Arc Ignition Features: Hot Start, Arc Force, Anti-Stick
Short answer: Hot start, arc force, and anti-stick are three words a stick welder listing may carry. Hot start names a brief current boost when the arc is struck. Arc force names a current increase when the arc shortens. Anti-stick names a current reduction when the electrode sticks to the work. All three describe the starting moment of a stick weld. A buyer reading a first stick machine will meet these words on stick and multi-process titles. When a title does not list them, the detail is simply not stated by the seller.
What arc ignition means on a listing
Stick welding, also called SMAW or arc welding, is a common process for a first-time welder. The Everlast site opens its stick welding article with that point and notes that no shielding gas is needed. The American Welding Society offers certification and education in welding, as its site describes. A stick weld starts when the electrode touches the work and the arc forms as the electrode lifts away. That moment is called arc ignition.
On a welder listing, three words describe how a machine behaves at that moment: hot start, arc force, and anti-stick. They are the words a buyer meets when comparing stick welder listings and multi-process welder listings used in stick mode.
Hot start on a welder title
Hot start names a brief boost of current at the instant the arc is struck. The boost is meant to get the arc going at the moment the electrode and the work meet. On a title, 'hot start' tells a buyer the machine includes the boost. 'Adjustable hot start' tells the buyer the boost can be set. The word appears on small 120V stick machines as often as on larger ones.
A title that carries 'hot start' is describing the first fraction of a second of the weld, not the whole weld. A buyer choosing a first stick machine will meet this word most often on stick and multi-process titles. The stick welder guides compare these titles on the stated details.
Arc force on a welder title
Arc force names a second behavior. When the electrode is close to the work and the arc shortens, the machine raises the current to keep the arc from going out. Forney describes its 100 STx as a 120V stick and DC TIG welder with arc-force control, and its 160 STx as a dual-voltage stick and DC TIG welder with adjustable arc force. Forney states up to 85 amps for the 100 STx and up to 160 amps for the 160 STx.
A title that says 'adjustable arc force' lets a buyer know the amount of the boost can be changed. A title that only says 'arc force' names the feature without saying how it is set. The same reading applies to arc length and how it is described.
Anti-stick on a welder title
Anti-stick covers the moment when the electrode does touch the work and stays stuck. When that happens, the machine lowers the current so the electrode can be pulled free. On a title, 'anti-stick' or 'anti-sticking' names that behavior.
Anti-stick is not a claim that the electrode will never stick. It is a response that takes over after the electrode is already stuck. A buyer should read it as a listed behavior, not as a promise. The arc strike method is explained in general terms on this site.
Reading the three words together
On a stick welder title, hot start, arc force, and anti-stick often appear together or in pairs. Together they describe the full starting moment: a boost to start, a boost when the arc shortens, and a reduction when the electrode sticks. The three words are not ratings; they are descriptions of the machine's behavior at the moment the arc is started.
A multi-process welder used in stick mode carries the same words on the stick side of its title. YesWelder lists the ARC-205DS PRO as a dual-voltage 205A stick and Lift TIG welder; the stick side is where a buyer reads the three starting words. A YesWelder guide shows how one maker names its stick machines. For a closer look at what a multi-process machine can do, see multi-process welders and what a multi-process welder can do.
| Word | Moment it describes |
|---|---|
| Hot start | The instant the arc is struck |
| Arc force | When the arc shortens during the weld |
| Anti-stick | When the electrode sticks to the work |
What a title may not say
Not every stick welder title names hot start, arc force, or anti-stick. A title without them is not saying the machine lacks them; it is saying the detail is not stated by the seller. The same rule applies to any feature on a listing: read what is named, and treat what is missing as unstated. A buyer can still shortlist the machine and treat the missing detail as an open question.
When a feature matters to you, the next step is a question to the maker, not to the listing. The maker's manual and specification sheet are the place to look for the words a title omits. For the best welder comparisons, the site's welder reviews are based on stated details only.
Questions to ask the maker
Once a listing is on a shortlist, the starting features become questions for the maker. If the title names hot start, arc force, or anti-stick, ask how each behaves and whether each is adjustable. If the title does not name them, ask whether the machine includes them at all.
The maker answers define what a title cannot say. Compare the answers across two or three listings before choosing a machine. The stick welder guides and multi-process welder guides list machines by stated details.
- Is hot start adjustable on this model?
- Does arc force have a fixed amount or can it be set?
- Does anti-stick work for every electrode size the machine can run?
- Which pages of the manual describe the starting behavior?

Questions
Are hot start and arc force the same feature?
No. Hot start describes a current boost at the moment the arc is struck. Arc force describes a current increase when the arc shortens during a weld. They act at different moments.
Does anti-stick stop the electrode from sticking?
Anti-stick reacts after the electrode is already stuck. It lowers the current so the electrode can be pulled free. It is not a claim that the electrode will not stick.
Do all stick welders list hot start, arc force, and anti-stick?
No. Some titles name one or two of the three, some name none. A title without them leaves the detail unstated, and the buyer can ask the maker.
What is the difference between arc force and adjustable arc force?
Arc force names the feature. Adjustable arc force names the feature and says the amount can be set. Forney uses both phrases on its stick welder listings.
Where do these words appear on a multi-process welder?
On a multi-process title, the stick side of the machine is where hot start, arc force, and anti-stick belong. The MIG and TIG sides use other starting names.
What if a listing does not mention any starting feature?
Treat the detail as not stated by the seller. Keep the listing on a shortlist if the rest of the title matches, and put the starting behavior on your list of questions for the maker.
