Frequently Asked Questions - LA-17 LINCOLN ELECTRIC
How do I set the correct wire feed speed for MIG welding?
Refer to the welding parameter chart in the manual. A general starting point is to match the wire feed speed (in inches per minute) to the material thickness. For 1/4 inch steel, use about 300 ipm with 0.035 wire.
What polarity should I use for flux-cored wire?
For self-shielded flux-cored wire, use DC Electrode Negative (DCEN). For gas-shielded flux-cored wire, use DC Electrode Positive (DCEP). The LA-17 is polarity selectable.
Can I weld aluminum with this machine?
Yes, the LA-17 can weld aluminum using the TIG process with AC output or MIG with a spool gun. However, it requires additional accessories like a TIG torch or spool gun.
Why does the wire feed stutter?
Check for a dirty or worn drive roll, incorrect tension, or a kinked liner. Clean the drive roll and adjust tension. Replace the liner if necessary.
What safety precautions should I take?
Always wear a welding helmet, gloves, and protective clothing. Ensure good ventilation and keep a fire extinguisher nearby. Disconnect power before maintenance.
How do I change the polarity?
Open the side panel and swap the cables on the terminal posts. The positive terminal is typically marked red, negative black. For DCEP, connect the gun to positive and ground to negative.
The machine does not arc when I pull the trigger. What should I do?
First, check the input power and circuit breaker. Then inspect the gun trigger switch and cable connections. Ensure the work clamp is firmly attached to clean metal.
What is the duty cycle and why does it matter?
Duty cycle is the percentage of time in a 10-minute period you can weld at a given amperage without overheating. For example, 60% at 150A means you can weld for 6 minutes and then must cool for 4 minutes.
Can I use a generator to power this welder?
Yes, but the generator must provide clean, stable power with sufficient wattage. A minimum of 10,000 watts is recommended for the LA-17. Avoid low-quality generators that may damage the electronics.
Where can I buy replacement contact tips?
Lincoln Electric dealer or online. Use genuine Lincoln parts for best performance. The LA-17 uses standard size contact tips for 0.035 inch wire.
