electrode against the workpiece and then quickly withdrawing it.
• Maintain a consistent arc length and move the electrode along the joint at a steady pace.
• Complete the weld bead and release the electrode holder trigger to stop the welding process.
• Allow the weld to cool before inspecting the quality of the weld bead and making any necessary adjustments.

Features:

• It is equipped with a pre-attached 6 ft input power cable and NEMA 6-50P plug for quick setup and connection to power sources.

Frequently Asked Questions:

Q. What is the difference between stick and MIG welding?

A. While some contend that stick welding boasts superior strength compared to MIG welding due to its deeper penetration on thicker materials, MIG welding excels in producing quality welds on thinner metals with a smoother finish and reduced risk of burn-through, making it the preferred choice for such applications.

Q. How do I maintain my Lincoln Electric K1170 stick welder?

A.

• Regularly eliminate any dirt, dust or debris buildup.
• Look for signs of wear or damage and replace them if needed.
• Check for wear or damage and replace as necessary.
• Ensure it's free from contamination or moisture. Replace if needed.

Q. What is the operating current & voltage rating of this Lincoln stick welder?

A. It has an amperage rating of 225A at 25V.
