How to Handle Adjust a Welding Machine Step by Step
When adjust a welding machine leaves you confused, worried, or unsure what it means, a clear step-by-step approach can help you sort the signal from the stress. This guide explains how to understand the situation, reflect on what matters, choose a practical next step, and know when to ask for trusted support.
Making Adjustments on Stick Welders
Find the amperage for a type and thickness of metal
- Jones Welding & Industrial Supply Company Welding Experts Expert Interview on a welding chart.
- Look for a stick welding amperage chart online or in your stick welder’s manufacturer’s instructions.
- Find the type of metal and thickness of the material that you plan to weld on the chart and look at the recommended amperage level that corresponds to those specifications.

Set the amps using the knob on the front of the machine.
- Look at the numbers around the amperage dial and find the recommended amperage for the thickness and type of metal that you’re going to weld.
- Turn the dial on the stick welder right to increase the amps or left to decrease the amps until the arrow on the knob points at the correct number of amps.

Use a stick welding rod with a diameter equivalent to the machine’s amps.
- The diameter of the rod, also known as the electrode, will be a decimal version of the amperage.
- Use a.125 in (0.32 cm) thick welding rod when you’re welding a material at 125 amps, for instance.

Changing a MIG Welder’s Settings
Use 1 amp per.001 in (0.0025 cm) of metal thickness as a general rule.
- The thickness of the material you are welding determines how much amperage is needed to weld it effectively.
- Turn the amperage dial on your MIG welder to the number that matches the thickness of the material you plan to weld to set the starting amperage.

Increase the wire size for higher amp ranges.
- It’s recommended to use.023 in (0.058 cm) wire for 30-120 amps,.030 in (0.076 cm) wire for 40-145 amps,.035 in (0.089 cm) wire for 50-180 amps, and.045 in (0.11 cm) wire for 75-250 amps.
- Selecting a thickness of wire that works for the different thicknesses of metal that you usually weld means you won’t have to change the wire often.
- It’s recommended to use.023 in (0.058 cm) wire for 30-120 amps,.030 in (0.076 cm) wire for 40-145 amps,.035 in (0.089 cm) wire for 50-180 amps, and.045 in (0.11 cm) wire for 75-250 amps.

Select the starting wire feed speed based on the amps you’re using
- Jones Welding & Industrial Supply Company Welding Experts Expert Interview.
- Set the wire feed speed at the number of inches per minute (ipm) recommended by your machine’s settings chart, if it has one, for the amperage level you’re welding at.
- Multiply the amps that you’re welding at by a multiplier that corresponds to the thickness of the wire you’re using, if you don’t have a settings chart.
- Multiply by 1 in (2.5 cm) per amp for.045 in (0.11 cm) wire, 1.6 in (4.1 cm) per amp for.035 in (0.089 cm) wire, 2 in (5.1 cm) per amp for.030 in (0.076 cm) wire, and 3.5 in (8.9 cm) per amp for.023 in (0.058 cm) wire.

Turn the volts dial to the manufacturer's recommended voltage
- Jones Welding & Industrial Supply Company Welding Experts Expert Interview.
- Look at the chart on your welding machine and find the voltage that corresponds to the material you’re welding.
- Move the voltage dial to the number that the chart recommends to find a good starting voltage.
- Jones Welding & Industrial Supply Company Welding Experts Expert Interview.
- Look at the chart on your welding machine and find the voltage that corresponds to the material you’re welding.
Choose a mid-range voltage that creates a strong, stable welding arc.
- Start making a weld on a scrap piece of metal that is the same material and thickness as the metal you plan to weld.
- Have someone decrease the voltage on your machine until the welding arc starts stubbing, then increase it again until the arc becomes unstable.
- Choose a voltage in the middle between these 2 voltage points.
- Start making a weld on a scrap piece of metal that is the same material and thickness as the metal you plan to weld.
- Have someone decrease the voltage on your machine until the welding arc starts stubbing, then increase it again until the arc becomes unstable.
Turn up the gas flow if there is a lot of surrounding airflow.
- Welding gas flow is measured in cubic feet per minute (cfm).
- Increase the cfm if you are working in a drafty area or keep it low if you are working in an enclosed shop where there is not a lot of surrounding airflow.

Controlling the Heat on TIG Welders
Move the foot pedal or hand amp control to change a TIG welder’s
- Push your foot down on the pedal to increase the amperage or let the pedal up to decrease the amperage, if your TIG welder has a foot pedal amperage control.
- Push the hand amperage control wheel forward to increase the amperage or roll it backwards to decrease the amperage, if your TIG welder has a hand control.
- Push your foot down on the pedal to increase the amperage or let the pedal up to decrease the amperage, if your TIG welder has a foot pedal amperage control.
- Push the hand amperage control wheel forward to increase the amperage or roll it backwards to decrease the amperage, if your TIG welder has a hand control.
- Push your foot down on the pedal to increase the amperage or let the pedal up to decrease the amperage, if your TIG welder has a foot pedal amperage control.
Turn up the amps to increase heat if your weld’s bead is too narrow and high.
- Increase the amps using your TIG welder’s foot or hand control to turn up the heat.
- This will widen and flatten your weld’s bead.
- Increase the amps using your TIG welder’s foot or hand control to turn up the heat.
- This will widen and flatten your weld’s bead.
- Increase the amps using your TIG welder’s foot or hand control to turn up the heat.
Lower the amps to decrease the heat if your weld’s bead is too wide and flat.
- Use your TIG welder’s hand or foot control to decrease the amps and turn down the heat.
- This will make your weld’s bead higher and more narrow.
- Use your TIG welder’s hand or foot control to decrease the amps and turn down the heat.
