Lincoln weld pak 100, no heat penatration on the D setting


I believe your voltage control rheostat (potentiometer) must be worn out. Check your owner's manual for the part number and request it, it's not expensive and it is an easy part to replace. If you are doing that would be a good idea to do the same for your speed control rheostat.
Or clean them if you can, take off all the carbon particles that it build up with the time.

Weld-pak 100 Hd Problem


There is a reset button located in the wire feed spool compartment,
check to see it stays in when pushed. It is a safety when the machine
overheats, it normally resets when machine cools off. If it is working properly I suggest contacting Lincoln Electric Dealer for service.

I have a lincoln sp-100 welder and despite having a good ground the weld quality is just not there. Any help is appreciated


Hi,
Let's troubleshoot this one:
1) Make sure you have the right polarity for the wire you are using: Innershield wire (no gas) ground clamp must be on the + side. Solid Wire (gas use) ground clamp to negative side.
2) If gas is used: Mild steel welding requires Argon/CO2 mix 75/25 or 90/10. Using pure CO2 you will create a lot of sparks and a lot of fumes. Stainless Steel welding requires a Trimix gas of Argon/Helium and CO2. Aluminum Welding requires pure argon. Any use of gas requires a steady gas flow of no more than 25 SCFH. If you use more than that or less you will find porosity on the welding.
3) Your work piece must be cleaned before welding (no grease, dirt or paint).
4) Check your machine welding chart for wire speed and voltage.
If you still experience problems with welding quality, check you input power voltage, make sure it doesn't fluctuate.
Goooooood Luck.

I have a lincoln power mig 255 and every time i weld little holes appear in the welds. what could this be?


Hi:

This could be a problem of gthe gas you are using. Make sure to use mix 75/25 argon/CO2 for mild steel welding, argon 100% for aluminum and trimix helium/argon/CO2 for stainless steel.
Also check your heat (voltage) 16-22 is enough for weld of most steels less than 1/2 inch.

What gauge exstention cord do i use for a lincoln weld pak 100?


Hi:

Weld pak 100 is a 120 volt unit, you will be ok with a gage 12.
Most 120V commercial extensions out there are 14 gage, if you want to buy one, choose no longer than 25 ft long.
With a 12 gage you can go to 50 ft. with no problems.

If this was useful to you please vote. Thanks.

The F 1 circuit breaker, manual reset is tripping not allowing it to weld. Could it be something as simple as the reset itself


Rated Output at 20% Duty Cycle 150 A at 16 VAC
150 A at 16 VDC Welding Amperage Ranges AC/DC 10 - 165A Max. Open-Circuit Voltage 80 V Amps Input at Rated Output AC-230V: 21A
DC-230V: 23A You need to configure the machine to specifications of the material you going to weld.That is :
-The material of the job
-And the proper amperage to use for the material.
-For aluminum you will use A/C
-Stainless Steele / Chrome Molly D/C

Aluminum MIG Welding
1. The best feeding of wire for aluminum is done with a spool gun. If you can't use a spool gun, use the shortest gun possible and keep the gun as straight as possible. Use Argon only for shielding gas. Only use a push gun technique when welding aluminum. 2. If you are having feeding problems, one thing you can try is a contact tip that is one size bigger than your wire. 3. The most common wire type is ER4043 for all-purpose work. ER5356 is a stiffer wire (easier to feed), and is used when more rigid, higher-strength weld properties are needed. 4. Clean the aluminum before welding, to remove the oxide layer. Use a stainless steel wire brush used only for cleaning aluminum. 5. Fill the crater at the end of the weld to avoid a crack. One way to do this is to dwell in the weld pool for a second at the end of the weld.

Check the voltage at the wire feed motor when the trigger is pulled.

I had a Weld Pak 100 that with 0 volts at the wire feed motor, and the problem wound up being that 2 of the big power (stud) diodes were shorted.

I dont know what kind of metals this wire type can do, it says fire power 1440 u235 flux wire, but not sure what kinds of aluminums or steels it can weld. Im a certifed MIG aluminum welder, but this is a...


Usually a flux core only welds steel. It is a higher penetration weld than a MIG. Usually it acts similar to 6011 rods in SMA (Shielded Metal Arc) welding -- a.k.a. stick welding -- if you're familiar with that. I don't believe there is such a thing as flux wire for aluminum. There may be stainless wire for it, but I've never seen it. It probably could also be used for building up cast iron and cast steel, but nothing structural. I have a Chicago Electric one and I love it -- simple and it penetrates hard. My 90 amp will weld to 3/8" without breaking a sweat and if I baby it will go to 1/2" or better. It is difficult to go much lower than 12 or 14 gauge though due to the high penetration.

How to quote stainless steel welding?


First, depending on where you live some shops(welders) will "quote you a price". check the yellow pages. Use a time and material guide. Material should be included with the price of the stainless...many times you could find a contract with the locaaaaaal gas co.(speciaiality type)e.g. helium O2 etc. good place to start.
