TBD
- Quick.. where is the nearest fire extinguisher?
Equipment
- P&H TIG Welder
- Lincoln Weld-Pak 100 MIG Welder
- Oxy-Acetylene Torch
- Lincoln Wire Welder
Consumables
Let's Learn to TIG Weld!
References:
Machine settings: What material are you welding?
- Steel? If you are using steel, set the Polarity Selector Switch (large three position switch on the right hand lower area) to the full clockwise position, Direct Current Straight Polarity (DC Electrode Negative). You should be using the red tungstens (2% Thoriated) for DC TIG welding. The "High Frequency" selector can be on "Start" or "Continuous", but "Continuous" will mess up nearby radios and wear out the machine faster.
- Aluminum? If you are using aluminum, set the Polarity Selector Switch to the full counterclockwise position, Alternating Current (AC). You should be using the green tungstens (pure tungsten).for AC TIG welding. Switch the "High Frequency" selector to "Continuous".
Choose machine settings and tungsten based on the following chart:
